9 month old sleep schedule
At 9 months, most babies take 2 naps with wake windows of 3 h to 4 h, and need 12–16 h of sleep in 24 hours.

- 3 h – 4 h
- Naps a day
- 2
- Total sleep / 24 h
- 12–16 h
- Daytime sleep (sample)
- about 2 h 30 min
A 2-nap day with wake windows of about 3–4 hours is typical. Total sleep is still 12–16 hours in 24.
If the afternoon nap is getting pushed late, an earlier bedtime for a few weeks often helps.

Make it fit your baby
This schedule is built from the middle of the wake-window range for this age, with windows that lengthen through the day. If your baby fights naps, try stretching each window by 10–15 minutes; if they melt down before naps, shorten them. For a schedule from your baby's exact age, a sleep pressure clock and an AI helper for specific problems, use the baby sleep schedule calculator.
Feeding and sleep go together: see the 9-month-old feeding schedule for how much milk to expect at this age.
Safe sleep: the AAP recommends placing babies on their back on a firm, flat, empty surface, in the parents' room for at least the first 6 months.
