RESUMEN
OBJECTIVES: The current study examined longitudinal linkages between child sleep duration and children's socioemotional, learning engagement, executive functioning, and academic outcomes across the full kindergarten (K) year. METHODS: A measurement-burst design was employed to examine 3 different measures of child sleep duration in 7-day bursts at pre-K (July-August), early K (late September), mid-K (late November), and late K (mid-to-late April), using wrist actigraphy. These measures included mean amounts of child sleep per 24-hour period across the full week, proportion of 24-hour periods per week that children slept 10 or more hours, and proportion of nighttime sleep periods per week that children slept 10 or more hours. Children's outcomes at early, mid-, and late K were provided by their K teachers blind to children's sleep histories, and by assessments administered by project staff. RESULTS: Among the 3 sleep measures examined, regularity of nighttime sleep in which children slept 10 or more hours per night, especially at pre-K, consistently predicted more favorable K outcomes in both socioemotional, learning engagement, and academic domains. Results suggested that establishing healthy nighttime sleep habits before K start was especially promotive of better K adjustment across the full K year. These findings were controlled for income-to-poverty threshold ratios, child health status, and number of missed school days. CONCLUSIONS: Efforts to promote a favorable transition to first-time schooling should pay particular attention to sleep hygiene and regularity of 10-plus hours of nightly child sleep established before the start of K.

The second year of life is a time of formative developmental change as basic behavioral systems undergo rapid integration and expansion. This study examined the developmental trajectories of social-emotional (SoE) outcomes and the effects of infant sex and household chaos (HC) on the development of SoE outcomes across the second year of life. The participating families (N = 143) were ethnically homogenous (88% Caucasian) but economically diverse (31% low-to-very-low income). Mothers reported on their children's SoE outcomes including externalizing, internalizing, dysregulating problem behaviors as well as SoE competence when infants (54% girls) were 12, 18, and 24 months old. At each age point, HC was assessed through observations during home visits and compliance to the study protocols. Multilevel modeling revealed increasing developmental trajectories in all of the domains of SoE outcomes across the second year of life, reflecting the premise that these behavioral systems continue to form and become increasingly part of the infant's behavioral repertoire as development unfolds. However, compared to infants in less chaotic homes, infants in more chaotic households experienced steeper increases in both externalizing and internalizing problem behaviors across the second year, and girls showed higher levels of internalizing problem behaviors compared to boys. Results emphasize the increasing trajectories of problem behaviors in relation to ongoing chaotic caregiving environment among infants as young as 2 years of age.

The present study examined both between- and within-person effects of maternal sleep patterns on quality of mothering at bedtime during infants' first 6 months. Participants included 142 mothers who reported on their daily fall asleep and wake times across seven consecutive days with a daily sleep diary when infants were 1, 3, and 6 months old. At each age point, maternal emotional availability during one night of infant bedtime was observed and scored by trained observers who were blind to maternal sleep patterns. Multilevel modeling revealed that mothers with irregular sleep patterns, especially later average fall asleep times and greater average variability in sleep period across three age points, showed poorer parenting quality with infants at bedtime than other mothers. In addition, both between- and within-person effects of maternal sleep on bedtime parenting quality changed with infant age. Compared to mothers' individual averages across 1, 3, and 6 months, maternal short average sleep period, increased variability in sleep period, and later fall asleep times predicted poorer bedtime parenting quality at 6 months, but not at 1 or 3 months. Results emphasize the importance of maternal sleep regulation and sleep hygiene for maternal parenting quality, especially as infants get older.

Household chaos has been linked with dysregulated family and individual processes. The present study investigated linkages between household chaos and infant and parent sleep, a self-regulated process impacted by individual, social, and environmental factors. Studies of relations between household chaos and child sleep have focused on older children and teenagers, with little attention given to infants or parent sleep. This study examines these relationships using objective measures of household chaos and sleep while controlling for, respectively, maternal emotional availability at bedtime and martial adjustment, in infant and parent sleep. Multilevel modeling examined mean and variability of sleep duration and fragmentation for infants, mothers, and fathers when infants were 1, 3, 6, 9, and 12 months (N = 167). Results indicated infants in higher chaos homes experienced delays in sleep consolidation patterns, with longer and more variable sleep duration, and greater fragmentation. Parent sleep was also associated with household chaos such that in higher chaos homes, mothers and fathers experienced greater variability in sleep duration, which paralleled infant findings. In lower chaos homes, parents' sleep fragmentation mirrored infants' decreasingly fragmented sleep across the first year and remained lower at all timepoints compared to parents and infants in high chaos homes. Collectively, these findings indicate that after controlling for maternal emotional availability and marital adjustment (respectively) household chaos has a dysregulatory impact on infant and parent sleep. Results are discussed in terms of the potential for chaos-induced poor sleep to dysregulate daytime functioning and, in turn, place parent-infant relationships at risk. (PsycINFO Database Record

Although parents' structuring of infant sleep is complexly determined, little attention has been given to parents' marital and personal adjustment in shaping sleep arrangement choices. Linkages were examined between infant sleep arrangements at 1 and 6 months and mothers' marital adjustment, co-parenting quality, and depressive symptoms. The final study sample was composed of 149 families (53% girl infants, 86% European American). Bed sharing mothers had lower co-parenting quality, and, at 6 months, more depressive symptoms than mothers of infants in solitary sleep. One-month co-parenting quality was associated with predictable shifts in sleep arrangements from 1 to 6 months, but 1-month sleep arrangements did not predict changes in personal or co-parenting quality. Findings emphasize the need for greater attention to marital and emotional health in influencing family-level decisions about infant sleep arrangements.

Household chaos is a construct often overlooked in studies of human development, despite its theoretical links with the integrity of individual well-being, family processes, and child development. The present longitudinal study examined relations between household chaos and well-established correlates of chaos (sociodemographic risk, major life events, and personal distress) and several constructs that, to date, are theoretically linked with chaos but never before assessed as correlates (quality of coparenting and emotional availability with infants at bedtime). In addressing this aim, we introduce a new measure of household chaos (the Descriptive In-home Survey of Chaos--Observer ReporteD, or DISCORD), wholly reliant on independent observer report, which draws from household chaos theory and prior empirical work but extends the measurement of chaos to include information about families' compliance with a home visiting protocol. Household chaos was significantly associated with socioeconomic risk, negative life events, less favorable coparenting, and less emotionally available bedtime parenting, but not with personal distress. These findings emphasize the need to examine household chaos as a direct and indirect influence on child and family outcomes, as a moderator of intervention attempts to improving parenting and child development, and as a target of intervention in its own right.
