Sleep is an important factor in child cognitive, socioemotional, and health outcomes; however, determinants of sleep patterns have been little studied. Our study uses nationally representative data from the PSID Child Development Supplement (n=2,554) to examine whether parental work schedules are associated with children’s sleep patterns. Using parent reports of the hours they work in a normal week, we find that primary caregivers’ (PCGs’) work hours are predictive of children’s sleep durations and wake-up times, even after controlling for a battery of background characteristics. Compared to children of non-working PCGs, children whose PCGs work part-time get significantly more sleep and have significantly later wake-up times; children whose PCGs work over-time get less sleep and have significantly earlier wake-up times. Timing of parental work is also predictive of children’s sleep patterns. Potential mediators and moderators—including child age and the presence or absence of a secondary caregiver—are tested.
