A 5-year-old needs 10 to 13 hours of sleep per 24-hour period, including any naps. This is the recommendation endorsed by the American Academy of Pediatrics, and it applies to all children ages 3 through 5. Most 5-year-olds get the bulk of that sleep at night, but some still benefit from a daytime nap.
Why the Range Is 10 to 13 Hours
Every child’s sleep needs are slightly different, which is why the recommendation is a range rather than a single number. A 5-year-old who sleeps 10 hours and wakes up energetic, focused, and in a generally good mood is getting enough. Another child the same age might genuinely need closer to 13 hours to function well. The National Sleep Foundation notes that an additional hour on either side of the range may even be appropriate for some individuals, so a child consistently sleeping just under 10 hours isn’t automatically cause for concern if they’re thriving during the day.
What matters more than hitting a precise number is paying attention to how your child behaves and feels. If they’re alert in the morning, can focus during activities, and aren’t melting down by late afternoon, their sleep total is likely in a healthy zone.
Do 5-Year-Olds Still Need Naps?
Some do, and some don’t. Research from the University of Massachusetts Amherst found that a child’s brain maturity, not their age, determines when they’re ready to drop naps. That’s why some 4- and 5-year-olds still nap like clockwork every afternoon while others stop napping as early as age 3. There’s no universal age cutoff.
If your 5-year-old still naps, those hours count toward the 10-to-13-hour total. If they’ve dropped naps entirely, they’ll need to get the full amount at night. A child who skips naps but only sleeps 9 hours overnight may be running a sleep deficit. On the other hand, if your child resists naps but seems cranky or unfocused by late afternoon, they may still benefit from quiet rest time even if they don’t fully fall asleep. Researchers emphasize that the opportunity to nap should be protected for children who still need it, because napping supports learning and memory at this age.
What Happens When a 5-Year-Old Doesn’t Sleep Enough
Sleep deprivation in young children often doesn’t look like sleepiness. It looks like behavior problems. A large NIH-funded study found that children who regularly got fewer than 9 hours of sleep per night had more impulsivity, anxiety, depression, and aggressive behavior compared to children with healthy sleep habits. They also performed worse on tasks involving decision-making, working memory, and learning. Brain imaging in the same study revealed that sleep-deprived children had less gray matter in brain areas responsible for attention, memory, and impulse control.
In day-to-day life, the signs of insufficient sleep in a kindergartner can include having a tough time waking up in the morning, acting hyperactive or noncompliant, overreacting to minor frustrations, difficulty paying attention, and acting impulsively. Sleep-deprived children also tend to see the world in a more negative light and have wider, more rapid mood swings in response to small events. Parents sometimes mistake these behaviors for personality traits or behavioral disorders when sleep is the underlying issue.
Sleep and Physical Growth
Growth hormone is released primarily during deep sleep. When sleep patterns are disrupted or cut short, growth hormone secretion drops, which can impair a child’s linear growth and physical development over time. This is one reason pediatric sleep recommendations are higher than what adults need. Your child’s body is doing significant building and repair work overnight, and that work requires adequate time in deep sleep stages.
Building a Bedtime Routine That Works
A consistent bedtime routine is one of the strongest predictors of good sleep in children. Research published by the American Academy of Sleep Medicine found that children with a nightly bedtime routine fell asleep faster, woke up less during the night, went to bed earlier, and slept longer overall compared to children without one. The routine itself doesn’t need to be elaborate. A bath, brushing teeth, and reading a bedtime story in the same order each night creates a behavioral chain that signals to your child’s brain that sleep is coming.
Consistency matters more than the specific activities. Doing the same sequence at roughly the same time each night, including weekends, helps anchor your child’s internal clock. If your 5-year-old needs 11 hours of sleep and has to wake up at 6:30 a.m., that means being asleep by 7:30 p.m., which means starting the bedtime routine around 7:00.
Screens Before Bed
Blue light from tablets, phones, and TVs suppresses the sleep hormone melatonin. In one study, two hours of exposure to an LED tablet reduced melatonin levels by 55% and delayed the onset of sleepiness by an average of 1.5 hours compared to reading a printed book. Young children’s eyes may be even more sensitive to this effect than adults’. Limiting screen time in the hour or two before bed makes a measurable difference in how quickly your child falls asleep.
Room Environment
A dark or dimly lit room, minimal noise, and a temperature between 68 and 72 degrees Fahrenheit create the best conditions for sleep. If your child’s room runs warm in summer or they tend to kick off covers, adjusting the thermostat or using lighter bedding can help them stay asleep through the night.
Signs That Something Else Is Going On
If your child is getting 10 or more hours of sleep and still seems chronically tired, inattentive, or moody, a sleep disorder could be interfering with sleep quality. Pediatric obstructive sleep apnea affects some children this age and is worth considering if you notice any of these during sleep: snoring on most nights, pauses in breathing, gasping or choking sounds, restless tossing, heavy mouth breathing, or unusual nighttime sweating. Bed-wetting that starts after a long stretch of dry nights can also be a sign.
During the day, children with sleep apnea may get morning headaches, breathe through their mouth habitually, have trouble learning or paying attention, or fall asleep on short car rides. Not all children with sleep apnea snore, especially younger ones, so disturbed or restless sleep alone is worth mentioning to your child’s pediatrician.
