Wondering how many hours of sleep your child needs by age? Here's the short answer: between 1 and 3, most children need about 11 to 14 hours a day, naps included. Between 3 and 5, closer to 10 to 13 hours. From 6 to 9, around 9 to 12 hours. And from 10 to 14, about 9 to 11 hours. These are ranges, not rules carved in stone.
You've surely noticed that the older a child gets, the less they sleep. That's normal. A toddler spends a big part of the day asleep. A pre-teen can get through the whole day on one night. In between, everything shifts little by little — often without you really noticing.
In this guide, we give you a simple age-by-age chart with night and nap. We also explain why your child can fall outside the range without it being a problem, until what age a nap is still useful, how to spot that they're missing sleep, and what to do to help them get their quota back. We finish with the cases where it's better to talk to a doctor.
The sleep hours chart by age
Here are the benchmarks most children's sleep specialists give. The total includes night and naps. Treat them as a compass, not a stopwatch.
You'll see the range is wide. That's on purpose: two children the same age can have very different needs, and both be perfectly fine.
- Ages 1 to 3: about 11 to 14 hours a day. Night of roughly 10 to 12 hours, plus 1 to 2 hours of afternoon nap.
- Ages 3 to 5: about 10 to 13 hours a day. Night of roughly 10 to 12 hours; the nap shortens, then disappears for many children.
- Ages 6 to 9: about 9 to 12 hours a day, almost all at night. The nap is mostly gone, except when they're wiped out.
- Ages 10 to 14: about 9 to 11 hours a day, overnight. At this age, getting enough sleep becomes a real challenge with school and screens.
Why these hours are only benchmarks
These numbers are averages. Your child is unique, and their sleep need is their own. Some children are short sleepers: they sleep a bit less than the range and still wake up full of energy. Others are long sleepers: they need a good extra hour compared with their friends to feel well.
The best judge isn't the chart — it's your child. If they fall asleep without a fight, sleep through or nearly through, and wake up in a good mood and ready for the day, they've had enough, even if the total is a bit under or over the average.
On the flip side, a child who sleeps right in the range but is grumpy, struggles to get up, and drags through the morning may be missing sleep — or missing good-quality sleep. What you see in the morning says more than the number of hours.
Naps: until when?
A nap is real sleep that counts toward the day's total. For toddlers, it's precious: it prevents the overload of tiredness that often makes evening bedtime harder.
In general, the single afternoon nap holds up until around age 3. After that, many children drop it between 3 and 5, each at their own pace. There's no official age: some let go of the nap early; others still need it in kindergarten.
A good sign the nap is too long or too late: the child isn't sleepy in the evening and bedtime goes off the rails. In that case, shorten the nap a little, or move it earlier in the afternoon, rather than cutting it overnight.
Signs they're missing sleep
Sleep debt in a child doesn't always look like tiredness. A tired child can instead get wound up, become grumpy, or struggle to settle. It can be misleading.
Look at the whole day instead. Several of these signs coming back often mean it's worth adjusting sleep a little.
- They're very hard to wake in the morning and take a long time to get going.
- They're grumpy, cry over nothing, or get frustrated quickly during the day.
- They struggle to focus, at school or during quiet play.
- They fall asleep at odd moments: in the car, at the table, in front of a cartoon.
- They move a lot at night, wake often, or wake well before it's time and can't fall back asleep.
How to help them get their quota
Good news: you can do a lot to help a child sleep better with a few simple habits. Nothing complicated — just regularity and a reassuring frame.
The idea isn't to add more rules, but to make sleep easier for their body. Here's what works for most families.
Choosing the right pillow height by age
A detail many parents forget: pillow height should follow the child's age. A 4-year-old's neck doesn't have the same needs as a 12-year-old's. A pillow that's too big breaks neck alignment and bothers sleep.
At The Little Night, the pillow comes in three sizes by age, so the head is always well supported — neither too high nor too low.
Important: before age 1, a baby sleeps flat on their back, with no pillow or cushion. Add nothing to the crib. For a toddler, talk to your pediatrician first.
- Ages 1 to 3: height of 2 to 4 cm, size 50 × 30 cm.
- Ages 3 to 8: height of 4 to 6 cm, size 50 × 30 cm.
- Ages 8 to 14: height of 6 to 9 cm, size 54 × 32 cm.
When should you worry or see a doctor?
Most small sleep issues settle with time, a good rhythm, and a little patience. But some signs deserve a doctor's or pediatrician's advice — without dramatizing.
Talk to a healthcare professional if your child snores loudly and all the time, seems to stop breathing for a moment during sleep, complains of real pain, or if a major sleep problem sets in and lasts despite your efforts.
Likewise, if your child seems exhausted all day even though they sleep enough, a medical opinion can help clarify things. You know your child better than anyone: if something truly worries you, the doctor is the right person to talk to.
