A 5-year-old needs 10 to 13 hours of sleep per 24-hour period, including any naps. That recommendation comes from the National Sleep Foundation and is used by the CDC as the benchmark for preschool-aged children (3 to 5 years). Most of that sleep will happen at night, but some 5-year-olds still nap, and that’s perfectly normal.
Why That Range Is So Wide
Ten to 13 hours is a broad window because children vary. A 5-year-old who still naps for an hour at preschool might sleep 10 hours at night and hit 11 total. Another who dropped naps entirely might need a solid 11 or 12 hours overnight. Both are fine. The key number to watch is the total across the full day, not just what the clock says at bedtime and wake-up.
The transition from napping to all-nighttime sleep happens anywhere from age 2 to as late as age 8, with enormous individual variation. If your 5-year-old still naps on some days but not others, they’re in the middle of this shift. You may notice they need an earlier bedtime on days they skip a nap, which is a simple way to keep total sleep in range.
What Happens While Your Child Sleeps
Sleep isn’t downtime for a growing body. Growth hormone is actively released during both stages of deep sleep, driven by a carefully timed cycle of signals deep in the brain. During sleep, growth hormone slowly accumulates, eventually helping trigger wakefulness when the body has had enough rest. This feedback loop is essential for bone and muscle development, tissue repair, and metabolic health. In other words, your child is literally growing in their sleep.
Beyond physical growth, sleep consolidates everything your child learned that day. Memory, attention, learning, and emotional regulation all depend on adequate rest. The brain of a 5-year-old is doing extraordinary work, and sleep is when much of that work gets locked in.
Signs Your Child Isn’t Getting Enough
Sleep-deprived kids don’t always look tired. In fact, they often look the opposite. A large CDC analysis of over 112,000 children found that short sleep duration (under 10 hours for 3- to 5-year-olds) is associated with problems in attention, behavior, learning, memory, and mental health. In young children, insufficient sleep commonly shows up as:
- Hyperactivity or impulsiveness rather than the sluggishness you’d expect
- Emotional meltdowns over minor frustrations, especially in the late afternoon
- Difficulty paying attention or following directions at school
- Resistance to waking up in the morning or falling asleep during short car rides
If your child consistently seems wired, weepy, or unfocused, sleep quantity is one of the first things worth examining before assuming a behavioral issue.
Building a Bedtime Routine That Works
A consistent bedtime routine is one of the most effective tools for improving a child’s sleep. Research from the American Academy of Sleep Medicine found that children who followed a nightly bedtime routine slept more than an hour longer per night compared to children who never had one. They also fell asleep faster, woke up less during the night, and went to bed earlier.
The routine itself doesn’t need to be complicated. A bath, brushing teeth, and a bedtime story in the same order each night creates a behavioral chain that signals the brain to wind down. What matters most is consistency: the more nights per week you maintain the routine, the better the results. Starting the routine earlier in childhood also helps, but it’s never too late to begin one.
Aim for roughly the same bedtime every night, including weekends. If your child needs to wake at 7 a.m. for school and doesn’t nap, a bedtime between 7 and 8 p.m. puts them in the 11- to 12-hour range. Adjust based on how easily they wake up and how they behave during the day.
Setting Up the Bedroom
Keep the room cool. A temperature between 68 and 72 degrees Fahrenheit is a comfortable range for young children. The room should be as dark as possible, since even dim light (about twice the brightness of a typical night light) can interfere with melatonin production and disrupt circadian rhythms.
Screens are a particular problem at bedtime. Blue light from tablets, TVs, and phones suppresses melatonin more powerfully than other types of light, making it harder to fall asleep. Harvard Health recommends avoiding bright screens two to three hours before bed. For a 5-year-old with a 7:30 bedtime, that means screens off by 5:00 or 5:30 p.m. at the latest. Swapping screen time for books, drawing, or quiet play in the hour before the routine starts makes a noticeable difference in how quickly your child falls asleep.
When Sleep Problems May Be Medical
Some children get the right amount of sleep and still seem poorly rested. Pediatric obstructive sleep apnea is more common than many parents realize, and it doesn’t always involve loud snoring. During sleep, watch for 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, struggle with attention and learning, act impulsive or aggressive, or fall asleep on short car rides. Enlarged tonsils and adenoids are a common cause at this age. If your child snores regularly or shows several of these signs despite getting enough hours in bed, it’s worth having their breathing evaluated during sleep.
