How much sleep does a baby need: sleep chart by age
Updated November 2, 2026 · Olly team
Summary: newborns sleep 14 to 17 hours a day; from 4 to 12 months, 12 to 16 hours (including naps); from 1 to 2 years, 11 to 14 hours; from 3 to 5 years, 10 to 13 hours. From 4 months on, the ranges come from the American Academy of Sleep Medicine (AASM), endorsed by the American Academy of Pediatrics; for newborns, from the National Sleep Foundation.
Sleep hours by age
| Age | Total in 24 hours | Typical naps |
|---|---|---|
| 0 to 3 months | 14 to 17 hours | Many, no fixed schedule |
| 4 to 12 months | 12 to 16 hours | 2 to 4 naps, going down to 2 |
| 1 to 2 years | 11 to 14 hours | 1 to 2 naps |
| 3 to 5 years | 10 to 13 hours | 0 to 1 nap |
| 6 to 12 years | 9 to 12 hours | Usually no nap |
The 0 to 3 months range comes from the National Sleep Foundation. The others follow the AASM recommendation. The total adds night sleep and every nap of the day.
How to tell if your baby is sleeping enough
- Add up all naps and night sleep over the last 24 hours and compare with the range for their age.
- Look at the week, not a single day: bad days happen; the average is what matters.
- Watch their mood: late-afternoon fussiness and trouble falling asleep can be signs of building tiredness.
- Write down the times. After a few days of logs, it's easy to spot the wake window that works for your child.
Wake windows: how long a baby can stay awake
Young babies stay awake only a short time between sleeps. That interval grows with age: around 1 hour in the first months and 4 to 6 hours around age 2. Following that window often makes bedtime easier.
How Olly helps with sleep
In Olly you tap Fell asleep and Woke up, and the app adds up the hours for you. The Sleep screen compares the last 24 hours with the range for your child's age and, with Premium, shows a next nap prediction learned from your child's routine and a weekly report written with AI. Sleep sounds (white noise, rain and shush) come with a timer; on Android they keep playing with the screen locked.

How many hours should a 6-month-old sleep?
12 to 16 hours in 24 hours, counting night sleep and naps, according to the American Academy of Sleep Medicine.
How much does a 1-year-old sleep?
11 to 14 hours a day, counting the night and naps. Many children this age take 1 or 2 naps.
At what age do kids stop napping?
It varies a lot. Most children drop the nap between 3 and 5 years old. If your child sleeps well at night and stays in a good mood without a nap, they probably don't need it anymore.

Yes. In Olly you log when your baby fell asleep and woke up, see the last 24 hours compared with the range for their age and, with Premium, get a next nap prediction.
