    Objective: Most infants become settled at night by 3 months of age, whereas infants not settled by 5 months are likely to have long-term sleep-waking problems. We assessed whether normal infant development in the first 3 months involves increasing sleep-period length or the ability to resettle autonomously after waking in the night. Methods: One hundred one infants were assessed at 5 weeks and 3 months of age using nighttime infrared video recordings and parental questionnaires. Results: The clearest development was in sleep length; 45% of infants slept continuously for 5 hours or more at night at 3 months compared with 10% at 5 weeks. In addition, around a quarter of infants woke and resettled themselves back to sleep in the night at each age. Autonomous resettling at 5 weeks predicted prolonged sleeping at 3 months suggesting it may be a developmental precursor. Infants reported by parents to sleep for a period of 5 hours or more included infants who resettled themselves and those with long sleeps. Three-month olds fed solely breast milk were as likely to self-resettle or have long sleep bouts as infants fed formula or mixed breast and formula milk. Conclusions: Infants are capable of resettling themselves back to sleep in the first 3 months of age; both autonomous resettling and prolonged sleeping are involved in “sleeping through the night” at an early age. Findings indicate the need for physiological studies of how arousal, waking, and resettling develop into sustained sleeping and of how environmental factors support these endogenous and behavioral processes

    The influence of infant irritability on maternal sensitivity in a sample of very premature infants

    The relationship between maternal sensitivity and infant irritability was investigated in a short-term longitudinal study of 29 very preterm infants. Infant irritability was assessed at term with the Brazelton NBAS, the Mother and Baby Scales (MABS) and the Crying Pattern Questionnaire (CPQ). Maternal sensitivity was assessed by nurses' ratings in the neonatal care unit and at three months during motherinfant interaction observation. Cross-lagged panel analysis indicated that neonatal irritability did not influence sensitivity at 3 months nor did maternal sensitivity in the newborn period lead to reduced irritability at 3 months. Both irritability and maternal sensitivity showed moderate stability over time (r=.55 and r=.60, respectively). It is concluded that in early infancy maternal sensitivity shows little influence on infant irritability in very preterm infants

    Descriptive figures for differences in parenting and infant night-time distress in the first three months of age

    Get PDF
    AIM: To provide descriptive figures for infant distress and associated parenting at night in normal London home environments during the first three months of age. BACKGROUND: Most western infants develop long night-time sleep periods by 4 months of age. However, 30% of infants in many countries sleep for short periods and cry out on waking in the night: the most common type of infant sleep behaviour problem. Preventive interventions may help families and improve services. There is evidence that 'limit-setting' parenting, which is common in western cultures, supports the development of settled infant night-time behaviour. However, a recent review has challenged this and argued that this form of parenting risks distressing infants. This study describes limit-setting parenting as practiced in London, compares it with ‘infant-cued’ parenting, and measures the associated infant distress. METHODS: Longitudinal infra-red video, diary and questionnaire observations comparing a General-Community (n=101) group and subgroups with a Bed-Sharing (n=19) group on measures of infant and parenting behaviours at night. FINDINGS: General-Community parents took longer to detect and respond to infant waking and signalling, and to begin feeding, compared with the highly infant-cued care provided by Bed-Sharing parents. The average latency in General-Community parents' responding to infant night-time waking was 3.5 minutes, during which infants fuss/cried for around one minute. Compared with Bed-Sharing parenting, General-Community parenting was associated with increased infant distress of around 30 minutes per night at 2 weeks, reducing to 12 minutes per night by three months of age. However, differences in infant distress between General-Community subgroups adopting limit-setting versus infant-cued parenting were not large or statistically significant at any age. The figures provide descriptive evidence about limit-setting parenting which may counter some doubts about this form of parenting and help parents and professionals to make choices

    Video evidence that parenting methods predict which infants develop long night-time sleep periods by three months of age

    Aim To examine two hypotheses about the longitudinal relationship between night-time parenting behaviours in the first few postnatal weeks and infant night-time sleep-waking at five weeks, three months and six months of age in normal London home environments. BACKGROUND: Most western infants develop long night-time sleep periods by four months of age. However, around 20-30% of infants in many countries continue to sleep for short periods and cry out on waking in the night: the most common type of infant sleep behaviour problem. Preventive interventions may help families and improve services. There is evidence that 'limit-setting' parenting, which is common in western cultures, supports the development of settled infant night-time behaviour. However, this evidence has been challenged. The present study measures three components of limit-setting parenting (response delay, feeding interval, settling method), examines their stability, and assesses the predictive relationship between each of them and infant sleep-waking behaviours. METHODS: Longitudinal observations comparing a General-Community (n=101) group and subgroups with a Bed-Sharing (n=19) group on infra-red video, diary and questionnaire measures of parenting behaviours and infant feeding and sleep-waking at night. Findings Bed-Sharing parenting was highly infant-cued and stable. General-Community parenting involved more limit-setting, but was less stable, than Bed-Sharing parenting. One element of General-Community parenting - consistently introducing a short interval before feeding - was associated with the development of longer infant night-time feed intervals and longer day-time feeds at five weeks, compared with other General-Community and Bed-Sharing infants. Twice as many General-Community infants whose parents introduced these short intervals before feeding in the early weeks slept for long night-time periods at three months of age on both video and parent-report measures, compared with other General-Community and Bed-Sharing infants. The findings' implications for our understanding of infant sleep-waking development, parenting programmes, and for practice and research, are discussed

    Excessive crying: behavioral and emotional regulation disorder in infancy

    Get PDF
    In the pediatric literature, excessive crying has been reported solely in association with 3-month colic and is described, if at all, as unexplained crying and fussing during the first 3 months of life. The bouts of crying are generally thought to be triggered by abdominal colic (over-inflation of the still immature gastrointestinal tract), and treatment is prescribed accordingly. According to this line of reasoning, excessive crying is harmless and resolves by the end of the third month without long-term consequences. However, there is evidence that it may cause tremendous distress in the mother-infant relationship, and can lead to disorders of behavioral and emotional regulation at the toddler stage (such as sleep and feeding disorders, chronic fussiness, excessive clinginess, and temper tantrums). Early treatment of excessive crying focuses on parent-infant communication, and parent-infant interaction in the context of soothing and settling the infant to sleep is a promising approach that may prevent later behavioral and emotional disorders in infancy

    Infant feeding bottle design, growth and behaviour: results from a randomised trial

    BACKGROUND: Whether the design of an anti-vacuum infant feeding bottle influences infant milk intake, growth or behavior is unknown, and was the subject of this randomized trial. METHODS: SUBJECTS: 63 (36 male) healthy, exclusively formula-fed term infants. INTERVENTION: Randomisation to use Bottle A (n = 31), one-way air valve: Philips Avent) versus Bottle B (n = 32), internal venting system: Dr Browns). 74 breast-fed reference infants were recruited, with randomisation (n = 24) to bottle A (n = 11) or B (n = 13) if bottle-feeding was subsequently introduced. Randomisation: stratified by gender and parity; computer-based telephone randomisation by independent clinical trials unit. SETTING: Infant home. PRIMARY OUTCOME MEASURE: infant weight gain to 4 weeks. SECONDARY OUTCOMES: (i) milk intake (ii) infant behaviour measured at 2 weeks (validated 3-day diary); (iii) risk of infection; (iv) continuation of breastfeeding following introduction of mixed feeding. RESULTS: Number analysed for primary outcome: Bottle A n = 29, Bottle B n = 25. PRIMARY OUTCOME: There was no significant difference in weight gain between randomised groups (0-4 weeks Bottle A 0.74 (SD 1.2) SDS versus bottle B 0.51 (0.39), mean difference 0.23 (95% CI -0.31 to 0.77). SECONDARY OUTCOMES: Infants using bottle A had significantly less reported fussing (mean 46 versus 74 minutes/day, p < 0.05) than those using bottle B. There was no significant difference in any other outcome measure. Breast-fed reference group: There were no significant differences in primary or secondary outcomes between breast-fed and formula fed infants. The likelyhood of breastfeeding at 3 months was not significantly different in infants subsequently randomised to bottle A or B. CONCLUSION: Bottle design may have short-term effects on infant behaviour which merit further investigation. No significant effects were seen on milk intake or growth; confidence in these findings is limited by the small sample size and this needs confirmation in a larger study.
