Enter what your child actually does on a normal day. This checker compares it against the recommended range for their age from the AAP and the American Academy of Sleep Medicine.

The tool adds your child's night sleep (from the time they fall asleep to the time they wake) to their total daytime nap sleep, then compares that 24-hour total against the sleep-duration range recommended for their age. It does not store anything you type; the calculation runs entirely in your browser.
| Age | Recommended sleep per 24 hours | Includes naps? |
|---|---|---|
| 0 to 3 months | 14 to 17 hours | Yes |
| 4 to 11 months | 12 to 16 hours | Yes |
| 1 to 2 years | 11 to 14 hours | Yes |
| 3 to 5 years | 10 to 13 hours | Yes |
| 6 to 12 years | 9 to 12 hours | Night sleep |
| 13 to 18 years | 8 to 10 hours | Night sleep |
The 4-to-18 figures are from the American Academy of Sleep Medicine consensus statement (Paruthi et al., 2016), endorsed by the American Academy of Pediatrics. The 0-to-3-month figure is from the National Sleep Foundation panel (Hirshkowitz et al., 2015), as the AASM consensus did not set a formal recommendation for newborns.

These are population ranges, not targets for an individual child, and normal sleep need varies. Use the result as a prompt, not a diagnosis: a child who is consistently below the range and shows daytime signs of tiredness, or who is well above it and still seems exhausted, is worth discussing with your GP, health visitor or paediatrician.
