Psychology says kids’ sleep habits aren’t shaped by biology alone: Research shows family culture plays a major role in when children sleep and how long they rest

Children's sleep patterns are shaped more by family culture than biology, a 2026 study reveals. Across Western communities, significant variations in bedtime, duration, and co-sleeping practices emerged, linked to parents' beliefs about healthy sleep. Research highlights that consistent bedtime routines, rather than specific activities or arrangements, are key to good sleep, suggesting a universal "correct" bedtime culture doesn't exist. Stable, family-adapted routines are more crucial than adhering to external norms.
