CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9121813. [PMID: 36553255 PMCID: PMC9777501 DOI: 10.3390/children9121813] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Revised: 11/14/2022] [Accepted: 11/17/2022] [Indexed: 11/25/2022]
Abstract
Night sleep and parental bedtime practices have rarely been investigated in late talkers. This study aimed to explore: night sleep, parental bedtime practices, and their associations in late talkers as well as individual, socio-demographic, and socio-relational factors affecting them. Parents of 47 30-month-old late talkers, born low-risk preterm (n = 24) or full-term (n = 23), with an expressive vocabulary size ≤10th percentile measured by the MacArthur-Bates Communicative Development Inventory Words and Sentences, and normal cognitive abilities measured by the Bayley Scales, completed the Infant Sleep Questionnaire, the Parental Interactive Bedtime Behaviour Scale, and the Parenting Stress Index Short Form. Results showed slight settling difficulties, night wakings, and frequent co-sleeping in late talkers. Encouraging autonomy practices were frequently used by parents, rather than active physical comforting ones. Recurrent settling difficulties were reported by parents who often applied encouraging autonomy practices, whereas greater night waking problems and frequent co-sleeping were reported by parents who often left their child crying. Low-risk preterm birth and mother's parenting stress predicted total sleep difficulties and night wakings; first-born, high maternal education level and mother's parenting stress predicted settling difficulties; mother's parenting stress was the only predictor for co-sleeping and leaving to cry. These findings have relevant implications for improving late talkers' night sleep and their parents' bedtime practices.

Abstract
This study examined socioeconomic status (SES) and attachment security as predictors of infant nighttime sleep during the second year. Participants included 128 mothers (86% White) with infants (48.4% boys). Data collection took place between April, 2009 and February, 2014. At 12, 18, and 24 months, infant sleep was assessed via actigraphy and daily diaries, and attachment with the Attachment Q-Set. SES indicators included income-to-needs ratios and education. Lower SES predicted greater variability in sleep duration and later sleep timing only for less secure infants. Less secure attachment was associated with poorer sleep at both between- and within-person levels, especially when infants were 12 months of age. Results emphasize the complex interactive effects of environmental and relational factors on infant sleep.

The impact of reducing the frequency of night feeding on infant BMI. Pediatr Res 2022; 91:254-260.

Abstract
BACKGROUND Teaching caregivers to respond to normal infant night awakenings in ways other than feeding is a common obesity prevention effort. Models can simulate caregiver feeding behavior while controlling for variables that are difficult to manipulate or measure in real life. METHODS We developed a virtual infant model representing an infant with an embedded metabolism and his/her daily sleep, awakenings, and feeds from their caregiver each day as the infant aged from 6 to 12 months (recommended age to introduce solids). We then simulated different night feeding interventions and their impact on infant body mass index (BMI). RESULTS Reducing the likelihood of feeding during normal night wakings from 79% to 50% to 10% lowered infant BMI from the 84th to the 75th to the 62nd percentile by 12 months, respectively, among caregivers who did not adaptively feed (e.g., adjust portion sizes of solid foods with infant growth). Among caregivers who adaptively feed, all scenarios resulted in relatively stable BMI percentiles, and progressively reducing feeding probability by 10% each month showed the least fluctuations. CONCLUSIONS Reducing night feeding has the potential to impact infant BMI, (e.g., 10% lower probability can reduce BMI by 20 percentile points) especially among caregivers who do not adaptively feed. IMPACT Teaching caregivers to respond to infant night waking with other soothing behaviors besides feeding has the potential to reduce infant BMI. When reducing the likelihood of feeding during night wakings from 79% to 50% to 10%, infants dropped from the 84th BMI percentile to the 75th to the 62nd by 12 months, respectively, among caregivers who do not adaptively feed. Night-feeding interventions have a greater impact when caregivers do not adaptively feed their infant based on their growth compared to caregivers who do adaptively feed. Night-feeding interventions should be one of the several tools in a multi-component intervention for childhood obesity prevention.

Child maltreatment severity and sleep variability predict mother–infant RSA coregulation. Dev Psychopathol 2021; 33:1747-1758.

Abstract
AbstractRegulatory processes underlie mother-infant interactions and may be disrupted in adverse caregiving environments. Child maltreatment and sleep variability may reflect high-risk caregiving, but it is unknown whether they confer vulnerability for poorer mother–infant parasympathetic coordination. The aim of this study was to examine mother–infant coregulation of respiratory sinus arrhythmia (RSA) in relation to child maltreatment severity and night-to-night sleep variability in 47 low-income mother–infant dyads. Maternal and infant sleep was assessed with actigraphy and daily diaries for 7 nights followed by a mother–infant still-face procedure during which RSA was measured. Higher maltreatment severity was associated with weakened concordance in RSA coregulation related to the coupling of higher mother RSA with lower infant RSA, suggesting greater infant distress and lower maternal support. In addition, higher infant sleep variability was associated with infants’ lower mean RSA and concordance in lagged RSA coregulation such that lower maternal RSA predicted lower infant RSA across the still-face procedure, suggesting interrelated distress. The findings indicate that adverse caregiving environments differentially impact regulatory patterns in mother–infant dyads, which may inform modifiable health-risk behaviors as targets for future intervention.

Abstract
This longitudinal study examined developmental trajectories of infant sleep problems from 3 to 24 months old and investigated associations with infant-parent attachment security and dependency. In a sample of 107 Israeli families, number and duration of infant nighttime awakenings were measured at 3, 6, 9, and 24 months old, using mothers' and fathers' reports on the Brief Infant Sleep Questionnaire (BISQ). Infant-parent attachment security and infant-parent dependency was assessed at 24 months old, using the observer Attachment Q-Sort procedure (AQS) with both parents. Latent growth curve models showed a non-linear decline in number and duration of infant nighttime awakenings over time. A higher number and longer duration of infant nighttime awakenings at 3 months were associated with higher infant-father attachment security at 24 months. In contrast, longer infant nighttime awakenings at 3 months were predictive of lower infant-mother attachment security at 24 months. A steeper decrease in duration of infant nighttime awakenings was associated with higher infant-father attachment security and lower infant-mother attachment security. As a potential mechanism, paternal involvement in nighttime caregiving was explored in relation to infant-father attachment security. Results of our post-hoc analyses revealed no significant associations between paternal involvement in nighttime caregiving and infant-father attachment security. Our results highlight the need to examine potential mechanisms explaining the divergent associations of infant sleep problems with infant-mother and infant-father attachment security in future research.

Abstract
OBJECTIVE Infants' sleeping patterns can influence parents' sleep and their well-being. Infants' sleeping problems can evoke negative emotions from their parents because of the influence the problems have on parents' lives. However, little is known regarding the associations between infants' night sleep patterns and parents' overall negativity toward their children. The objective of this study was to study this association. METHODS In a longitudinal design, we followed infants and their parents from 9 to 18 months. Overall, 392 families participated in the study. Parents' negativity and children's sleeping patterns were assessed with questionnaires. RESULTS Parents' negativity and children's sleeping problems showed moderate continuity through the study's 9-month period. Children's sleeping problems at 9 months predicted an increase in mothers' (but not fathers') negativity at 18 months. Parents' negativity was not associated with infants' sleep problems. CONCLUSION The results of this study suggest that already in infancy, children's tendencies, in this case sleep, can evoke negative emotions in their mothers and highlight infants' roles in the intricate parent-child relationship.

Abstract
Previously, we have shown that neuromodulators are important factors in stress-induced emotional disorders, such as depression, for example, serotonin is the major substance for depression. Many psychological studies have proved that depression is due to insecure attachment. In addition, sleep is a major symptom of depression. Furthermore, serotonin is the substrate for both sleep and depression. To explore the role of sleep in the relationships between insecure attachment and depression, we investigated 755 college students with Close Relationship Inventory, Emotion Regulation Questionnaire, Self-rated Depression Scale, and Pittsburgh Sleep Quality Index. The results showed that (1) insecure attachment positively predicted poor sleep quality; (2) sleep quality partially affected depression, possibly due the same stress neuromodulators such as norepinephrine and cortisol; and (3) cognitive reappraisal moderated the mediating path leading from attachment anxiety to poor sleep quality. These findings highlight the moderating role of cognitive reappraisal in the effects of attachment anxiety on sleep quality and finally on depression. In conclusion, sleep quality links attachment anxiety and emotional disorders.

Abstract
Observed infant temperamental difficulty and infant sleep efficiency and sleep variability were examined as predictors of maternal depressive symptoms, maternal sensitivity, and family functioning. Eight observations at 8-months postpartum were used to assess infant temperament, and actigraphy was used to measure infant sleep for 1-week at the time of the 8-month assessment. Structured clinical interviews were used to assess maternal depressive symptoms between 5 and 12 months postpartum and at 15 months postpartum, and observational assessments were used to assess maternal sensitivity and family functioning at 15 months postpartum. Variability in infant sleep moderated the effect of infant temperament on maternal depressive symptoms, maternal sensitivity, and family functioning. Infant temperament was positively associated with maternal depressive symptoms when variability in infant sleep efficiency was high, but not when variability in infant sleep efficiency was low. Likewise, infant temperament was negatively associated with maternal sensitivity and family functioning when variability in infant sleep efficiency was high, but not when variability in infant sleep efficiency was low. Results underscore the importance of infant sleep for maternal and family health.

Abstract
Changes in nighttime sleep consolidation and daytime discontinuation have been observed in early life. Yet information about societal or cultural factors remains scant for implementing sleep recommendations. We aimed to provide pooled estimates of subjective sleep duration, number of nightwakings and sleep timing; to describe their age-related trends; and to determine potential cross-cultural disparities between predominantly-Asian (PA) and predominantly-Caucasian (PC) regions during the first three years of life. We performed this review according to the PRISMA guidelines. Overall, 102 studies with 167,886 children aged 0-3 y from 26 different countries/regions were included. Compared to PC regions, PA toddlers had shorter sleep duration and more frequent nightwakings. When PC regions were further divided into Pacific Rim and Europe, differences were much more evident between PA and Pacific Rim for all nighttime sleep parameters. Trends of nighttime sleep duration and bedtime for PC regions showed rapid changes over the first 3-6 mo before stabilizing to a plateau, whereas a different change was found for PA regions. In conclusion, an apparent cross-cultural disparity of the subjective sleep parameters already exists in early childhood. Improved operationalization of sleep parameters and more objective evidence are needed to establish cultural-sensitive recommendations this early in life.

Abstract
This longitudinal study examined the associations among infant crying, symptoms of sleeping problems, and attachment while considering the influence of maternal sensitivity and depressive symptoms. One hundred and five healthy full-term infants (42.9% female) were assessed for crying and symptoms of sleeping problems at 3 and 18 months via parental interview. Maternal sensitivity was measured through researcher observation, and attachment was measured at 18 months using the Strange Situation procedure. It was found that infant crying and symptoms of sleeping problems were not linked to the organized patterns of secure or insecure (avoidant versus resistant) attachment. However, when the disorganized attachment was considered, there were direct links found from infant crying and symptoms of sleeping problems at 3 months (β= .22, p< .05) and 18 months (β= .21, p< .05). Thus, crying and symptoms of sleeping problems as early as 3 months may indicate a disruption in the coherence of infants' relationship to their caretakers.

Abstract
Few studies have examined the longitudinal impact of birth status on the infant-mother relationship and on children's socio-emotional development. In the present study we investigated developmental patterns of such relationships [using the Emotional Availability (EA) Scales] in fullterm and VLBW/PT infants from infancy to emerging school age. Our objectives were to: (a) model the developmental trajectories of EA dimensions (maternal sensitivity, structuring, non-hostility; child responsiveness, involvement) in a VLBW/PT and fullterm sample, (b) identify potential effects of VLBW/PT status on these trajectories, and (c) determine whether the effects of VLBW/PT status on children's socio-emotional development (child EA) remained after accounting for the effect of maternal EA. Child-mother dyads (n = 109) were observed in home-based interactions (face-to-face and free play) when children were 6, 12, 18, and 57-months-old in fullterm (37-41 weeks, >2500 g; n = 48) and healthy VLBW/PT (26-32 weeks gestation, birth weight 800-1500 g, corrected for gestational age; n = 61) children. Developmental trajectories of maternal and child EA were assessed using multilevel growth modeling in Mplus. Results indicated that, even after controlling for maternal EA, there was a persistent negative effect of VLBW/PT birth status on child EA trajectories. Both initially and over time, VLBW/PT infants lagged behind their fullterm counterparts on levels of responsiveness and involvement with mothers. There was also a persistent positive effect of maternal EA (sensitivity and structuring) on child EA trajectories. Higher average levels of maternal sensitivity and structuring across time were also associated with higher and persistent levels of child responsiveness and involvement of their mothers. Importantly, results held after modeling both effects together, and after controlling for maternal education and child gender. Our results have implications for VLBW/PT children's development, the parent-child relationship, and integrating family level factors and relationship dimensions in early prevention and intervention programs.

Abstract
Theory underscores the importance of parenting in sleep development, but few studies have examined whether links vary by temperament. To address this gap, we tested whether potential links between early maternal sensitivity and early adolescent sleep problems varied by child negative emotionality and delay of gratification. Using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 820), we found that high maternal sensitivity predicted fewer bedtime problems and longer sleep duration at 6th grade for toddlers with high negative emotionality, whereas low maternal sensitivity predicted the reverse. No differences were observed for low negative emotionality. Moreover, delay of gratification predicted fewer bedtime problems at 6th grade, but did not moderate associations between maternal sensitivity, negative emotionality, and sleep. Findings demonstrate that high, but not low, negative emotionality renders toddlers differentially susceptible and receptive to maternal sensitivity in relation to sleep.

Abstract
The current study prospectively examined the ways in which goodness of fit between maternal and infant sleep contributes to maternal depressive symptoms and the mother-child relationship across the first years of life. In a sample of 173 mother-child dyads, maternal prenatal sleep, infant sleep, maternal depressive symptoms, and mother-child attachment security were assessed via self-report, actigraphy, and observational measures. Results suggested that a poor fit between mothers' prenatal sleep and infants' sleep at 8 months (measured by sleep diary and actigraphy) was associated with maternal depressive symptoms at 15 months. Additionally, maternal depression mediated the association between the interplay of mother and infant sleep (measured by sleep diary) and mother-child attachment security at 30 months. Findings emphasize the importance of the match between mother and infant sleep on maternal wellbeing and mother-child relationships and highlight the role of mothers' perceptions of infant sleep.

Abstract
OBJECTIVES To evaluate the effects of behavioral interventions on the sleep/wakefulness of infants, parent and infant stress, and later child emotional/behavioral problems, and parent-child attachment. METHODS A total of 43 infants (6-16 months, 63% girls) were randomized to receive either graduated extinction (n = 14), bedtime fading (n = 15), or sleep education control (n = 14). Sleep measures included parent-reported sleep diaries and infant actigraphy. Infant stress was measured via morning and afternoon salivary cortisol sampling, and mothers' self-reported mood and stress. Twelve months after intervention, mothers completed assessments of children's emotional and behavioral problems, and mother-child dyads underwent the strange situation procedure to evaluate parent-child attachment. RESULTS Significant interactions were found for sleep latency (P < .05), number of awakenings (P < .0001), and wake after sleep onset (P = .01), with large decreases in sleep latency for graduated extinction and bedtime fading groups, and large decreases in number of awakenings and wake after sleep onset for the graduated extinction group. Salivary cortisol showed small-to-moderate declines in graduated extinction and bedtime fading groups compared with controls. Mothers' stress showed small-to-moderate decreases for the graduated extinction and bedtime fading conditions over the first month, yet no differences in mood were detected. At the 12-month follow-up, no significant differences were found in emotional and behavioral problems, and no significant differences in secure-insecure attachment styles between groups. CONCLUSIONS Both graduated extinction and bedtime fading provide significant sleep benefits above control, yet convey no adverse stress responses or long-term effects on parent-child attachment or child emotions and behavior.

Abstract
Many scholars have proposed that parent-child attachment security should favor child sleep. Research has yet, however, to provide convincing support for this hypothesis. The current study used objective measures of sleep and attachment to assess the longitudinal links between mother-child attachment security and subsequent sleep, controlling for child dependency. Sixty-two middle-class families (30 girls) were met twice, when children were 15 months (Wave 1; W1) and 2 years of age (Wave 2; W2). At W1, mother-child attachment was assessed with the observer version of the Attachment Q-Sort. At W2, children wore an actigraph monitor for 72 hr. Results indicated that children more securely attached to their mothers subsequently slept more at night and had higher sleep efficiency, and these predictions were not confounded by child dependency. These findings suggest a unique role for secure attachment relationships in the development of young children's sleep regulation, while addressing methodological issues that have long precluded consensus in this literature.

Abstract
The ABCs of SLEEPING mnemonic was developed to serve as an organizing framework for common pediatric sleep recommendations. The mnemonic stands for 1) age appropriate bedtimes and wake-times with consistency, 2) schedules and routines, 3) location, 4) exercise and diet, 5) no electronics in the bedroom or before bed, 6) positivity 7) independence when falling asleep and 8) needs of child met during the day, 9) equal great sleep. This review examines the empirical evidence behind the practices and recommendations captured by the ABCs of SLEEPING mnemonic for children aged 1 to 12. A search was conducted of key electronic databases (PubMed, PsycINFO, CINAHL, & EMBASE) to identify English articles that included the concepts of sleep, insomnia, and/or bedtime. 77 articles were eligible for inclusion and were coded to extract key details and findings regarding the relations between sleep practices identified in the ABCs of SLEEPING mnemonic and sleep outcomes. Findings provided preliminary support for many of the recommendations that are commonly made to families regarding healthy sleep practices. However, more robust investigations are needed to better understand the causal contributions of healthy sleep practices to the onset and maintenance of children's sleep problems.

Rem sleep, early experience, and the development of reproductive strategies. HUMAN NATURE-AN INTERDISCIPLINARY BIOSOCIAL PERSPECTIVE 2015; 13:405-35.

Abstract
We hypothesize that rapid eye movement or REM sleep evolved, in part, to mediate sexual/reproductive behaviors and strategies. Because development of sexual and mating strategies depends crucially on early attachment experiences, we further hypothesize that REM functions to mediate attachment processes early in life. Evidence for these hypotheses comes from (1) the correlation of REM variables with both attachment and sexual/reproductive variables; (2) attachment-related and sex-related hormonal release during REM; (3) selective activation during REM of brain sites implicated in attachment and sexual processes; (4) effects of maternal deprivation on REM; (5) effects of REM deprivation on sexual behaviors; and (6) the REM-associated sexual excitation. To explain why we find associations among REM sleep, attachment, and adult reproductive strategies, we rely on recent extensions of parent-offspring conflict theory. Using data from recent findings on genomic imprinting, Haig (2000) and others suggest that paternally expressed genes are selected to promote growth of the developing fetus/child at the expense of the mother, while maternally expressed genes counter these effects. Because developmental REM facilitates attachment-related outcomes in the child, developmental REM may be regulated by paternally expressed genes. In that case, REM may have evolved to support the "aims" of paternal genes at the expense of maternal genes.

Abstract
Infant sleep is a common concern for new parents. Although many expect a newborn infant to wake frequently, encouraging a baby to sleep through the night by a few months of age is seen as both a developmental aim and a parenting success. Many new mothers believe that their infants' diet is related to their sleep; formula milk or increased levels of solid food are often given in an attempt to promote sleep. However, the impact of these in later infancy is not understood. In the current study 715 mothers with an infant 6-12 months of age reported their infants' typical night wakings and night feeds alongside any breastfeeding and frequency of solid meals. Of infants in this age range, 78.6% still regularly woke at least once a night, with 61.4% receiving one or more milk feeds. Both night wakings and night feeds decreased with age. No difference in night wakings or night feeds was found between mothers who were currently breastfeeding or formula feeding. However, infants who received more milk or solid feeds during the day were less likely to feed at night but not less likely to wake. The findings have important implications for health professionals who support new mothers with infant sleep and diet in the first year. Increasing infant calories during the day may therefore reduce the likelihood of night feeding but will not reduce the need for parents to attend to the infant in the night. Breastfeeding has no impact on infant sleep in the second 6 months postpartum.

Abstract
Infant and toddler regulatory problems (RPs) including crying, sleeping and feeding, are a frequent concern for parents and have been associated with negative behavioral outcomes in early and middle childhood. Uncertain is whether infant and toddler RPs predict stable, trait-like dysregulated behavior across childhood. We addressed this gap in the literature using data from the Avon Longitudinal Study of Parents and Children (ALSPAC). RPs at 6, 15-18, & 24-30 months and childhood dysregulated behavior at 4, 7, 8, & 9.5 years were assessed using mother report. Latent Class Growth Analysis (LCGA) indicated that trajectories of childhood dysregulated behavior were stable over time. All single RPs (i.e., crying, sleeping & feeding problems) were significantly associated with childhood dysregulated behavior. For example, crying problems at 6 months after controlling for confounders (Odds Ratios; 95% Confidence Intervals): Moderate dysregulated behavior: OR = 1.50, 95% CI [1.09 to 2.06], high dysregulated behavior: OR = 2.13, 95% CI [1.49 to 3.05] and very high dysregulated behavior: OR = 2.85, 95% CI [1.64 to 4.94]. Multiple RPs were especially strongly associated with dysregulated behavior. For example, the RP composite at 15-18 months: 1 RP, very high dysregulated behavior: OR = 2.79, 95% CI [2.17 to 3.57], 2 RPs, very high dysregulated behavior: OR = 3.46, 95% CI [2.38 to 5.01], 3 RPs, very high dysregulated behavior: OR = 12.57, 95% CI [6.38 to 24.74]. These findings suggest that RPs in infants and toddlers predict stable dysregulated behavior trajectories across childhood. Interventions for early RPs could help prevent the development of chronic, highly dysregulated behavior.

Abstract
The majority of studies on child sleep problems focus primarily on mothers, neglecting paternal influences. Guided by the transactional framework, we explored how child temperament, paternal and maternal stress, and the parent-child interactions differ between families having children with sleep disturbances and a selected comparison group. The role of paternal involvement in child caregiving as a moderator of these differences was assessed. The sample consisted of 51 children (1-3 years old) and their mothers and fathers. Data were collected during home visits, when mothers and fathers completed questionnaires and were interviewed. In addition, mother-child and father-child interactions were videotaped. Results indicate that compared to the comparison group, fathers rated children with sleep disturbances as fussier, both their mothers and fathers experienced higher levels of stress, and reported using more bedtime interactions that interfere with child's sleep-wake self-regulation. In addition, their fathers were less sensitive during father-child interaction and less involved in child caregiving. Finally, paternal involvement moderated the group differences seen in maternal stress, suggesting that high paternal involvement acted as a buffer to protect parents of children with sleep disturbances from experiencing parental stress. The important role of fathers in families having children with sleep disturbances is discussed.

Abstract
Relatively little is known about nightmares and other forms of disturbed dreaming in children. This article reviews the literature on the prevalence and correlates of nightmares in children and highlights key methodological issues in the field. Results show that regardless of how they are defined and measured, nightmares affect a significant proportion of children of all ages and there is some evidence to suggest that nightmare frequency may peak around the age of 10. Gender differences in nightmare frequency, with girls reporting more nightmares than do boys, tend to appear between the ages of 10 and 15. Although nightmares are associated with a range of psychosocial difficulties (e.g., stress, behavioural problems), elevated anxiety and concomitant sleep-related disorders (e.g., sleepwalking) are among the most robust correlates of nightmares. Very few studies have examined nightmare treatment in children, but promising results have been obtained with imagery rehearsal therapy. Overall, research in the field has been hampered by inconsistent definitions for nightmares, by extensive variability in questionnaire items used to measure nightmare frequency, and by a lack of awareness of how using parents versus children as respondents may impact results. Longitudinal studies are needed to better understand how nightmares and their correlates evolve during childhood and adolescence, to delineate their clinical significance, and to develop effective and age-appropriate treatment strategies.

Abstract
PURPOSE Review infant sleep research with a focus on understanding the elements related to infant safety and infant and maternal well-being during nighttime care. DATA SOURCES This review summarizes current research and addresses the controversies and conflicting outcomes reported in infant nighttime care. This review addresses current literature on infant sleep patterns, as well as factors that influence infant sleep and are consequences of different care routines. Conversation points are provided to help nurse practitioners (NPs) address safety and practice concerns. CONCLUSIONS Shared information can help parents provide a safe and healthy environment for infants and help to facilitate communication ties between the healthcare providers and the families. IMPLICATIONS FOR PRACTICE NPs need to help parents understand infant sleep patterns norms, what is current knowledge about infant nightwakings and parental presence, as well as about approaches to altering infant sleep patterns. Integrating this knowledge with parent preferences that are influenced by cultural practices and individual differences is crucial in helping parents develop a strong sense of competence and comfort with their choices and behaviors.

Abstract
Based on early life experiences in which developmental, genetic, and environmental components interact, humans learn to trust themselves and others and connect emotionally in consistent ways that are broadly defined as "attachment styles." These relatively stable patterns of interpersonal interaction are associated with either vulnerability to various health risks or resilience. Similarly, the mechanisms involved in sleep regulation undergo developmental changes that overlap temporally with attachment formation and remain sensitive to a series of biological, environmental and psychological influences. Interestingly, while sleep has been conceptualized as a fundamental attachment behavior given its dyadic context, few studies have explored its relationship with attachment style in various ages. We present the first systematic review of the published literature examining the relationship between attachment style and sleep in humans across the life span. While levels of evidence and methods of assessment vary significantly, the results suggest a possible life-long relationship between individual attachment style and sleep. These findings are particularly useful in understanding relatively ingrained psychological mechanisms that can affect and be affected by sleep. Clinical and research implications are discussed.

Abstract
AIM To characterize mother-child interaction in children with suspected gastrointestinally manifested cow's milk allergy (GI-CMA) and to explore factors associated with the parentally perceived symptoms. METHODS We invited a randomly selected group of children with suspected GI-CMA and their mothers to take part in a video recording of them playing together. The mother-child interaction was rated using the Emotional Availability Scales (EAS, 4th edition) and compared with national normative data. RESULTS Video recordings were conducted with 24 patients (15 girls and nine boys) with a median age of 10.1 months (range 2.1-20.5 months) undergoing a double-blind, placebo-controlled food challenge for cow's milk allergy. The EAS profile in the challenge negative group (17/24) was significantly different from the normative data. The scores for maternal sensitivity (p = 0.0049) and nonintrusiveness (p = 0.0192), together with child responsiveness (p = 0.0053) and involvement of mother (p = 0.0085), were all significantly lower when compared to the normative data. The dimensions of maternal nonhostility and structuring, as well as the scores of the challenge positive group, did not differ from the normative data. CONCLUSION Dysfunctional mother-child emotional interaction was frequent in young children with suspected GI-CMA ruled out by the cow's milk challenge. Appropriate psychological support should be considered.

Abstract
The present study explores behavioral and sleep outcomes in preschool-age siblings of children with autism spectrum disorders (ASD). This study focuses on behavior problems that are common in children with ASD, such as emotional reactivity, anxiety, inattention, aggression, and sleep problems. Infant siblings were recruited from families with at least one older child with ASD (high-risk group, n = 104) or families with no history of ASD (low-risk group, n = 76). As part of a longitudinal prospective study, children completed the Mullen Scales of Early Learning and the Autism Diagnostic Observation Schedule, and parents completed the Child Behavior Checklist (CBCL) and the Social Communication Questionnaire at 36 months of age. This study focuses on developmental concerns outside of ASD; therefore, only siblings who did not develop an ASD were included in analyses. Negative binomial regression analyses revealed that children in the high-risk group were more likely to have elevated behavior problems on the CBCL Anxious/Depressed and Aggression subscales. To explore sleep problems as a correlate of these behavior problems, a second series of models was specified. For both groups of children, sleep problems were associated with elevated behavior problems in each of the areas assessed (reactivity, anxiety, somatic complaints, withdrawal, attention, and aggression). These findings support close monitoring of children with a family history of ASD for both behavioral and sleep issues.

Abstract
The use of actigraphs, or ambulatory devices that estimate sleep-wake patterns from activity levels, has become common in pediatric research. Actigraphy provides a more objective measure than parent-report, and has gained popularity due to its ability to measure sleep-wake patterns for extended periods of time in the child's natural environment. The purpose of this review is: 1) to provide comprehensive information on the historic and current uses of actigraphy in pediatric sleep research; 2) to review how actigraphy has been validated among pediatric populations; and 3) offer recommendations for methodological areas that should be included in all studies that utilize actigraphy, including the definition and scoring of variables commonly reported. The poor specificity to detect wake after sleep onset was consistently noted across devices and age groups, thus raising concerns about what is an "acceptable" level of specificity for actigraphy. Other notable findings from this review include the lack of standard scoring rules or variable definitions. Suggestions for the use and reporting of actigraphy in pediatric research are provided.

Abstract
In this report changes and stability in sleep-wake characteristics, at the latter part of infancy, were examined. The sample comprised of 34 healthy infants whose sleep was assessed by means of actigraphy at 8, 10, 12 and 14 months. The results indicated that while sleep schedules did not change significantly from 8 to 14 months, sleep consolidation continued across time. Age 12 months stands out in that sleep disruption was unrelated to whether or not the child was a frequent nightwaker before and/or after the 1st birthday. The findings demonstrate the importance of investigating sleep longitudinally using multiple time scales.

Abstract
OBJECTIVE : Night wakings are common in infancy. Although a link between infant night wakings and attachment to the primary caregiver has been previously proposed, empirical support is limited so far. The aim of this longitudinal study was to examine the early history of night waking in infants who were later classified as securely or insecurely (avoidantly, resistantly, or disorganized) attached. METHODS : Participants in the study were 193 infants and their mothers. Information on infant night wakings was collected with the use of daily sleep diaries for the first 6 months of life and again for 2 weeks at 12 months of age. Infant-mother attachment was assessed using the Strange Situation (Ainsworth et al, Patterns of Attachment: A Psychological Study of the Strange Situation. New York: Hillsdale; 1978) when the infants were 12 months of age. RESULTS : Longitudinal regression analyses showed that, after controlling for many covariates, infants with an insecure-resistant attachment at 12 months of age awoke more during the night in their first 6 months of life than the other infants. Furthermore, infants with different attachment classifications developed different patterns of night wakings over the first 6 months, with the insecure-avoidant infants waking the least toward the end of the 6 months. Hierarchical multiple regression analyses showed no associations between attachment and night wakings at 12 months of age. CONCLUSION : This study is the first in showing that attachment at 12 months of age is related to infant night waking patterns in the first 6 months of life. Patterns of infant night wakings early in life apparently reflect the emerging attachment relationship.

Abstract
BACKGROUND We examined longitudinal relations between children's sleep and their emotional security in the mother-child, father-child, and parental marital relationships, with the goal of explicating the direction of association over time. Gender-related effects were also examined. METHOD Sleep duration was examined through actigraphy, and sleep quality was assessed via both actigraphy and self-reports. Children were in 3rd (T1) and 5th (T2) grades. The sample was composed of 78 boys and 98 girls at T1, and 62 boys and 80 girls at T2. RESULTS Security in the child-mother, child-father, and marital relationships at T1 were predictive of sleep problems two years later even after controlling for children's sleep at T1. CONCLUSIONS Collectively, results were more supportive of security predicting sleep parameters than the other direction of effects. Results highlight the important associations between family functioning and children's sleep, and extend the literature through the longitudinal design.

Abstract
This study examined associations between mother-infant nighttime interactions and mother-infant attachment when infants were 12 months old. Forty-four mother-infant pairs participated in this study. For three consecutive nights at home, babies were observed in their cribs using a digital video system. Mothers reported on their nighttime interactions with their babies using a self-report diary and completed a questionnaire regarding child temperament. Attachment was assessed in the Strange Situation (Ainsworth, Blehar, Waters, & Wall, 1978). Mothers of securely attached infants had nighttime interactions that were generally more consistent, sensitive and responsive than those of insecurely attached infants. Specifically, in secure dyads, mothers generally picked up and soothed infants when they fussed or cried after an awakening.

Abstract
Infant sleep undergoes dramatic evolution during the first year of life. This process is driven by underlying biological forces but is highly dependent on environmental cues including parental influences. In this review the links between infant sleep and parental behaviors, cognitions, emotions and relationships as well as psychopathology are examined within the context of a transactional model. Parental behaviors, particularly those related to bedtime interactions and soothing routines, are closely related to infant sleep. Increased parental involvement is associated with more fragmented sleep. Intervention based on modifying parental behaviors and cognitions have direct effect on infant sleep. It appears that parental personality, psychopathology and related cognitions and emotions contribute to parental sleep-related behaviors and ultimately influence infant sleep. However, the links are bidirectional and dynamic so that poor infant sleep may influence parental behaviors and poor infant sleep appears to be a family stressor and a risk factor for maternal depression.

Abstract
This review paper presents and places in context findings from 23 manuscripts based on the data sets of the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (SECCYD). The NICHD study tracked the development of more than 1000 children from birth through age 15. The children were born across the USA to families that were diverse in terms of their economic, educational, and ethnic background. The children also varied in terms of the timing, extent, quality, and type of their child care experiences. The findings reported in this review paper pertain to (1) predictors of child-mother attachment; (2) links between child-mother attachment and children's developmental outcomes; and (3) methods for assessing attachment. The review paper also includes suggestions for future attachment research afforded by the data sets of the NICHD SECCYD. Not all the hypotheses tested in the reviewed papers were confirmed, and those that were confirmed were associated with modest effect sizes. Some findings emerged under specific conditions, even though they were expected to be more universal. These findings need to be discussed and aligned with theory. Also, the extent to which the findings generalize beyond the historical period and the country in which the data were collected merits discussion and exploration.

Abstract
PURPOSE Chronic illness in infancy may influence parent-infant interaction. We assessed quality of mother-infant interaction in children with esophageal atresia (EA) and searched for predictors for impaired interaction. METHODS The study group comprised 37 one-year-old infants with EA born in 1999 to 2002 and their mothers. A comparison group comprised 10 infants with urologic problems without feeding difficulties and their mothers. Parent Child Early Relational Assessment was used to assess mother-child interaction in feeding and play situation. General Health Questionnaire and State Trait Anxiety Inventory were used to assess maternal psychological distress and anxiety. RESULTS Many aspects of mother-EA infant interaction showed strength. However, mothers of EA children were compared to control-mothers significantly influenced in their ability to interact and the EA-mothers' "positive affective involvement, sensitivity, and responsiveness" during feeding was in range of concern. Small but significant effect of the mother's feeling of incompetence on their interaction was found. CONCLUSION Mothers' attitude during feeding was negatively influenced in interaction between mother and infant with EA. The results suggest possibility for improvement in mother infant interaction by enhancing mothers' welfare when caring for infants with EA in medical services.

Abstract
BACKGROUND The regulation of infants' sleep is determined not only by biological factors but by relational aspects too. This study focused on maternal separation anxiety and examined its association with sleep-wake regulation at 10 months of age. METHOD In a community sample comprising 52 infants and their mothers, sleep was measured objectively with an activity monitor, as well as through questionnaires. The mothers reported on their own separation anxiety and on the child's perceived distress. RESULTS The main finding was that maternal separation anxiety was linked to settling to sleep routines and to night-waking. The contribution of the mothers' own separation anxiety to their infants' night-waking remained significant after controlling for the child's fussiness. CONCLUSIONS Consistent with the transactional perspective, the current research documented an interplay between maternal separation anxiety and aspects of the child's sleep-wake transitions.

Abstract
PURPOSE To describe the effect of nursing caregiving on infant sleep-wake states by gender in preterm infants. DESIGN Descriptive measures at 34 weeks postmenstrual age and at discharge. SAMPLE Twenty-two hospitalized preterm infants. MAIN OUTCOME VARIABLE Infant state and caregiving episodes were coded in 15-second intervals from video recordings of approximately three hours duration. Time plots of state and caregiving were analyzed visually to summarize spontaneous state changes and state change associated with caregiving. RESULTS Sleep and wake state distribution did not differ statistically by gender; however, the rate of state change in male infants was twice that of females (p=.012) at discharge. At discharge, male infants received approximately twice as many care episodes as females. At discharge, the rate of state change in response to caregiving in male infants was four times that of female infants (p=.026). Males exhibited a greater percentage of caregiving episodes related to state change than did females at discharge (p=.018). Findings suggest further exploration of possible gender differences in state regulation and state change in response to caregiving.

Abstract
BACKGROUND Experimental animal data link prenatal stress with sleep disturbance in offspring, but the link in humans is unclear. AIMS To investigate the link between prenatal maternal anxiety and depression and infant sleep disturbance from 6 to 30 months of age. STUDY DESIGN Longitudinal prospective study of a large birth cohort from pregnancy to 30 months. Questionnaire measures of anxiety and depression were completed by mothers at 18 and 32 weeks gestation and at 8 weeks and 8 months postpartum. SUBJECTS The ALSPAC cohort, a prospective community study of women in the UK who have been followed since pregnancy. OUTCOME MEASURES Measures of total sleep time, number of awakenings, and broadly defined sleep problems were available on children at ages 6, 18, and 30 months. RESULTS Reliable measures of total sleep time, nighttime awakenings, and sleep problems were identified at 6, 18, and 30 months. Higher levels of prenatal maternal anxiety and depression predicted more sleep problems at 18 and 30 months, after controlling for postnatal mood and obstetric and psychosocial covariates; the association was not restricted to clinical extremes. No link with total sleep time was observed. CONCLUSIONS Mood disturbance in pregnancy has persisting effects on sleep problems in the child, a finding that is consistent with experimental animal research. The findings add to a growing literature showing that maternal prenatal stress, anxiety, and depression may have lasting effects on child development.

Abstract
OBJECTIVE In this study we addressed the association between two major achievements of infancy: independent locomotion and 'sleeping through the night'. METHODS Mothers of 107 healthy infants aged between five and eight months completed a sleep questionnaire and a motor checklist. RESULTS AND CONCLUSIONS Infants who were already crawling had more bedtime difficulties and nightwaking than did pre-crawlers. Among 7- and 8-month-old infants, locomotion predicted 17% of nightwaking variance, after controlling for age and gender. In discussing the developmental implications of locomotion we suggest that crawling may not only 'broaden the mind' but also 'cost' sleep. More studies, across time, on how motor development and sleep-wake regulation interrelate are recommended.

Abstract
This study examined the association between sleep-wake patterns and achievements on the Bayley Scales of Infant Development, in a low-risk sample of 10-month-olds. The sleep of 50 infants was recorded at home by means of a small activity monitor (actigraph). More motor activity in sleep and more fragmented sleep pattern were moderately associated with lower mental developmental index (MDI) scores. The psychomotor developmental index (PDI) was not associated with the sleep characteristics. The finding that at the end of the first year, sleep quality accounted for a significant, albeit small, percentage of the cognitive achievement variance is in line with a model that links sleep-wake states and behavior regulation during arousal.
