Suggested bedtime
Sample day
Wake windows are a rough guide, not a rule. Watch for sleepy cues, such as yawning, rubbing eyes or fussing, and adjust. Always put your baby to sleep on their back.
How much sleep do babies need?
The American Academy of Sleep Medicine, supported by the AAP, recommends these totals in 24 hours, including naps:
- 4 to 12 months: 12 to 16 hours
- 1 to 2 years: 11 to 14 hours
Newborns often sleep 14 to 17 hours a day in short stretches. There is no official recommendation under 4 months because sleep patterns vary so much.
What are wake windows?
A wake window is the time a baby can comfortably stay awake between sleeps. It gets longer as babies grow. The ranges in this calculator are typical, not strict rules, so use them as a starting point and watch your baby’s sleepy cues.
Safe sleep
- Always place your baby on their back to sleep, for naps and at night.
- Use a firm, flat mattress with a fitted sheet and nothing else in the cot.
- Share a room, but not a bed, ideally for at least the first 6 months.
- Keep your baby away from smoke and avoid overheating.
