Baby sleep schedules by age

A sample day for each age, built from the same generator the planner uses and checked against published guidance. Every schedule is a shape to aim at, not a timetable — under about six months (corrected age) sleepy cues beat clock times every time.

Sample days

Newborn sleep schedule — 6 naps, 1 h 5 min each, bedtime 10:00 PM
1 month old sleep schedule — 5 naps, 1 h 20 min each, bedtime 9:00 PM
2 month old sleep schedule — 4 naps, 1 h 40 min each, bedtime 9:00 PM
3 month old sleep schedule — 4 naps, 1 h each, bedtime 7:00 PM
4 month old sleep schedule — 4 naps, 55 min each, bedtime 7:30 PM
5 month old sleep schedule — 3 naps, 1 h 10 min each, bedtime 7:00 PM
6 month old sleep schedule — 3 naps, 1 h 5 min each, bedtime 7:00 PM
7 month old sleep schedule — 2 naps, 1 h 45 min each, bedtime 7:00 PM
8 month old sleep schedule — 2 naps, 1 h 40 min each, bedtime 7:00 PM
9 month old sleep schedule — 2 naps, 1 h 25 min each, bedtime 7:00 PM
10 month old sleep schedule — 2 naps, 1 h 15 min each, bedtime 7:00 PM

Ages without a linked page above are still covered by the planner: it matches your baby's corrected age to the bracket it falls in and checks your schedule against it. For the awake stretches on their own, see wake windows by age.

Where these numbers come from

Tier 1 — evidence-based The ranges on this page are the consensus sleep totals and nap counts below. The phrase "wake window" itself is a Tier 2 practice-based heuristic: it does not appear in the pediatric sleep-medicine literature, so treat the window lengths as a starting estimate and let your baby's sleepy cues override them.
