Insights
Parenting strategies and sleep arrangements impact infant sleep development. Early distress-initiated interventions promote faster night waking reduction, while non-distress-initiated interventions show varied effects based on sleep location.
Area of Science:
- Developmental Psychology
- Pediatric Sleep Medicine
- Family Studies
Background:
- Early life sleep quality significantly impacts infant and family well-being.
- Parenting practices in early infancy may shape infant sleep patterns and developmental trajectories.
Purpose of the Study:
- To investigate the association between infant sleep arrangements and nighttime interventions (non-distress-initiated and distress-initiated) with infant sleep development.
- To examine these associations across the first nine months of life, focusing on early infancy (one and three months).
Main Methods:
- Utilized observational and survey data from 107 families.
- Analyzed nighttime parental interventions categorized as distress-initiated or non-distress-initiated.
- Examined the influence of sleep arrangements (solitary sleeping vs. cosleeping) on infant sleep outcomes.
Main Results:
- Infant night wakings decreased over the first nine months.
- Early distress-initiated interventions were linked to a steeper decrease in night wakings for both solitary and cosleeping infants.
- The effect of early non-distress-initiated interventions on night waking reduction was moderated by sleep arrangement, with solitary sleepers showing less improvement when interventions were high.
Conclusions:
- Findings inform parenting competence in infant sleep contexts during early infancy.
- Early parental interventions, particularly distress-initiated ones, are crucial for promoting infant sleep regulation in the first year.
Background:
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.
Method:
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.
Results:
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.
Conclusions:
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.

Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
