“…Although many studies have been conducted on college or university students and worker samples, only a few have focused on families. Many studies were based on neonatology or the very first months of the child's life and the association with mother's and father's sleep and biological rhythms (e.g., de Roquefeuil et al, 1993;Feldman, 2006;Nishihara et al, 2002;Wulff & Siegmund, 2002;Yamazaki, 2007). Another group of studies was organized longitudinally and examined the changes between, for example, antepartum and postpartum measurements (see, e.g., Yamazaki et al, 2005a).…”

Different factors have been proposed to influence morningness-eveningness, biological rhythms, and sleep-wake cycles, but few studies focused on the influence of social habits. Here, we focus on the influence of children and partners on the social habits of women at different stages of their lives and on synchronization within the family. One hundred and seventy-nine women participated in the study and were allocated into four groups: women without children, pregnant women without children, pregnant women with children, and non-pregnant mothers. Morningness was predicted by the presence of children, and earlier chronotype was predicted by the presence of children, pregnancy, and age. Average sleep duration was longest in pregnant women. The presence of children was responsible for a difference in rise times of approximately 1.5 h on the weekend. Subjective sleep-onset latencies were shortest in women with children. The synchrony between partners (husband/wife) was 0.46 in women without children, 0.79 in pregnant women, 0.40 in women with children, and 0.56 between mother and child. Partners' chronotypes were highly correlated, as were those of mother and child. This study suggests children have a strong influence on their mother's lifestyle and sleep-wake rhythm, far beyond the first months of life, and that children are a more important social factor than the male partner.

“…However, research on young children is scarce, and some aspects have not been addressed sufficiently in previous work, such as the differences between weekdays and weekends, changes in chronotype, the developmental timing of social jet lag (Wittmann et al 2006) and some aspects of parental behaviour (but see exemptions below). Research on sleep spans from neonates over the group of toddlers and infants (Reynolds and Mallay 1933;de Roquefeuil et al 1993;Kelmanson 2004;Scher et al 2004;Acebo et al 2005), primary school children (Foster 1928;Mantz et al 1995;Owens et al 2000;Sadeh et al 2002) and, finally, adolescents (Carskadon et al 1993(Carskadon et al , 1998Tynja¨la¨et al 1993;Teixeira et al 2007;Loessl et al 2008;Randler 2008). A few pioneering studies spanned the time between infancy and adolescence and have been organized as longitudinal studies (Andrade et al 1993; Thorleifsdottir et al 2002;Iglowstein et al 2003;Scher et al 2004;Jenni et al 2007).…”

In this study, parents of pre-school children (0-6 years) answered an online questionnaire (444 girls, 447 boys). Children's bedtimes are earlier before weekdays and later before weekend days, and this difference becomes greater with age suggesting an increasing social jet lag at an early developmental stage. Half of the children have a sleep-onset latency of 15 min or shorter. When asked for children's optimal wake/bedtimes, parents would prefer later weekend rise times but earlier bedtimes both during the week and the weekend. Weekday rise times are determined by bedtimes during the week, awakening of children, parents' schedule and working hours per week. Bedtimes are determined by daytime napping, parental setting of bedtimes, and parental efforts for earlier bedtimes, parental efforts for regular bedtimes and by parental age. Chronotype changes and misalignment occurs at an early developmental stage, suggesting that parental influence exists and has an impact on the sleep-wake cycle (e.g. delaying of bedtimes at the weekend). We encourage parents to maintain a stable bedtime to avoid misalignment.

“…It is known that nocturnal sleep consolidation occurs at around the age of 5 months, 1,2 while a progressive sleep schedule delay is observed during adolescence. 3 How do sleep schedules change during childhood?…”
