A five-year-old needs 10 to 13 hours of sleep per 24-hour period, including any naps. That recommendation comes from the American Academy of Sleep Medicine and is endorsed by the CDC. Most five-year-olds get the bulk of that sleep at night, since fewer than 30% of children this age still nap regularly.
Why 10 to 13 Hours Matters
Sleep isn’t just rest for a growing child. During both stages of deep sleep, the brain triggers surges of growth hormone from a region deep in the hypothalamus. This hormone does exactly what the name suggests: it drives bone and muscle growth. But it also plays a role in attention, cognition, and the ability to seek out new experiences, because it activates an area of the brainstem involved in arousal and learning. The cycle works like a feedback loop. Sleep drives growth hormone release, and as growth hormone accumulates, it gradually nudges the brain toward wakefulness. That balance between sleep and waking is essential for growth, repair, and metabolic health.
In practical terms, a five-year-old who consistently sleeps less than 10 hours is missing out on full cycles of this process. Over time, the effects show up not just in physical growth but in how well the child learns, remembers, and regulates emotions.
What Insufficient Sleep Looks Like
Sleep-deprived five-year-olds rarely act the way tired adults do. Instead of getting drowsy and sluggish, they often become more hyperactive, impulsive, or aggressive. Parents sometimes mistake this for a behavior problem or even early signs of ADHD, when the real issue is not enough sleep. The relationship goes both ways: existing attention or anxiety issues can make falling asleep harder, and poor sleep makes those same issues worse.
Other signs to watch for include difficulty paying attention during activities they normally enjoy, morning headaches, increased clinginess or irritability, and trouble retaining things they’ve learned. If your child falls asleep on short car rides or during quiet moments at school, that’s a strong signal they’re not getting enough overnight sleep.
Napping at Age Five
At age three, nearly all children still nap daily. By four, about 60% still do. But by five, most children have dropped their nap entirely. If your five-year-old no longer naps, they need to get the full 10 to 13 hours at night. That means a child who wakes at 7 a.m. should be asleep by 9 p.m. at the latest, and ideally closer to 7:30 or 8 p.m.
Some five-year-olds still benefit from a short afternoon rest, especially during the transition to full-day school. If your child naps and still falls asleep easily at bedtime, the nap is fine. If the nap pushes bedtime later and later, it’s probably time to phase it out and shift that sleep to nighttime.
Building a Bedtime Routine
A consistent bedtime routine is one of the most effective tools for helping a five-year-old fall asleep on time. The ideal routine lasts about 30 minutes (a little longer if it includes a bath) and follows the same three or four steps every night. A typical sequence might look like this: a small healthy snack, brushing teeth, putting on pajamas, and reading a book together.
The key is consistency. Doing the same activities in the same order signals to your child’s brain that sleep is coming. Five-year-olds are old enough to take ownership of parts of the routine, like brushing their own teeth or tidying their room before bed. That sense of participation can reduce bedtime resistance.
In the lead-up to the routine, start dimming lights around the house and turning off screens. Bright screens suppress the body’s natural production of melatonin, the hormone that makes you feel sleepy. Harvard Health recommends avoiding bright screens two to three hours before bed. For a child with a 7:30 p.m. bedtime, that means screens off by 5:00 or 5:30 p.m. at the latest. That can feel like a big ask, but it makes a measurable difference in how quickly your child falls asleep.
When the routine ends, leave the room while your child is drowsy but still awake. This helps them learn to fall asleep independently, which also means they can resettle on their own if they wake during the night.
Setting Up the Sleep Environment
A cool, dark, quiet room helps children fall asleep faster and stay asleep longer. For young children, a room temperature between 60 and 68°F (roughly 16 to 20°C) is ideal. If your child is afraid of the dark, a dim nightlight is fine, but avoid bright or blue-toned lights that can interfere with melatonin production.
White noise machines can help mask household sounds, especially if your child’s bedtime falls while other family members are still active. Keep the bedroom associated with sleep: avoid using it as a play space or screen time area in the hours before bed.
When Sleep Problems May Be Medical
If your child is getting the recommended hours but still seems tired, irritable, or unfocused during the day, the quality of their sleep may be the issue. Pediatric obstructive sleep apnea is one common culprit. Nighttime signs include snoring, pauses in breathing, restless sleep, gasping or choking sounds, mouth breathing, and heavy sweating. Some young children with sleep apnea don’t snore at all but simply have very disturbed, fragmented sleep.
During the day, children with sleep apnea may breathe through their mouth, complain of morning headaches, have trouble learning or paying attention, or gain weight poorly. Bed-wetting that returns after a long dry stretch can also be a sign. If any of these patterns sound familiar, it’s worth bringing them up with your child’s pediatrician, since treatment can dramatically improve both sleep quality and daytime behavior.
