Turn these windows into clock times
A newborn wake window is short — often shorter than the feed, the change, and the cuddle that fill it. In the first weeks many babies are ready to sleep again 35 to 60 minutes after waking, and the window includes every minute of that, feeding time included.
| Wake window | Length | Where it falls |
|---|---|---|
| Window 1 | 1 h | after morning wake-up |
| Window 2 | 1 h 15 min | between naps |
| Window 3 | 1 h 15 min | between naps |
| Window 4 | 1 h 15 min | between naps |
| Window 5 | 1 h 15 min | between naps |
| Window 6 | 1 h 15 min | between naps |
| Window 7 | 1 h 15 min | before bedtime |
The same day with clock times, naps and bedtime is on the Newborn sleep schedule page.
At this age the cues win, always. A newborn showing sleepy signs at 25 minutes is not off schedule, and one happily awake at 90 minutes does not need to be put down. The window is a rough expectation to plan around, not a target to hit.
Yes. The window is the entire awake stretch from opening their eyes to falling asleep again, and at newborn age the feed is usually most of it.
They lengthen gradually rather than in steps: roughly 35–60 minutes in the first few weeks, nearer 60–90 minutes by two months. Week-by-week charts imply a precision the evidence does not support.
Very common, and rarely a scheduling problem. Overtiredness makes settling harder, so the usual fix is a shorter next window rather than a longer 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.
