9 Month Old Wake Windows & Sleep Schedule
A 9 month old usually handles wake windows of 3 to 4 hours on 2 naps. Many babies can now pull to standing, and a common sleep challenge is a baby who stands up in the crib and can't work out how to lie back down.

How 9 month old wake windows change through the day
The first wake window of the day is the shortest. Each one after a nap gets a little longer, with the longest just before bedtime:
| Window | Length |
|---|---|
| First window (after morning wake-up) | 3 h |
| After nap 1 | 3 h 30 min |
| Last window (before bedtime) | 4 h |
What's changing for your 9 month old
- Standing in the crib is common; practising getting down in the day helps.
- The first window of the day is often 3 hours, the last 3½–4.
- Some babies start pushing back on the morning nap.
- Object permanence makes goodbyes at bedtime harder for some babies.
What comes next
Wake windows stay around 3–4 hours through 11 months. Resist dropping to 1 nap before 13 months unless your pediatrician suggests otherwise.
