How much sleep is recommended?

Sleep needs change as children grow. For primary school-aged children, the American Academy of Sleep Medicine recommends that children aged 6 to 12 should sleep 9 to 12 hours per 24 hours.[1]

In the UK, the NHS notes that most children aged 5 to 11 years need 9 to 11 hours of sleep each night.[2] Every child is different.[2] Some children need a little more sleep, and some need a little less.[2]

Why sleep matters

Sleep is not just rest. The NHS explains that sleep helps children's bodies and brains grow and stay healthy.[2] Good sleep helps children pay attention, behave well, learn new things, and remember what they learn.[2]

A worked bedtime example

If your child's school starts at 8:30 am and they need to be up by 6:30 am:
- For 11 hours of sleep: asleep by 7:30 pm
- For 10 hours of sleep: asleep by 8:30 pm
- For 9 hours of sleep: asleep by 9:30 pm

Add 15 to 30 minutes for the bedtime routine (bath, story, lights out). Choose a time that fits your family and stick to it.[2]

What parents can try

Here are simple ways to help your child sleep well.

- Go to bed and wake up at the same time each day.[2] Try to keep the same routine at weekends and in school holidays.[2]
- Have a calm bedtime routine: a bath or shower, quiet time with a parent, reading a story, then lights off.[2]
- Turn screens off one hour before bedtime.[2] Do not have screens in the bedroom.[2]
- Keep the bedroom quiet, dark, and safe.[2]
- Avoid fizzy drinks, sweets, and tea in the afternoon and evening.[2]
- If your child is hungry before bed, offer a small healthy snack such as yogurt, fruit, nuts, eggs, or whole-grain foods.[2]
