Abstract
The goal of this study was to compare how infants’ non-nutritive suck (NNS) changes throughout a suck sample. Fifty-four full-term infants (57% male) completed this study at, on average, 3.03 (SD .31) months of age. These infants sucked on our custom research pacifier for approximately five minutes. Infants produced, on average, 14.50 suck bursts during the sample. NNS data was pooled across subjects and breakpoint analyses were completed to determine if there were changes in their NNS patterning. Breakpoints were evident for NNS cycles per burst at burst numbers 18 and 34, and for amplitude (cmH20) at burst numbers 18 and 29. No breakpoints were present for NNS frequency. Infants exhibit changes in their suck physiology across burst number. When assessing suck, developmental specialists should observe more than one suck burst to attain a more valid and appropriate scope of the infant’s suck ability.

Abstract
Introduction: The assessment of dysphagia in preterm infants has been limited to clinical bedside evaluation followed by videofluoroscopic swallow study (VFSS) in selected patients. Recently, fiberoptic endoscopic evaluation of swallowing (FEES) is being described more in literature for preterm infants. However, it is unclear if one test has a better diagnostic utility than the other in this population. Furthermore, it is also unclear if performing FEES and VFSS simultaneously will increase the sensitivity and specificity of detecting dysphagia compared to either test performed independently. Objectives: The primary objective of this study is to evaluate the feasibility of performing VFSS and FEES simultaneously in preterm infants. Our secondary objective is to determine whether simultaneously performed VFSS-FEES improves the diagnostic ability in detecting dysphagia in preterm infants compared to either test done separately. Methods: In this pilot study, we describe the process involved in performing simultaneous VFSS-FEES in five preterm infants (postmenstrual age ≥36 weeks) with dysphagia. A total of 26 linked VFSS-FEES swallows were analyzed, where the same bolus during the same swallow was compared using simultaneous fluoroscopy and endoscopy. The sensitivity and specificity of detecting penetration and aspiration were evaluated in simultaneous VFSS-FEES compared with each test done independently. Results: Our results demonstrated that performing simultaneous VFSS-FEES is feasible in preterm infants with dysphagia. All patients tolerated the procedures well without any complications. Our pilot study in these five symptomatic preterm infants demonstrated a low incidence of aspiration but a high incidence of penetration. Simultaneous VFSS-FEES (26 linked swallows) improved the ability to detect penetration compared to each test done separately. Conclusion: To our knowledge, this study is the first to demonstrate the feasibility of performing VFSS and FEES simultaneously in symptomatic preterm infants with dysphagia resulting in potentially higher diagnostic yield than either procedure done separately.

Raczyńska A, Gulczyńska E. The impact of positioning on bottle-feeding in preterm infants (≤ 34 GA). A comparative study of the semi-elevated and the side-lying position - a pilot study. DEVELOPMENTAL PERIOD MEDICINE 2019.

Abstract
OBJECTIVE Objective: The aim of the study was to compare the advantages of semi-elevated and side-lying positioning during bottle-feeding of preterm infants ≤ 34 weeks gestational age (34+0/7). PATIENTS AND METHODS Material and methods: The study included six neonates (n=6) born ≤ 34 weeks gestational age who reached the age ≥ 32 weeks of postmenstrual age on the day when the study began and were hospitalized in the neonatology ward. Four bottle-feeding sessions were tested in each of the newborns: two in the side-lying and two in the semi-elevated position. The position for the first test was chosen randomly. For each of the positions twelve feeding sessions were examined and each preterm infant had bottle-feeding sessions analyzed both in the semi-elevated and side-lying positions. The level of saturation and heart rate were measured as the parameters indicative of the newborn's physiological stability. The factors determining the qualitative aspect of feeding included the level of the newborn's alertness and the occurrence of choking episodes. The amount of food consumed and the duration of the feeding were also recorded. RESULTS Results: The side-lying position was more effective with regard to the total amount of sustenance consumed as compared to the semi-elevated feeding position and the study result was statistically significant (p=0.007). The difference in the number of chokes between the study groups was not statistically significant, although a trend towards a reduced number of choking episodes was observed among infants fed in the side-lying position (p=0.090). There were no significant differences in oxygen saturation, heart rate and level of activity between the study groups. CONCLUSION Conclusions: The effects of this pilot study demonstrate the efficacy of the side-lying feeding position regarding the final amount of milk intake. The side-lying position may also reduce the number of choking episodes during the feeding. The results suggest the need to extend the study in order to confirm the potential benefits of using the side-lying position.

Abstract
OBJECTIVES Describe symptoms of feeding problems in children born very preterm (<32 weeks gestation) and moderate to late preterm (32-37 weeks gestation) compared to children born full-term; explore the contribution of medical risk factors to problematic feeding symptoms. METHODS The sample included 57 very preterm, 199 moderate to late preterm, and 979 full-term born children ages 6 months to 7 years. Symptoms of feeding problems were assessed using the Pediatric Eating Assessment Tool and compared between groups after accounting for the child's age and/or sex. With the sample of preterm children, we further analyzed 11 medical factors as potential risk factors affecting a child's feeding symptoms: feeding problems in early infancy and conditions of oxygen requirement past 40 weeks of postmenstrual age, congenital heart disease, structural anomaly, genetic disorder, cerebral palsy, developmental delay, speech-language delay, sensory processing disorder, vision impairment, or symptoms of gastroesophageal reflux. RESULTS Compared to children born full-term, both very preterm and moderate to late preterm born children had significantly higher scores on the Pediatric Eating Assessment Tool total scale and all 4 subscales. More severe symptoms were noted in very preterm children, particularly in the areas of Physiologic Symptoms and Selective/Restrictive Eating. Among preterm children, all 11 medical factors were found to be associated significantly with increased symptoms of feeding problems. CONCLUSION Compared to children born full-term, preterm born children demonstrated greater symptoms of feeding problems regardless of their current age, suggesting children born preterm may require more careful monitoring of feeding throughout childhood.

Abstract
BACKGROUND Achievement of independent oral feeding is a major determinant of discharge and contributes to long lengths of stay. Accumulating evidence suggests that there is great variation between and within newborn intensive care units in the initiation and advancement of oral feeding. The Infant-Driven Feeding (IDF) method is composed of 3 behavioral assessments including feeding readiness, quality of feeding, and caregiver support. Each assessment includes 5 categories and is intended as a method of communication among caregivers regarding the infant's readiness and progression toward independent oral feeding. PURPOSE To identify and summarize the available evidence on the use of the IDF method at initiation of oral feeds, time to independent oral feedings, and length of stay in the newborn intensive care unit or level II nursery for preterm infants. METHODS/SEARCH STRATEGY Four databases including CINAHL, Medline/PubMed, Ovid Nursing, and Embase were searched for "infant guided feedings," "infant driven feeding," "cue-based feeding," and "co regulated feeding." The full text of 32 articles was reviewed to identify experimental, quasiexperimental, or retrospective design to assess the evidence related to cue-based feeding. FINDINGS There were no randomized control, quasi-experimental, or retrospective studies utilizing the IDF method. There were 3 quality improvement projects utilizing the IDF method. The findings were conflicting: 1 project found the IDF method favorable in the achievement of full oral feedings, 2 projects found the IDF method favorable for reducing length of stay, and 1 project did not find differences in initiation, achievement of oral feedings, or length of stay. IMPLICATIONS FOR PRACTICE There is scant evidence limited to quality improvement projects to support the use of the IDF method. IMPLICATIONS FOR RESEARCH Research is needed to empirically validate the IDF method and to inform practice related to the initiation and advancement of oral feeding for preterm infants.

Abstract
Background and Objective: Strategies to transition preterm infants from tube to oral feeding vary greatly and the transition may take days to weeks. The study objective was to evaluate the effect of parental guided responsive feeding (PGRF) on this transition. Methods: We conducted a randomized controlled trial on infants born at <32 weeks gestation. The PGRF intervention was performed by parents, and included feeding intervals and volumes which were guided by the infants' behavioral cues of hunger and satiety. If a minimum volume was not taken orally, an intermediate volume was supplemented via nasogastric tube. The control group was traditionally fed (TF), with pre-planned volumes of intake and at given scheduled intervals. Results: The study comprised 67 infants (PGRF 32, TF 35). PGRF infants reached full oral feeding within less days (median 2 vs. 8 days, p = 0.001), at an earlier age (median 34.28 vs. 35.14 weeks, p < 0.001), returned to baseline weight gain at 35 weeks (1.77 ± 0.70 vs. 1.25 ± 0.63 g/kg/day, p = 0.002), were discharged earlier (36.34 ± 0.6 vs. 36.86 ± 0.9 weeks, p = 0.001), were more likely to be fed by their parents (p < 0.001), and experienced less apnea/bradycardia events at 34 weeks (median 3.5 vs. 9 per week p = 0.047) compared to the TF infants. The regression model demonstrated that independent variables predicted 43.7% of the variance of time to full oral feeding [F (9, 65) = 4.84 p < 0.001]. The only significant variable was feeding group (B = -6.43 p < 0.001); The PGRF infants were more likely to reach full oral feeding earlier. Conclusion: PGRF is safe, and associated with short-term advantages, higher parental engagement, and earlier discharge.

Abstract
BACKGROUND Supporting infants as they develop feeding skills is an essential component of neonatal and pediatric care. Selecting appropriate and supportive interventions begins with a thorough assessment of the infant's skills. The Early Feeding Skills (EFS) tool is a clinician-reported instrument developed to assess the emergence of early feeding skills and identify domains in need of intervention. PURPOSE The purpose of this study was to identify the factor structure of the EFS and test its psychometric properties, including internal consistency reliability and construct validity. METHODS EFS-trained interprofessional clinicians in 3 settings scored 142 feeding observations of infants 33 to 50 weeks' postmenstrual age. Redundant and rarely endorsed items were removed. Factor analysis methods clustered items into subscales. Construct validity was examined through the association of the EFS with (1) concurrently scored Infant-Driven Feeding Scale-Quality (IDFS-Q), (2) infant birth risk (gestational age), and (3) maturity (postmenstrual age). RESULTS Principal components analysis with varimax rotation supported a 5-factor structure. The total EFS demonstrated good internal consistency reliability (Cronbach α= 0.81). The total EFS score had construct validity with the IDFS-Q (r =-0.73; P < .01), and with gestational age of a subsample of premature infants (r = 0.22; P < .05). IMPLICATIONS FOR PRACTICE As a valid and reliable tool, the EFS can assist the interprofessional feeding team to organize feeding assessment and plan care. IMPLICATIONS FOR RESEARCH The strong psychometric properties of the EFS support its use in future research.

Abstract
PURPOSE To describe the clinical properties and psychometric soundness of infant oral motor feeding assessments available for practice. METHODS A systematic review was conducted using six databases (PubMed, Ovid [Medline], CINHAL, EMBASE, psycINFO, and COCHRANE) to retrieve articles. Assessments were analyzed for their clinical characteristics and psychometric robustness. RESULTS Ten assessment tools were identified to meet the inclusion/exclusion criteria. Clinical properties of the tools varied from assessments which assessed oral feeding readiness, oral motor function, and pre-feeding skills for breast and/or bottle feeding. Psychometric evidence was found for seven assessment tools. The Neonatal Oral Motor Assessment Scale was found to be the most widely tested for psychometric soundness. The overall psychometric evidence was inconsistent and/or inadequate for the evaluative tools. CONCLUSIONS Findings from this systematic review demonstrate clinical usefulness of the tools based on their assessment properties, however additional studies are needed to further establish their psychometric soundness.

Abstract
BACKGROUND Side-lying position is an increasingly common feeding strategy used by parents, nurses, and feeding therapists to support oral feeding in preterm infants. Better understanding of the research evidence on the effect of the side-lying position will help clinicians make informed decisions and guide future research in this important area. PURPOSE To identify and summarize the available evidence on the effect of side-lying position on oral feeding outcomes in preterm infants. METHODS/SEARCH STRATEGY PubMed, CINAHL, Web of Science and PsycINFO were searched for ("preterm" OR "premature") AND "feed*" AND "position*". The full text of 47 articles was reviewed to identify eligible studies that use a quasi-experimental or experimental design to examine the intervention effectiveness; 4 studies met criteria. FINDINGS/RESULTS Four studies compared the effect of the side-lying position with either the semi-upright, cradle-hold, or semi-reclined positions on various feeding outcomes. The findings were conflicting: 2 studies found the side-lying position to be beneficial for supporting physiologic stability during feeding compared with the semi-upright position whereas 2 studies did not find significant differences in any of their outcomes between the side-lying position and other feeding positions. However, this finding should be interpreted cautiously because of various methodological weaknesses and limited generalizability. IMPLICATIONS FOR PRACTICE This review does not provide strong or consistent evidence that the side-lying position improves preterm infants' oral feeding outcomes. IMPLICATIONS FOR RESEARCH A large randomized controlled trial with a diverse group of preterm infants is needed to determine the effects of the side-lying position and identify infants who would receive the most benefit.Video Abstract Available at https://journals.lww.com/advancesinneonatalcare/Pages/videogallery.aspx.

Abstract
The hypothalamic nonapeptides oxytocin and vasopressin are important modulators of socio-affective behaviours in a wide variety of animal species, including humans. Nevertheless, there is little research addressing their possible roles on socio-affective dimensions of human behaviour across development, during which considerable behavioural and physiological change occurs. Questions still remain about the extent to which findings from adults may directly apply to earlier phases of human development. In this article, we systematically summarize and discuss all existing studies investigating the developmental association of endogenous levels of hypothalamic neuropeptides oxytocin and vasopressin with human social behaviour or on its disruption in paediatric populations. Evidence is sparse insofar as there are still relatively few developmental studies and limited due to correlational research designs and unreliability of methods currently used for neuropeptide measurements in biological fluids. The findings to date generally converge with adult evidence, but also suggest that important differences between age stages may exist. Further studies focusing these differences may prove critical for informing drug development for socio-affective deficits in paediatric populations.

Abstract
PURPOSE The aim of this randomized controlled study was to determine the effect of semielevated side-lying (ESL) and semielevated supine (ESU) positions, which are used to bottle-feed preterm infants, on their physiological characteristics and feeding performance. DESIGN AND METHODS The sample consisted of preterm infants who were born in the 31st gestational week and below, and met the inclusion criteria. A randomization was provided in the sample group with a total of 80 infants including 38 infants in the ESL (experimental) group and 42 infants in the ESU (control) group. Both groups were compared in terms of their SpO2 values, heart rates, and feeding performances before, during, and after the feeding. The data were obtained by using a form for infant descriptive characteristics, feeding follow-up form, a Masimo Radical-7 pulse oximeter device, and a video camera. RESULTS It was determined that the infants in the ESL group had statistically significantly higher SpO2 values (ESL: 96.77 ± 2.51; ESU: 93.48 ± 5.63) and lower heart rates (ESL: 155.87 ± 11.18; ESU: 164.35 ± 6.00) during the feeding compared to the infants in the ESU group (p < .05). Besides, oxygen saturation levels of the infants in the ESU group decreased more (p < .01) and their heart rates increased more (p < .05) during the feeding than those obtained before the feeding compared to the infants in the ESL group. PRACTICE IMPLICATIONS The ESL position has a more positive effect on oxygen saturation and heart rate of infants and it is more effective in providing a physiological stabilization during the feeding, compared to the ESU position. According to these results, the ESL position can be recommended for preterm feeding.

Abstract
Extremely premature infants, born 28 weeks gestation or less, are at high risk for impaired socioemotional development, due in part to exposure to early stressful social experiences that alter brain development. Understanding mediators that link experience with outcomes is necessary to assess premature infant responses to social experiences that are critical to brain development. The hormone oxytocin (OT), released during supportive interactions, has potential as a biomarker of the premature infant's responses to social experiences. The purpose of this study was to examine associations among infant plasma OT trajectories and maternal-infant social engagement behaviors during initial hospitalization. This study also examined demographic correlates of engagement behaviors in mothers and infants. Plasma from 28 extremely premature infants, born gestational ages 25-28 6/7 weeks, was collected at 14 days of life, then weekly until 34 weeks. Social engagement behaviors were measured by the Parent-Child Early Relational Assessment during a videotaped feeding when the infant was receiving one-quarter full oral feeds. Maternal-infant demographics were extracted from the medical record. Higher infant plasma OT was associated with lower infant social engagement, but no associations were found with maternal social engagement. Infant social engagement was positively related to maternal social engagement. Maternal parity was related to maternal social engagement, and infant demographics did not predict infant social engagement. The significant, yet negative, association between infant OT and engagement provides support for the measurement of OT as a neurobiological antecedent to infant social behaviors. Finally, this research suggests that during the earliest period of infant socio-behavioral development, premature infants are behaviorally reactive to the social engagement behaviors of their mothers.

Abstract
Little is known about the relationship between maternal behavior and the stability of premature infants' physiologic responses during feeding. In a secondary data analysis, we examined relationships between quality of maternal behavior and cardiorespiratory physiology during feeding in 61 premature and 53 term infants at four times over the first year of life. Measures included heart rate (HR), respiratory rate (RR), and oxygen saturation; Child Feeding Skills Checklist; and Parent-Child Early Relational Assessment. Birthweight, gestational age, and neurodevelopmental risk were covariates. Quality of maternal behavior did not predict infants' physiologic response to feeding. However, birthweight was related to infant feeding physiology among all infants over the first year of life. Stress during fetal life, which may lead to impaired intrauterine growth and low birthweight, may have longitudinal effects on cardiorespiratory functioning of premature infants. Research is needed to further investigate the biological pathways by which maternal-infant interaction supports behavioral and physiologic feeding outcomes of premature infants.

Abstract
Oral feeding readiness has been described by researchers in the neonatal intensive care unit, and research has continued on this topic for many years. The purpose of this narrative review is to identify research and practice guidelines related to oral feeding readiness in preterm infants that have occurred during the last decade. The introduction and mastery of oral feeding is a major developmental task for the preterm infant that is often a prerequisite for discharge from the neonatal intensive care unit. Having a better understanding of the evidence supporting the development of this skill will help the practicing nurse choose appropriate interventions and the researcher to develop trajectories of research that continue to increase our knowledge in this important practice area.

Abstract
Very preterm (VP, ≤30 wk gestational age) infants are at risk for impaired lung function, which significantly limits their ability to eat. A semielevated side-lying (ESL) position is a feeding strategy that may improve oral feeding by supporting breathing during feeding. The study evaluated the efficacy of the ESL position compared with the semielevated supine (ESU) position on physiological stability and feeding performance of bottle-fed VP infants. Using a within-subject crossover design, 6 VP infants were bottle-fed twice on 1 day, in both the ESL and ESU positions in a random order. Physiological stability (heart rate, oxygen saturation [SaO2], and respiratory characteristics) and feeding performance (percent intake, proficiency, efficiency, and duration of feeding) were measured before and/or during feeding. Very preterm infants fed in the ESL position demonstrated significantly less variation in heart rate, less severe and fewer decreases in heart rate, respiratory rate that was closer to the prefeeding state, shorter and more regular intervals between breaths, and briefer feeding-related apneic events. No significant differences for SaO2 or feeding performance were found. The findings indicate that the ESL position may support better regulation of breathing during feeding, thereby allowing VP infants to better maintain physiological stability throughout feeding.

Abstract
The purpose of this article is to introduce a model of neurodevelopmental risk and protection that may explain some of the relationships among biobehavioral risks, environmental risks, and caregiving behaviors that potentially contribute to neurobehavioral and cognitive outcomes. Infants born before 30 weeks of gestation have the poorest developmental prognosis of all infants. These infants have lengthy hospitalization periods in the neonatal intensive care unit (NICU,) an environment that is not always supportive of brain development and long-term developmental needs. The model supports the premise that interventions focused on neuroprotection during the neonatal period have the potential to positively affect long-term developmental outcomes for vulnerable very preterm infants. Finding ways to better understand the complex relationships among NICU-based interventions and long-term outcomes are important to guiding caregiving practices in the NICU.

Abstract
BACKGROUND The transition from gavage to nipple feeding is difficult for preterm infants with bronchopulmonary dysplasia because of tachypnea and hypoxemia from chronic respiratory distress. OBJECTIVE The aim of this study was to test the hypothesis that preterm infants with bronchopulmonary dysplasia who transitioned from gavage to nipple feeding with the semidemand method would achieve nipple feeding sooner and be discharged from hospital sooner than control infants who received standard care. METHODS Forty-two infants were randomized to the control condition and 44 to the experimental protocol. Mean gestational ages and birth weights were 25 ± 1.5 weeks and 784 g for controls and 25 ± 1.4 weeks and 787 g for experimental infants. Control infants received standard care that included gradual increases in the number of nipple to gavage feedings per day. Experimental infants received the semidemand method that used infant behavioral and cardiorespiratory signs to regulate frequency, length, and volume of nipple feedings. General linear model procedures were used to compare study groups. RESULTS Experimental infants achieved nipple feeding at M = 5.9 ± 0.7 days compared with control infants, M = 12.3 ± 0.8 (p < .0001). Length of hospitalization was not significantly different between groups. DISCUSSION The semidemand method significantly shortened the time for infants to attain nipple feeding in a manner taking their respiratory distress into consideration.

Abstract
PURPOSE The purpose of this study was to test a coding system, the Maternal-Infant Synchrony Scale (MISS), for assessing synchrony of feeding interaction between a mother and her preterm infant. The secondary aim was to describe mother and preterm infant synchrony during feeding and the change over time. METHODS A descriptive, longitudinal design using data collected during an earlier study was employed, using a sample dataset from 10 mother-infant dyads that completed three data collection points. The Noldus Observer XT 8.0 (Noldus Information Technology b.v., 2006) was used for data review and coding. The MISS was created from pilot data and definitions further refined. The frequency of occurrence for select behaviors and the percentage of time behaviors occurred during the feeding and the changes in behaviors over the three observations periods were calculated. RESULTS The synchrony tool developed in this study demonstrates that changes occur in mother and infant behavior over time. Mothers were attentive and focused during feedings and monitored their infants' sucking intently but there was little interaction between the dyad. Infant attempts at interaction were greater than the mother attempts to engage her infant. The influence of infant maturation on feeding behaviors was evident across observations. CONCLUSION This study revealed behaviors that are descriptive of the interaction and can be used to develop interventions that would support the developing relationship. Use of the MISS with a larger sample size and a cohort of healthy, term newborns is needed to establish the MISS as a valid and reliable measure of synchrony.

Abstract
Premature infants confront numerous physiologic and environmental stressors in the neonatal intensive care unit (NICU) that have the potential to permanently alter their neurodevelopment. Schore's regulation theory postulates that positive maternal-infant interactions can shape the infant's developmental outcomes through inducing mechanistic changes in brain structure and function. The purposes of this article are to explain the regulation of infant neurobiological processes during interactions between mothers and healthy infants in the context of Schore's theory, to identify threats to these processes for premature infants, and to propose principles of clinical practice and areas of research necessary to establish a supportive environment and prevent or reduce maladaptive consequences for these vulnerable infants. A premature birth results in the disruption of neurodevelopment at a critical time. Chronic exposure to stressors related to the NICU environment overwhelms immature physiologic and stress systems, resulting in significant allostatic load, as measured by long-term neurodevelopmental impairments in the premature infant. Positive maternal-infant interactions during NICU hospitalization and beyond have the potential to reduce neurologic deficits and maximize positive neurodevelopmental outcomes in premature infants. The quality of the maternal-infant interaction is affected not only by the infant's developing neurobiology but also by the mother's responses to the stressors surrounding a premature birth and mothering an infant in the NICU environment. Nurses can empower mothers to overcome these stressors, promote sensitive interactions with their infants, and facilitate neurodevelopment. Research is critically needed to develop and test nursing interventions directed at assisting mothers in supporting optimal neurodevelopment for their infants.

Abstract
The Support of Oral Feeding for Fragile Infants (SOFFI) method of bottle-feeding rests on quality evidence along with implementation details drawn from clinical experience. To be clear, the SOFFI Method is not focused on the amount of food taken in but on the conduct of the feeding and the development of competent infant feeding behavior that, consequently, assures the intake of food necessary for growth. The unique contribution of the SOFFI method is the systematic organization of scientific findings into clinically valid and reliable, easily followed algorithms, and a manualized Reference Guide for the assessments, decisions, and actions of a quality feeding.A quality feeding is recognized by a stable, self-regulated infant and a caregiver who sensitively (responsively) adjusts to the infant's physiology and behavior to realize an individualized feeding experience in which the infant remains comfortable and competent using his nascent abilities to ingest a comfortable amount of milk/formula. The SOFFI Reference Guide and Algorithms begin with prefeeding adjustments of the environment and follow step by step through a feeding with observations of specific infant behavior, decisions based on that behavior, and specific actions to safeguard emerging abilities and the quality of the experience. An important aspect the SOFFI Reference Guide and Algorithms is the clarity about pausing and stopping the feeding on the basis of the infant's physiology and behavior rather than on the basis of the amount ingested. The specificity of each observation, decision, and action enables nurses at all levels of experience to provide quality, highly individualized, holistic feedings. Throughout the course of feeding in the NICU, the nurse conveys to parents the integrated details (observations, decisions, and actions) particular to their infant, thus passing on the means for parents to become competent in quality feeding, to enjoy feeding time into the future, and to gain in confidence as they watch their infants grow.

Abstract
Successful oral feeding of preterm and other ill and fragile infants is an interactive process that requires (1) sensitive, ongoing assessment of an infant's physiology and behavior, (2) knowledgeable decisions that support immediate and long-term enjoyment of food, and (3) competent skill in feeding. Caregivers can support feeding success by using the infant's biological and behavioral channels of communication to inform their feeding decisions and actions. The Supporting Oral Feeding in Fragile Infants (SOFFI) Method is described here with text, algorithms, and reference guides. Two of the algorithms and the reference guides are published separately as Philbin, Ross. SOFFI Reference Guides: Text, Algorithms, and Appendices (in review). The information in all of these materials is drawn from sound research findings and, rarely, when such findings are not available, from expert, commonly accepted clinical practice. If the quality of a feeding takes priority over the quantity ingested, feeding skill develops pleasurably and at the infant's own pace. Once physiologic organization and behavioral skills are established, an affinity for feeding and the ingestion of sufficient quantity occur naturally, often rapidly, and at approximately the same postmenstrual age as volume-focused feedings. Nurses, therapists, and parents alike can use the SOFFI Method to increase the likelihood of feeding success in the population of infants at risk for feeding problems that emerge in infancy and extend into the preschool years.

Abstract
Preterm infants often display difficulty establishing oral feeding in the weeks following birth. This article aims to provide an overview of the literature investigating the development of feeding skills in preterm infants, as well as of interventions aimed at assisting preterm infants to develop their feeding skills. Available research suggests that preterm infants born at a lower gestational age and/or with a greater degree of morbidity are most at risk of early feeding difficulties. Respiratory disease was identified as a particular risk factor. Mechanisms for feeding difficulty identified in the literature include immature or dysfunctional sucking skills and poor suck–swallow–breath coordination. Available evidence provides some support for therapy interventions aimed at improving feeding skills, as well as the use of restricted milk flow to assist with maintaining appropriate ventilation during feeds. Further research is needed to confirm these findings, as well as to answer remaining clinical questions.

Abstract
BACKGROUND Compromised parasympathetic response to stressors may underlie feeding difficulties in infants with complex congenital heart defects, but little is known about the temporal pattern of parasympathetic response across phases of feeding. OBJECTIVES The aim of this study was to describe initial data exploration of trajectories of parasympathetic response to feeding in 15 infants with surgically corrected transposition of the great arteries and to explore the effects of feeding method, feeding skill, and maternal sensitivity on trajectories. METHOD In this descriptive, exploratory study, parasympathetic function was measured using high-frequency heart rate variability (HF HRV), feeding skill was measured using the Early Feeding Skills assessment, and maternal sensitivity was measured using the Parent-Child Early Relational Assessment. Data were collected before, during, and after feeding at 2 weeks and 2 months of age. Trajectories of parasympathetic function and relationships with possible contributing factors were examined graphically. RESULTS Marked between-infant variability in HF HRV across phases of feeding was apparent at both ages, although it was attenuated at 2 months. Four patterns of HF HRV trajectories across phases of feeding were identified and associated with feeding method, feeding skill, and maternal sensitivity. Developmental increases in HF HRV were apparent in most breast-fed, but not bottle-fed, infants. DISCUSSION This exploratory data analysis provides critical information in preparation for a larger study in which varying trajectories and potential contributing factors can be modeled in relationship to infant outcomes. Findings support inclusion of feeding method, feeding skill, and maternal sensitivity in modeling parasympathetic function across feeding.

Abstract
Current research on feeding outcomes after discharge from the neonatal intensive care unit (NICU) suggests a need to critically look at the early underpinnings of persistent feeding problems in extremely preterm infants. Concepts of dynamic systems theory and sensitive care-giving are used to describe the specialized needs of this fragile population related to the emergence of safe and successful feeding and swallowing. Focusing on the infant as a co-regulatory partner and embracing a framework of an infant-driven, versus volume-driven, feeding approach are highlighted as best supporting the preterm infant's developmental strivings and long-term well-being.

Abstract
Synchrony is an essential component of the interaction between a mother and her infant and is characterized by adaptive and reciprocal behaviors that promote a mutually rewarding interaction. It is an antecedent for the emergence of self-regulatory function in infants and influences current and future interactions. Understanding the dynamics of the mother-infant dyad and identifying synchronous patterns are important for promoting a healthy relationship. Approaches to measurement and challenges to model development are described.

OBJECTIVE To describe the development and evaluation of an observation system to assess the process of mother-infant feeding interaction relevant to infant neuro-behavioral regulation: the Mother-Infant Feeding Tool. DESIGN Secondary analysis. SETTING Special care nursery just before discharge and in the home at 1 and 4 months postterm age. PARTICIPANTS Forty-three mother-infant dyads. METHODS Videotaped feeding interactions were examined to assess regulatory processes of mother-infant interaction. Data were collected at three times over the infant's first 4 postterm months: before the infant's discharge from the special care nursery and at 1 and 4 months postterm age in the home. RESULTS Across all three data points mothers rarely talked to their infants. CONCLUSION Further testing is needed, but the Mother-Infant Feeding Tool shows promise in assessing very early mother-infant feeding interactions.

Abstract
OBJECTIVE To compare physiological regulation and the effect of maternal sensitive caregiving during feeding on physiological regulation in healthy infants and in infants with transposition of the great arteries. DESIGN Descriptive, 2 groups, repeated measures. SETTING Three children's hospitals in the Midwest. PARTICIPANTS A convenience sample of 15 infants with transposition of the great arteries matched with 16 healthy infants. METHODS Measures of physiological regulation before, during, and after feeding and quality of maternal affect and behavior during feeding were collected postoperatively at 2 weeks and 2 months of age. RESULTS At 2 weeks, infants with transposition of the great arteries demonstrated impaired physiological regulation with feedings when compared with healthy infants. Healthy infants of more sensitive mothers were more likely to demonstrate a physiologically adaptive response during feeding. Maternal effect on physiological regulation was not observed in infants with transposition of the great arteries. No differences between groups were found at 2 months. CONCLUSIONS For infants with transposition of the great arteries, effects of surgical recovery and limited contact with their mothers relative to healthy infants may have outweighed the supportive effect of maternal sensitivity during feeding in the early weeks of life. Further research is needed to identify ways of enhancing the regulatory effect of maternal behavior on infants with heart defects.

Abstract
OBJECTIVE The purpose of this analysis was to investigate the effect of oral feeding experience on clinical outcomes (time to full oral feedings and length of stay) in preterm infants. STUDY DESIGN This analysis was completed on 92 infants who participated in a longitudinal, non-experimental study. Data were collected daily for maturity, weight and experience at oral feeding. Additional data were collected to assess overall morbidity. RESULT Time to full oral feedings was predicted by experience at oral feeding and morbidity. Length of stay from the start of oral feedings until discharge was predicted by feeding experience and by maturity at the first oral feeding. Weight gain was not affected by feeding experience. CONCLUSION Experience at feeding may result in more rapid transition to full oral feedings regardless of severity of illness and may contribute to shorter length of stay. These positive clinical outcomes related to feeding experience warrant further research attention.

Abstract
Feeding is a primary concern for families of extremely preterm (EP) infants following discharge from neonatal care. An increasing number of EP children are being referred for treatment of feeding problems, including eating only a few types of food or very small portions, difficulty transitioning to textured foods, and refusing food. These issues have the potential for significant consequences for the children's growth and development as well as their family's well-being. An understanding of the kinds of feeding problems faced by families of EP infants can help nurses guide families to be ready for and respond to these issues. In this article, the evidence for and the nature of feeding problems in EP children after discharge from neonatal care are examined.

Abstract
This study compared the effects of oral stimulation with those of oral support on non-nutritive sucking and feeding parameters in preterm infants. Preterm infants (23 males, 20 females) born between 29 and less than 34 weeks' gestational age (GA; mean GA 31.2wks [standard error of mean{SEM} 0.39]; mean birth-weight 1580g [SEM 120]) were allocated to one of three experimental groups: (Stimulation+support [five males, four females]; Stimulation [four males, seven females]; and Support [seven males, five females]) or a control group. Non-nutritive sucking pressure and sucking activity were quantified in the gavage and transition periods. Oral support minimizes fluid loss, stabilizes the jaw, and organizes deglutition. The time of transition, the quantity of milk ingested per day, and the number of bottle feeds per day were recorded. Variables were analyzed by repeated-measures analysis of variance, with birth-weight as covariate (ANCOVA). Transition time was reduced (p<0.0001) for the Stimulation+support and Support groups. ANCOVA computed during gavage showed increased non-nutritive sucking pressure and sucking activity (p<0.001) for the Stimulation and Stimulation+support groups. ANCOVA computed during transition revealed increases in non-nutritive sucking pressure and daily bottle feeds (p<0.001) for the three experimental groups and in daily milk ingested (p=0.002) for the Stimulation+support and Support groups. We demonstrated that oral support is the result of both the action of chin and cheek support, and the aid to deglutition. An analysis of the organization of sucking patterns should be undertaken to provide better understanding of the mechanisms involved in oral support.

Abstract
OBJECTIVE The purposes of this analysis were to determine how select characteristics of nutritive sucking (number of sucks, sucks/burst, and sucks/minute) change over time and to examine the effect of select factors (morbidity, maturity, prefeeding behavior state, and feeding experience) on those changes. STUDY DESIGN A longitudinal, non-experimental study was conducted in a Level 3 neonatal intensive care unit using a convenience sample of 88 preterm infants. Statistical analyses were performed using a repeated-measures mixed-model in SAS. RESULTS Sucking activity (number of sucks, sucks/burst, and sucks/minute) was predicted by morbidity, maturity, feeding experience and prefeeding behavior state. Experience at oral feeding had the greatest effect on changes in the number of sucks, suck/burst and sucks/minute. CONCLUSION Experience at feeding may result in more rapid maturation of sucking characteristics.

Abstract
Preterm infants develop the skills necessary to begin oral feeding as their health stabilizes and as they reach a postconceptional age that supports coordination of breathing and swallowing with oral-motor functioning. The time from initiation of oral feeding to full oral feedings (with adequate intake for growth and maintenance of physiologic stability) can vary from days to months for the preterm infant. The approach to feeding the infant during this transition period must be developmentally supportive and tailored to meet the needs of the individual. To accomplish this, caregivers--notably nurses and parents--need to communicate about the specific skills that the infant has gained, about skills that are emerging, and about skills that the infant has not yet developed. The Early Feeding Skills (EFS) Assessment is a checklist for assessing infant readiness for and tolerance of feeding and for profiling the infant's developmental stage regarding specific feeding skills: the abilities to remain engaged in feeding, organize oral-motor functioning, coordinate swallowing with breathing, and maintain physiologic stability. This article introduces the EFS.
