Effect of soothing techniques on infants’ self‐regulation behaviors (sleeping, crying, feeding): A randomized controlled study

The Effects of Baby Calming Training Provided to Primiparous Mothers on Maternal Role Perception, Maternal Attachment, and Breastfeeding Self-Efficacy: A Randomized Controlled Trial

Background: Mothers of crying babies have difficulty adapting to their roles and problems with breastfeeding and attachment. Objective: This study aimed to assess the impact of the baby calming training provided to primiparous mothers on maternal role perception, maternal attachment, and breastfeeding self-efficacy. Methods: The study was conducted in a randomized controlled experimental design between March 2023 and March 2024 in the gynecology and obstetrics services of a public hospital in northeastern Turkey (Clinical Trial Number: NCT05594836). The research was conducted with a total of 84 primiparous mothers, including 41 intervention and 43 control groups, who met the inclusion criteria. The Baby Calming Training was administered face-to-face in the intervention group, utilizing a baby swaddling blanket, a sleep companion emitting white noise, and a training booklet. The control group received routine care. Data were collected through the Mother and Baby Introductory Information Form, Semantic Difference Scale-Me as a Mother, Maternal Attachment Inventory, Breastfeeding Self-Efficacy Scale-Short Form, and Infant Sleep Activity Record. The data were analyzed using descriptive statistics, Pearson's chi-square test, independent samples t-test, Mann-Whitney U test, Wilcoxon test, mixed design ANOVA analysis, Cohen's d, and 95% confidence interval (CI). This study adhered to CONSORT research guidelines. Results: Mothers in the intervention group exhibited higher mean scores on the perception of maternal role (mean ± SD: 70.37 ± 5.92, t: 8.590, 95% confidence interval [CI]: [1.347-2.375], d: 1.865, p < 0.001), maternal attachment (mean ± SD: 100.42 ± 1.52, U: 151.500, 95% CI: [0.732-0.892], d: 0.828, p < 0.001), and breastfeeding self-efficacy (mean ± SD: 64.00 ± 5.98, t: 8.109, 95% CI: [1.248-2.258], d: 1.757, p < 0.001) than the control group. It was determined that the total sleep time of the babies in the intervention group was higher, and the total crying duration was lower (p < 0.001). Conclusion: The study revealed that infant soothing training for primiparous mothers enhanced maternal role perception, maternal attachment, breastfeeding self-efficacy, and extended infants' sleep duration. Furthermore, infants exhibited reduced crying.

Regulatory problems and associated factors among infants in Arba Minch health and demographic surveillance system sites, southern Ethiopia

INTRODUCTION

Infant regulatory problems are a common source of concern for parents, and they increase the risk of impaired infant-caregiver bonding. Despite their impact, they are often overlooked in Ethiopia. Hence, this study aimed to determine the prevalence and associated factors of infant regulatory problems in Arba Minch Health and Demographic Surveillance System sites in southern Ethiopia.

METHODS

A community-based cross-sectional study was conducted among 451 mother-infant pairs from February 15 to March 15, 2022. Regulatory problems were assessed using diagnostic interviews for regulatory problems. The data was collected using an open data kit Android application and analyzed with Stata version 17.0. Bivariable and multivariable logistic regression analyses were computed to identify factors associated with each infant regulatory problem. Statistical significance was declared at a p-value < 0.05.

RESULTS

In this study, four hundred forty-nine mother-infant pairs were involved, with a response rate of 99.5%. The prevalence of excessive crying, feeding problems, and sleeping difficulties was 14.03% [95% CI: 10.95, 17.59], 20.04% [95% CI: 16.44, 24.05], and 13.59% [95% CI: 10.55, 17.11], respectively. Attending primary education (AOR: 2.54, 95% CI: 1.22, 5.32), high perceived social support (AOR: 0.32, 95% CI: 0.12, 0.89), feeding problems (AOR: 5.0, 95% CI: 2.65, 9.45), and depression, anxiety, and stress (DAS) symptoms (AOR: 2.67, 95% CI: 1.19, 5.98) were associated with excessive crying. In addition, a family size of above five (AOR: 1.82, 95% CI: 1.03, 3.22), excessive crying (AOR: 3.76, 95% CI: 1.85, 7.65), sleeping problems (AOR: 2.29, 95% CI: 1.13, 4.65), comorbid DAS symptoms (AOR: 3.42, 95% CI: 1.64, 7.11), alcohol abuse (AOR: 1.89, 95% CI: 1.04, 3.42), and late initiation of complementary feeding (AOR: 2.67, 95% CI: 1.22, 5.88) were associated with feeding problems. Furthermore, attending primary education (AOR: 2.35, 95% CI: 1.16, 4.77), feeding problems (AOR: 3.47, 95% CI: 1.86, 6.48), and comorbid DAS symptoms (AOR: 3.23, 95% CI: 1.53, 6.84) were associated with sleeping problems.

CONCLUSIONS

Approximately one-third of infants encountered at least one regulatory problem. Level of education, perceived social support, feeding problems, and DAS symptoms were associated with excessive crying. Large family sizes, excessive crying, sleeping problems, comorbid DAS symptoms, alcohol abuse and, late initiation of complementary feeding increase the likelihood of feeding problems. Moreover, attending primary education, feeding problems, and comorbid DAS symptoms increase the odds of sleeping problems. Continuous guidance and support on infant soothing techniques, cognitive and behavioral therapy, and counselling on appropriate coping strategies for postpartum women are imperative to reduce the burden of infant regulatory problems.

From co-regulation to self-regulation: Maternal soothing strategies and self-efficacy in relation to maternal reports of infant regulation at 3 and 7 months

This study, conducted in Germany, examines the role of maternal soothing strategies to explain the association of maternal self-efficacy with infant regulation (crying and sleeping behavior). Questionnaire data of 150 mothers, living in Germany, with mixed ethnic and educational backgrounds were collected when infants were 3 and 7 months old. Two types of maternal soothing strategies were distinguished: close soothing, involving close physical and emotional contact, and distant soothing, involving physical and emotional distancing from the infant. A cross-sectional SEM at 3 months indicated that maternal self-efficacy is associated with reported infant regulation through distant soothing strategies. Low maternal self-efficacy was associated with frequent maternal use of distant soothing, which in turn was related to reported infant regulation problems, that is, non-soothability and greater crying frequency. Frequent use of close soothing was associated with reported infant sleeping behavior, that is, frequent night-time awakenings. A longitudinal SEM further indicated that the effects of close soothing persisted at least until the infants' age of 7 months. The study showed how low maternal self-efficacy, increased use of distant soothing, and reported early infant regulation problems are intertwined and that, due to their persisting positive effect on infant soothability, close soothing better supports infant development.

Parental Discontent with Infant Sleep During the First Two Years of Life

BACKGROUND

Problematic sleep in infants can have a high impact on families. We examined parental discontent with infant sleep in the first six months of life and parent-perceived problematic sleep during the second year of life.

METHODS

We used Sarphati Cohort data of 1471 children. During periodic youth health care visits in the first six months of life, professionals registered parental discontent with infant sleep. In the second year of life, parents filled out the Brief Infant Sleep Questionnaire (BISQ), from which we defined parent-perceived problematic sleep and BISQ-defined problematic sleep. We examined the association of parental discontent with infant sleep during the first six months with both BISQ-derived outcomes up to age two, using multivariable logistic regression analysis.

RESULTS

26% of parents were discontented with infant sleep during the first six months of life. During the second year of life, 27% of the parents perceived their child's sleep as problematic, and 9% of the infants had BISQ-defined problematic sleep. Early parental discontent with infant sleep was associated with parent-perceived problematic sleep [adjusted OR 2.50 (95% CI 1.91-3.28)], and BISQ-defined problematic sleep [adjusted OR 1.88 (1.11-3.17)].

CONCLUSIONS

Early registered parental discontent with infant sleep was a predictor of parent-perceived problematic sleep in early toddlerhood. Registering parental discontent during infancy might enable professionals to identify a group of infants at risk for later problematic sleep. We recommend screening and parental support for sleep difficulties in an early stage.

The impact of swaddling upon breastfeeding: A critical review

INTRODUCTION

Many parents swaddle their infants to promote sleep and reduce night-waking, however lack of definitive evidence about the pros and cons of swaddling when breastfeeding hinders postnatal recommendations regarding this infant care practice. This review critically examines research conducted on the impact of swaddling upon breastfeeding.

METHODS

Only two recent studies on swaddling outcomes have reported infant feed-type, therefore the purpose of this paper is to consider the known effects of swaddling on breastfeeding babies and their mothers. We interpret the existing literature on swaddling in terms of impact on breastfeeding physiology and behaviour during the immediate post-natal period, and as infancy progresses.

RESULTS

Infants swaddled immediately after birth show a delay in initial breastfeeding, less successful suckling at the breast, reduced intake of breastmilk and greater weight loss compared to un-swaddled babies. Swaddling visually obscures feeding cues and reduces crying, thereby eliminating two key feeding prompts typically used by parents/carers.

CONCLUSIONS

As swaddled babies cry less, and are fed less frequently than un-swaddled babies some clinical trials position swaddling as a 'novel weight regulation tool' to combat obesity. However, in the case of breastfed babies, by reducing feed frequency swaddling may impede maternal milk production and thereby infant growth.

The need of having a plan in excessive infant crying - A qualitative study of parents' experiences of healthcare support

AIM

Excessive infant crying increases parents' concerns regarding their infant's health and the burden of parenting. We aimed to gain insight into the healthcare support needs of parents with excessively crying infants.

METHODS

An exploratory qualitative study was conducted in the Netherlands. We performed semi-structured interviews with parents of 12 infants between June and December 2020, followed by inductive and deductive thematic analysis.

RESULTS

Parents described what their needs were with regard to the assessment of infant crying and support by professionals. Long-lasting crying made parents feel that there must be a somatic cause. If they could soothe their infant, they gained more confidence that their infant was healthy. We identified four interrelated themes: (i) confidence in the professional; (ii) seeking a somatic cause for the crying; (iii) seeking acknowledgment; and (iv) exhaustion of parents and feelings of failure.

CONCLUSION

Parental support needs were best fulfilled by professionals who took them seriously, demonstrated medical expertise, and offered a practical plan. Perinatal parental education on normal infant behaviour and infant soothing techniques might improve parental self-efficacy at an early stage and prevent medicalization of excessive crying.

Relations between bedtime parenting behaviors and temperament across 14 cultures

Objectives

The present study examined parental sleep-supporting practices during toddlerhood in relation to temperament across 14 cultures. We hypothesized that passive sleep-supporting techniques (e.g., talking, cuddling), but not active techniques (e.g., walking, doing an activity together), would be associated with less challenging temperament profiles: higher Surgency (SUR) and Effortful Control (EC) and lower Negative Emotionality (NE), with fine-grained dimensions exhibiting relationships consistent with their overarching factors (e.g., parallel passive sleep-supporting approach effects for dimensions of NE).

Methods

Caregivers (N = 841) across 14 cultures (M = 61 families per site) reported toddler (between 17 and 40 months of age; 52% male) temperament and sleep-supporting activities. Utilizing linear multilevel regression models and group-mean centering procedures, we assessed the role of between- and within-cultural variance in sleep-supporting practices in relation to temperament.

Results

Both within-and between-culture differences in passive sleep-supporting techniques were associated with temperament attributes, (e.g., lower NE at the between-culture level; higher within-culture EC). For active techniques only within-culture effects were significant (e.g., demonstrating a positive association with NE). Adding sleep-supporting behaviors to the regression models accounted for significantly more between-culture temperament variance than child age and gender alone.

Conclusion

Hypotheses were largely supported. Findings suggest parental sleep practices could be potential targets for interventions to mitigate risk posed by challenging temperament profiles (e.g., reducing active techniques that are associated with greater distress proneness and NE).

Infant sleep as a topic in healthcare guidance of parents, prenatally and the first 6 months after birth: a scoping review

Background

This scoping review focuses on infant sleep-related factors and themes that are relevant when health practitioners provide preventive health services to expectant and new parents.

Methods

A systematic literature search in CINAHL, PubMed, and PsycINFO, published in 2010 or later, identified 1661 records. The search was further narrowed to focus on sleep in healthy term-born infants until the second half of the first year of life. A blinded review by both authors covered 136 papers, of which 43 papers were reviewed in the full text. Finally, 38 articles were included in the data extraction.

Results

The analysis process showed that the selected studies formed three main information categories: 11 studies thematised safe infant sleep issues, 10 studies described design and findings from sleep-related intervention studies, and 17 studies focused on different parent-child interactive aspects that may influence the quality and duration of infant sleep in the first six months of life.

The main finding is that knowledge about early infant sleep is very complex, and includes both child, parent, and environmental factors. Several studies have shown that the concepts and factors related to safe infant sleep also influence the development of healthy infant sleep patterns. Thus, these aspects are interwoven with each other and should be addressed together in communication with parents.

Conclusions

Health practitioners with different professional backgrounds need to search for an agreement on when and how different aspects of sleep-related knowledge should be communicated to new and expectant parents to enable the design of national follow-up programs. Parents want coherent and personalized services regarding infant sleep issues that may allow them to choose sleeping arrangements, routines, and behaviors that fit in with their sociocultural attitudes and traditions. Many different sources and formats may be used to empower parents regarding infant sleep issues. Studies have described the use of group or individual meetings, videos, and written materials. The key issue is the importance of consistent and seamless knowledge-based services.

Crying in the first 12 months of life: A systematic review and meta-analysis of cross-country parent-reported data and modeling of the "cry curve"

Crying is an ubiquitous communicative signal in infancy. This meta-analysis synthesizes data on parent-reported infant cry durations from 17 countries and 57 studies until infant age 12 months (N = 7580, 54% female from k = 44; majority White samples, where reported, k = 18), from studies before the end Sept. 2020. Most studies were conducted in the United States, the United Kingdom, and Canada (k = 32), and at the traditional cry "peak" (age 5-6 weeks), where the pooled estimate for cry and fuss duration was 126 mins (SD = 61), with high heterogeneity. Formal modeling of the meta-analytic data suggests that the duration of crying remains substantial in the first year of life, after an initial decline.

The effect of swaddling on infant sleep and arousal: A systematic review and narrative synthesis

BACKGROUND

Western parents swaddle infants to promote sleep and reduce night-waking, however recent evidence of the effects of swaddling on the sleep of healthy infants has not been systematically reviewed.

OBJECTIVE

To investigate the effect of swaddling on the sleep of infants up to 1 year of age using a narrative synthesis approach.

DATA SOURCES

We systematically searched five academic databases, including the Cochrane trial registry (Pubmed, PsycINFO, Embase, the Cochrane library, and Blackwell Synergy). We manually searched reference lists and citations of included studies and reference lists of existing reviews.

STUDY SELECTION

Studies of any type, published since 2007, reporting primary data whose subjects were humans up to 12 months of age with outcome measures relating to the impact of swaddling on sleep and arousal.

DATA EXTRACTION

By hand using a customized template. A narrative synthesis is used to present the results.

RESULTS

In total 171 studies were retrieved with 115 studies discarded at title. A further 43 were discarded at abstract, and six were discarded at full text. Two papers were combined as they reported on the same study giving a total of 6 studies that met the inclusion criteria for the review. An evidence hierarchy was used to assess Risk of Bias in the included studies; the results are presented via a narrative synthesis. Swaddling was associated with increased duration of quiet sleep in infants and a significantly reduced number of sleep state changes among infants naïve to the intervention.

LIMITATIONS

The integrity of the intervention (swaddling) including its baseline characteristics, was defined broadly across the included studies limiting the interpretation and transferability of the results of this review.

CONCLUSIONS

Swaddling appears to increase quiet sleep duration in infants and reduces the number of sleep state changes among infants naïve to the intervention. Parents should be made aware that implementing conditions unfavorable to arousability may increase SUDI risk among infant who have not previously been swaddled. This review has relevance for informing future practice recommendations and parent advice as well as in designing future studies.

Do sleep interventions change sleep duration in children aged 0-5 years? A systematic review and meta-analysis of randomised controlled trials

This review investigated whether randomised controlled trials attempting to improve sleep or prevent sleep problems in 0-5 year olds influenced nocturnal sleep duration, day-time naps, or 24-h sleep. Medline (Ovid), EMBASE, and CINAHL were searched from inception until 9 July 2020 and supplemented with hand searching. Search results were screened, eligible data were extracted, and risk of bias was assessed by at least two reviewers. Of 8571 publications considered, 32 trials which used a variety of subjective and objective sleep measurements were included in generic inverse variance random effects meta-analysis of nocturnal (n = 24), day-time (n = 14), and 24-h (n = 13) sleep duration. Overall, sleep interventions increased nocturnal sleep duration by a mean of 9 min (95% CI 4.1 to 13.8, I²28%) per night when compared with no sleep intervention. Increases were predominantly seen in sleep-only, rather than multi-component interventions. Total 24-h sleep duration tended to increase by a similar amount (8.6 min (95% CI -2.7 to 19.8, I² = 59%)), but this was mainly only seen in studies that assessed sleep using diaries. There was no evidence that interventions changed day-time sleep duration. Future studies should involve sleep-only rather than multi-component interventions, and use objective sleep measures (reviewregistry857).

The Effects of an Infant Calming Intervention on Mothers' Parenting Self-Efficacy and Satisfaction During the Postpartum Period: A Randomized Controlled Trial

The aim of this study was to evaluate the effects of a behavioral infant calming technique to support mothers' parenting self-efficacy and parenting satisfaction. The methods of this randomized controlled trial are based on the CONSORT guidelines. Data were collected during March 1 to May 20, 2019, from 3 postpartum units in 1 university-level hospital in Finland. A total of 250 mothers agreed to participate, of which 120 were randomly allocated to the intervention group and 130 to the control group. All mothers completed a baseline questionnaire before randomization. Mothers in the intervention group were taught the 5 S's infant calming technique. The control group received standard care. Follow-up data were collected 6 to 8 weeks postpartum. The primary outcome measure was the change in parenting self-efficacy and parenting satisfaction scores over the follow-up period. The intervention group showed significantly larger improvements in parenting self-efficacy scores. There were no statistically significant differences in median improvements in parenting satisfaction. The 5 S's infant calming technique is feasible. These study findings may assist midwifery and neonatal nursing staff to support mothers and families during the postpartum period, whether the infants are fussy or not.
