A recent Sleep in America® Poll by the National Sleep Foundation (NSF) took a national look at how young children in the U.S. are sleeping and how that sleep is woven into everyday family life.
“We wanted to understand not only whether children are getting the amount of sleep the NSF recommends, but also how parents think about sleep, what bedtime routines they rely on, and how children’s sleep relates to mood, behavior, and family functioning,” National Sleep Foundation SVP of Research and Scientific Affairs, Dr. Joseph Dzierzewski told us. “What emerged is a picture of families who place a high value on sleep but face real, ongoing obstacles.”
Young children have been underrepresented in national sleep surveillance, despite the fact that early childhood is a period of rapid brain development and intense family involvement.
“We chose this topic because children’s sleep is inseparable from family sleep health. When a child sleeps well, the whole household benefits. When they struggle, everyone feels it,” Dr. Dzierzewski told us. “By focusing on ages 0–13, we were able to capture the full arc of early development, from infants who rely entirely on caregivers to school-aged children who are gaining independence but still need structure.”
Many children do not consistently reach NSF sleep duration guidelines, parents commonly underestimate how much sleep kids need, and bedtime routines range widely in structure and intensity. At the same time, an overwhelming majority of parents see sleep as essential to their child’s mood, behavior, and daily functioning and say that their child’s sleep spills over into their own wellbeing.
« We hoped to illuminate the emotional and cognitive sleep management parents invest in managing sleep, and the poll shows that this effort is both substantial and deeply tied to family health, well-being, and functioning,” Dr. Dzierzewski told us.
The researchers anticipated finding a gap between what children need and what families are able to achieve, given the pressures of modern family life. They also expected that parents would strongly endorse the importance of sleep but might feel unsure about how much sleep is ideal at each age or how best to support healthy sleep. Another expectation was that children’s sleep problems would ripple outward, affecting parents’ own sleep, stress, and sense of how well the household is functioning.
The researchers adapted NSF’s validated measurement tools, the Sleep Health Index®, Sleep Satisfaction Tool®, and Best Slept Self ® Questionnaire, so parents could report on their children’s sleep. They paired these structured measures with detailed questions about routines, behaviors, and family experiences. This allowed the research team to test their assumptions from multiple angles: objective indicators of sleep health, parents’ subjective impressions, and the practical realities of daily life.
The results showed that sleep duration is a major challenge.
« The poll confirmed these broad patterns, but it also highlighted nuances we could not have predicted ahead of time, for example, just how frequently parents underestimate sleep needs, and how much time they devote to thinking about their child’s sleep on a typical day,” Dr. Dzierzewski told us. “We observed a ‘developmental sleep gap’ in which nearly half of children aren’t hitting the marks necessary for optimal emotional regulation and cognitive growth. »
The research team also found that parents underestimate sleep needs. From infants to young teens, there is a consistent disconnect between what science recommends and what parents believe is enough. Naps remain essential. For nearly a third of school-aged kids, napping is no longer a luxury, it is likely a necessary recovery tool for lost nighttime rest.
“We observed that bedtime routines are diverse,” Dr. Dzierzewski told us. “Families use a mix of environmental cues, soothing activities, and parental presence to help children settle.”
Another emerging theme was that sleep affects the whole family. Most parents say their own sleep suffers when their child sleeps poorly, and nearly all agree that sleep is central to family functioning.
“Parents think about sleep a lot, but talk about it less,” Dr. Dzierzewski told us. “Many spend hours each day thinking about their child’s sleep, yet nearly half rarely discuss sleep with their child.”
Two findings in particular stood out to researchers.
“First, the degree of underestimation of children’s sleep needs was striking,” Dr. Dzierzewski told us. « Parents were often off by more than an hour, with parents of newborns underestimating sleep needs by over three hours.”
Second, the emotional and cognitive load parents carry around sleep was higher than expected. Spending more than two hours a day thinking about a child’s sleep reflects how central, and how stressful, sleep can be for families. The fact that parents spend over two hours a day thinking about sleep shows that for many, bedtime isn’t just a chore, it’s a significant source of daily mental health strain. These insights highlight that parents are trying incredibly hard, often without enough support or clear guidance.
“The results point to a major opportunity,” Dr. Dzierzewski told us. “Families are motivated, but they need clearer, more accessible guidance. If we can help parents understand age-appropriate sleep needs, build sustainable routines, and feel confident talking with their children about sleep, we can shift the trajectory of family wellbeing.”
The data also reinforce that sleep interventions shouldn’t focus solely on the child, they should be family-centered, developmentally informed, and designed to reduce the mental load parents carry.
« We need to transition sleep from a nightly negotiation into a shared pillar of family wellness, » Dr. Dzierzewski told us. « Sleep is not only a biological need, it is also a family practice that unfolds within relationships, routines, and environments shaped by adults. Children learn what good sleep looks like from the cues they receive, bedtimes, wind down rituals, and the emotional tone around sleep in their home.”
When parents and caregivers are equipped with practical tools, accessible education, and compassionate guidance, they can do more than improve nighttime sleep, explained Dr. Dzierzewski.
“They are strengthening the emotional fabric of family life, making space for better mood, learning, and resilience during the day, and supporting healthier sleep patterns that can carry into adolescence and beyond.”
