Sleep needs change significantly throughout childhood – and it is one of the most frequently asked questions among parents. Here is a clear overview based on recommendations from the American Academy of Sleep Medicine (AASM), plus the signs you should look out for.
A child aged 1-2 needs 11-14 hours of sleep per day, a child aged 3-5 needs 10-13 hours, a child aged 6-12 needs 9-12 hours, and a teenager aged 13-18 needs 8-10 hours. These figures represent the total time per 24 hours including naps and come from the American Academy of Sleep Medicine.
| Age | Daily sleep | Daytime nap |
|---|---|---|
| 1-2 years | 11-14 hours | 1-2 naps |
| 3-5 years | 10-13 hours | 0-1 nap |
| 6-12 years | 9-12 hours | No nap |
| 13-18 years | 8-10 hours | No nap |

AASM's recommendations are divided into age brackets – not single years – because the variation between two children of the same age can be large. The table above shows the official brackets. Below, we translate them into everyday life.
Note that these are total hours per 24-hour period – including any naps. A 3-year-old who naps for 1 hour at midday needs 9-12 hours of nighttime sleep.
11-14 hours per day. Most 1-year-olds sleep 10-12 hours at night and still take 1-2 naps; many transition from two naps to one around 15-18 months. For 2-year-olds, one midday nap is typically enough. Maintain consistent times – the body and brain learn the rhythm.
10-13 hours per day. Some 3-year-olds drop the nap entirely, while others keep it for 60-90 minutes. The most important thing is that the nap isn't too late – preferably finished by around 2 PM. Also read 3-year-old hard to put to bed if bedtime is a struggle.
A 10-year-old falls under the 6-12 years bracket and should sleep 9-12 hours per day. If the child needs to be up at 7 AM, this means a bedtime between approx. 7 PM and 10 PM – and for most 10-year-olds, 8-9 PM is the realistic range if the morning is to function without an alarm clock battle.
Work backwards from the time the child needs to get up. If the child gets up at 6:30 AM and you are aiming for 10 hours of sleep, the lights should be out at 8:30 PM – and the routine should begin approx. 30 minutes before. It is the end time for screens, not the start of the tuck-in, that determines if the math adds up.
A 12-year-old is still in the 6-12 years bracket: 9-12 hours. From age 13, the teenage bracket of 8-10 hours applies, so both a 13-year-old and a 14-year-old need at least 8 hours – and typically more. During puberty, the internal circadian rhythm shifts, so the child naturally becomes tired later; therefore, consistent wake-up times and a screen-free final hour become more important than ever.
If you recognize several of these, it may be worth moving bedtime 30 minutes earlier for 2 weeks to see the difference.
It's not just about bedtime – it's about how bedtime proceeds. A stressed, hurried 10-minute tuck-in without calm often leads to a long time falling asleep. A calm routine of approx. 30 minutes with a good bedtime story makes falling asleep significantly shorter for most children.

When the child is the hero of their own story, the brain shifts to a calm internal state. This is exactly the shift that makes falling asleep easier and sleep deeper. Flipr creates personalized bedtime stories of 5-15 minutes – enough to drift off, not enough to stay awake.
Sleep needs decrease gradually throughout childhood, but even a 12-year-old needs 9-12 hours, and a 14-year-old needs 8-10. If your child hits the recommended number and wakes up rested, you are on the right track. If not, start by moving bedtime 30 minutes earlier and introducing a consistent routine.
10-13 hours per day incl. naps according to AASM. Most 3-year-olds sleep 10-12 hours at night and potentially take a short nap that ends well before evening.
9-12 hours per day. If the child needs to be up at 7 AM, this typically corresponds to a bedtime between 8 PM and 9 PM to allow for 10-11 hours of sleep.
8-10 hours per day according to AASM's recommendation for 13-18-year-olds. Many teenagers get less because the circadian rhythm shifts during puberty – consistent wake-up times help.
Signs include difficulty waking up, mood swings, poor concentration, and hyperactivity in the evening. Try moving bedtime forward by 30 minutes for two weeks to see if it helps.
Most children drop their midday nap between ages 3 and 4. Some maintain a short quiet period without sleep up until age 5, which is also fine.
