Infant sleep arrangements, infant-parent sleep, and parenting during the first six months post-partum.

The present study of 124 families examined linkages between patterns of sleep arrangement use across the first 6 months post-partum and (a) family socio-demographics, (b) nighttime sleep of infants, mothers, and fathers, and (c) coparenting distress, and mothers' emotional availability with infants and bedtime. Families were recruited when infants were 1-month-old, and infants were classified, from video data available at 3 and 6 months post-partum, into one of three sleep arrangement pattern groups: Solitary sleep, cosleeping, and cosleeping (at 3 months)-to-solitary sleep (at 6 months). Mothers in cosleeping arrangements were more likely to be at higher socioeconomic risk, non-White, unemployed, and to have completed fewer years of education.

Coparenting-focused preventive intervention reduces postnatal maternal BMI and buffers impact of cortisol.

Objective: The postpartum period is a key life stage, contributing to increased maternal obesity risk. Current lifestyle interventions do not consider the role of a woman's partner in reducing stress and supporting lifestyle change. The objective of this study was to assess the effect of an intervention that seeks to enhance coparenting relationship quality on maternal BMI from before conception to 12 months post partum and whether the intervention moderated the association of changes in cortisol and BMI.

Household chaos mediates the link between family resources and child sleep.

Purpose: This study examined the mediational role of household chaos in the link between family resources and child sleep outcomes during the transition to kindergarten.

Procedures: Participants included 230 families of children entering kindergarten (50% female) who participated in an 8-day measurement burst at pre-kindergarten (July-August), early kindergarten (September/October), and mid-kindergarten (November/December). At pre-kindergarten, mothers completFed the Family Resources Scale-Revised (FRS-R), while at pre- and early-kindergarten, trained observers assessed household chaos using the Descriptive In-Home Survey of Chaos-Observer ReporteD (DISCORD).
