Eleven months is the last month of the "two naps, no argument" era for most babies. Wake windows are pushing three and a half hours, daytime sleep is down to around two and a half, and the morning nap is doing less work than it used to.
Wake at 7:00 AM, 2 naps of about 1 h 10 min each, bedtime at 7:00 PM. Nap times are windows, not deadlines — anywhere inside one counts.
| Part of the day | Clock time | Notes |
|---|---|---|
| Wake | 7:00 AM | |
| Nap 1 | 10:00–11:10 AM | 3 h awake first |
| Nap 2 | 2:25–3:35 PM | 3 h 15 min awake first |
| Bedtime | 7:00 PM | 3 h 30 min awake first |
The planner adjusts it to your baby's own wake time, bedtime, and birthday — including corrected age if your baby was born early.
The sample day above lands at 2.25 h of daytime sleep and 12 h overnight — 14.25 h in 24. A baby at the bottom of the range who wakes up happy is not short on sleep; the range is wide because babies are.
The 2-to-1 nap transition is coming, but typically not for another two to seven months. False starts are normal: a week of refused morning naps followed by a month of needing them again.
Usually not. Most babies transition between 13 and 18 months. Readiness looks like weeks of consistently refusing or sleeping through one of the naps, not a bad fortnight.
2–3 hours during the day and 10–12 hours at night. That is the same bracket as 9 and 10 months — the change at this age is in the wake windows, not the totals.
Often the last wake window is now too short. As the windows stretch, a bedtime that used to be right becomes early, and an under-tired baby resists exactly like an overtired one.
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.
