Age-related developments in sleep during the preschool years are normative and consequential. Yet, very few studies have examined the antecedents of individual differences in such developments, and most have used parental reports of child sleep. This study aimed to investigate the roles of mutual responsiveness in mother-child interactions and…

This study examined the reciprocal associations between sleep (duration and quality) and aggressive behavior in toddlers. The sample consisted of 82 children (43 boys and 39 girls) and their parents who completed two assessments, when children were 2 and 3 years old. At both time points, children wore an actigraph for 3 consecutive days to assess…

While maternal influences on young children's sleep are increasingly documented, the study of paternal contributions to this important sphere of child functioning is only just beginning. In addition, much of this emerging research has focused on infancy only or has relied on parental reports of child sleep. The current study aimed to examine the…

This study investigated the prospective links between sleep in infancy and preschoolers' cognitive performance. Mothers of 65 infants completed a sleep diary when infants were aged 1 year, and children completed two subscales of the Wechsler Preschool and Primary Scale of Intelligence at 4 years, indexing general cognitive ability and complex…

The aim of this study was to investigate the prospective relations between parental psychosocial functioning and toddlers' sleep consolidation. Investigators met with 85 families 3 times, when children were 15 months (Time 1 [T1]), 18 months (T2), and 2 years of age (T3). Mothers and fathers completed questionnaires pertaining to their parenting…

The current study aimed to examine infant sleep duration as a moderator of the relations between maternal sensitivity and child externalizing and internalizing symptoms, in a prospective longitudinal design. Fifty-five Caucasian infants (33 girls) took part in 2 assessments, at 1 and 4 years. Maternal sensitivity was rated at 1 year, based on…

The aim of this report was to investigate the prospective links between infant sleep regulation and subsequent executive functioning (EF). The authors assessed sleep regulation through a parent sleep diary when children were 12 and 18 months old (N = 60). Child EF was assessed at 18 and 26 months of age. Higher proportions of total sleep occurring…
