9 month old sleep: schedule, naps & wake windows
At 9 months sleep usually gives you a break: 2 solid naps, 3–4 hour windows and longer nights. It’s a great age to polish the routine and watch any leftovers of the 8 month regression fade away.
How much sleep does a 9 month old need?
Between 13–15 h in total across the day: about 10–12 h at night and 2.5–3 h during the day, spread over 2 naps. These are guide ranges: if your baby wakes rested and cheerful, they’re probably getting what they need. Compare all stages in the baby sleep chart by age.
Wake windows at 9 months
The wake window at 9 months is 3–4 h: the time they can comfortably stay awake before needing sleep again. Overshooting the window usually means overtiredness, crying and shorter naps; undershooting means bedtime resistance. The first window of the day is usually the shortest and the last one the longest.

Naps at 9 months
Expect 2 naps of 1 – 1.5 h each. The typical structure: nap 1 around 10:00 am and nap 2 around 2:30–3:00 pm, both 1–1.5 hours. If the morning nap runs too long it can “steal” from the afternoon one: capping it at 1.5 hours is a good rule. Nap transitions and lengths by age are in the baby naps guide.
Sample schedule for a 9 month old
Based on a 7:00 am wake-up. Shift the times to your baby’s real wake-up, keeping the windows.
| Time | Activity |
|---|---|
| 7:00 | Wake up & breakfast |
| 10:00 | Nap 1 (1–1.5 h) |
| 11:15 | Awake, play & lunch |
| 14:30 | Nap 2 (1–1.5 h) |
| 15:45 | Awake, snack & walk |
| 18:30 | Dinner, bath & routine |
| 19:45 | Bedtime |
With 3–4 hour windows, small 15–20 minute deviations break nothing: adjust as you go.
What time should bedtime be?
The usual range at 9 months is 7:00–8:00 pm. More than a fixed time, what matters is the window from the end of the last nap. A short, repeated bedtime routine (bath, pyjamas, story or song) helps them anticipate that sleep is coming.
