A 5-year-old needs 10 to 13 hours of sleep per 24-hour period. Most of that will come from nighttime sleep, since the vast majority of children have stopped napping by age 5. If your child is getting less than 10 hours consistently, you’ll likely notice it in their behavior, attention, and mood well before they complain about being tired.
Why the Range Is 10 to 13 Hours
The 10-to-13-hour recommendation covers ages 3 through 5, and where your child falls within that range depends on their individual biology. Some 5-year-olds genuinely thrive on 10 hours, while others are noticeably better with 11 or 12. The simplest way to tell is to watch what happens on mornings when your child wakes up naturally, without an alarm or a parent rousing them. If they’re sleeping about 10.5 to 11 hours on their own, that’s likely their sweet spot.
Naps at Age 5: Mostly Done
By age 5, roughly 94% of children have stopped napping entirely. If your child still naps occasionally, that’s not a problem, but it’s no longer expected. The transition away from naps happens gradually during the preschool years, with huge variation from child to child. At age 3, anywhere from 5% to 65% of children have already dropped naps. By age 4, that range jumps to 27% to 78%. By the time kids hit 5 and start school, napping becomes uncommon, with only about 8% of children continuing.
If your 5-year-old still seems to need a nap most days, it’s worth looking at whether they’re getting enough total nighttime sleep. A child consistently sleeping only 8 or 9 hours at night may compensate with daytime sleep, which can then push bedtime later and create a cycle that’s hard to break.
Signs Your Child Isn’t Sleeping Enough
Sleep-deprived 5-year-olds don’t usually say “I’m tired.” Instead, the signs look a lot like behavioral problems. Children who consistently sleep too little show measurable impairments in short-term and working memory. They struggle with attention and are more easily distracted, often displaying symptoms that look remarkably similar to ADHD: inattention, impulsivity, and hyperactivity.
The emotional effects are just as striking. Shorter sleep is correlated with more rule-breaking, more aggression, and higher rates of anxiety and depression, even in young children. Preschool and kindergarten teachers report more behavioral problems in kids whose parents also report sleep difficulties at home. If your child’s teacher mentions that they’re having trouble sitting still, following directions, or managing their emotions, insufficient sleep is one of the first things worth examining.
Building a Bedtime Routine That Works
A consistent bedtime routine is one of the most effective tools for improving a young child’s sleep, and the research is specific about what “consistent” means. The routine should happen in the hour before lights out, follow the same steps each night, and include two to four calming activities: brushing teeth, putting on pajamas, and reading a book together are classic choices. Positive, low-key interaction between parent and child during this window matters more than the specific activities you choose.
Keep the whole routine between 20 and 40 minutes. Routines that stretch longer than 40 minutes tend to backfire, pushing bedtime later and cutting into total sleep. The goal is predictability, not an elaborate production. If you do the same three things in the same order most nights of the week, your child’s body starts winding down almost automatically.
Screens and the Melatonin Problem
Children’s eyes are more sensitive to artificial light than adults’ eyes, and this has a direct, measurable effect on sleep. When children are exposed to blue-enriched white light (the kind emitted by tablets, phones, and many LED fixtures), their bodies suppress melatonin, the hormone that signals it’s time to sleep, significantly more than adults’ bodies do under the same conditions. The cooler and brighter the light, the worse the effect. Children exposed to cooler-toned lighting also reported feeling less sleepy than those exposed to warmer light.
The practical takeaway: dimming the lights and switching off screens before bed makes a real difference for kids this age. Even warm-toned lighting can suppress melatonin in children if it’s bright enough, so keeping the house relatively dim in the lead-up to bedtime helps your child’s internal clock do its job.
Room Temperature and Sleep Quality
The temperature of your child’s bedroom has a clear effect on how well they sleep. Research tracking children’s sleep alongside their room temperature found that sleep quality peaks when the room is around 71 to 73°F (22 to 23°C). Rooms that were too hot or too cold both led to poorer sleep. If your child is restless at night or waking frequently, checking the thermostat is a simple first step.
A Note on Melatonin Supplements
Melatonin gummies and drops have become enormously popular for children, but the evidence supporting their use in typically developing kids is thin. Current medical consensus holds that behavioral strategies (a consistent routine, appropriate light exposure, a comfortable sleep environment) should come first. There is a lack of efficacy data for melatonin in children without neurodevelopmental conditions.
There’s also a safety concern worth knowing about. Melatonin is now the leading substance involved in unsupervised medication ingestion among children ages 0 to 5 in U.S. emergency departments, with cases increasing fivefold between 2009 and 2021. While 97% of those cases result in only minor effects, the trend underscores that these supplements should be stored carefully and used only when behavioral approaches haven’t worked. For children with autism spectrum disorder or similar conditions, small doses given 30 to 60 minutes before bedtime are sometimes recommended after a thorough sleep assessment.
What a Typical Schedule Looks Like
If your 5-year-old needs to wake up at 7:00 a.m. for school, working backward from an 11-hour sleep target means lights out by 8:00 p.m. A bedtime routine starting around 7:20 to 7:30 gives you that 30-to-40-minute wind-down window. On weekends, letting your child sleep until they wake naturally (without shifting bedtime by more than 30 to 60 minutes) helps you gauge whether they’re getting enough during the week.
The transition to kindergarten often means earlier mornings than your child is used to, so adjusting bedtime in the weeks before school starts, rather than all at once, makes the shift easier. Moving bedtime earlier by 15 minutes every few days is a gentler approach than a sudden one-hour jump.
