How much sleep children need by age

Children need much more sleep than adults, and it changes a lot as they grow. These are the widely used general guidelines (including naps for younger children):

  • Babies (4–11 months): about 12–15 hours
  • Toddlers (1–2 years): about 11–14 hours
  • Preschoolers (3–5 years): about 10–13 hours
  • School age (6–13 years): about 9–11 hours
  • Teenagers (14–17 years): about 8–10 hours

Tips for an easier bedtime

  • Keep a consistent routine β€” same steps, same times, every night.
  • Dim lights and switch off screens about an hour before bed.
  • A calm wind-down (bath, story, cuddle) signals the body it's time to sleep.

How many hours of sleep does a child need?

It depends on age β€” from about 8–10 hours for teens up to 11–14 for toddlers. Pick the age group above for a tailored bedtime.

What time should my child go to bed?

Work backwards from wake-up time. A 7-year-old waking at 7am and needing ~10 hours should sleep around 9pm. This tool does it for you.

Is this medical advice?
