Sleep quality in early life has implications for individual and family well-being [19]. Parenting in the early months may be highly influential on infant sleep patterns and trajectories.
This study used observational and survey data to investigate how sleeping arrangement and two types of nighttime interventions at one and three months (non-distress-initiated and distress-initiated) are associated with infants' sleep development across the first nine months. Distress-initiated interventions were identified as parents' responses to infants' distress signals whereas non-distress initiated interventions were identified as parents' behaviors in response to non-distressed vocalizations or while infants were asleep.
Analysis from 107 families revealed that infant night wakings decreased over time as expected. The link between early non-distress initiated interventions and rate of change in infant night wakings was significantly moderated by sleep arrangement such that solitary sleeping infants who experienced higher levels of non-distress-initiated interventions showed a less steep decline across time in infant night wakings compared to solitary infants who experienced low levels of non-distress-initiated interventions. Results also showed that higher levels of distress-initiated interventions at one and three months were associated with a steeper decrease in infant night wakings for both solitary and cosleeping infants. Notably, these findings were not replicated when parental interventions as predictors of infant sleep were examined at later points in the first year.
Results inform conceptualizations of parenting competence in infant sleep contexts during the first few months of life and how best to promote infant sleep regulation across the first year.
婴儿期的睡眠质量对个人和家庭的健康都有影响[19]。在婴儿早期，父母的育儿方式可能对婴儿的睡眠模式和轨迹有很大的影响。
本研究使用观察和调查数据，调查了一个月和三个月时的睡眠安排以及两种夜间干预方式（非痛苦引发的和痛苦引发的）如何与婴儿在头九个月的睡眠发展相关。痛苦引发的干预被定义为父母对婴儿痛苦信号的反应，而非痛苦引发的干预则被定义为父母对非痛苦发声或婴儿入睡时的行为。
来自 107 个家庭的分析表明，婴儿夜间醒来的次数随着时间的推移而减少，这是预期的。早期非痛苦引发的干预与婴儿夜间醒来率变化之间的联系受到睡眠安排的显著调节，即独自睡眠的婴儿，如果经历了更高水平的非痛苦引发的干预，那么他们的婴儿夜间醒来率下降的速度就会比经历低水平非痛苦引发的干预的婴儿更慢。结果还表明，一个月和三个月时更高水平的痛苦引发的干预与独自睡眠和同睡的婴儿的婴儿夜间醒来率的急剧下降有关。值得注意的是，当以婴儿睡眠为预测指标来考察父母干预措施在第一年后期的作用时，这些发现并没有得到复制。
这些结果为婴儿生命最初几个月的睡眠环境中父母养育能力的概念化以及如何在第一年促进婴儿睡眠调节提供了信息。
