Wake windows at nine weeks are 60–90 minutes, and the day still holds 4–5 naps. What is new is that the first of them arrives at nearly the same time each day, often gets the longest stretch of daytime sleep, and is the easiest to put down for. Protect it. Do not schedule the pediatrician, the walk, or the visit from grandparents across the morning nap; that is where the day's best sleep lives right now.
After the morning nap, wake windows can be a touch longer, and the afternoon can be as messy as it likes.
Building around the anchor
- Note the morning wake time for a week. If it is roughly consistent (within 30–45 minutes), the first nap will be too.
- Put the first nap in the crib when you can. It is the most sleep-ready moment of the day, so it is the best place to practice crib sleep — and the nap that suffers least if it does not work.
- Let the afternoon be flexible. Carrier naps, stroller naps and contact naps are all fine in the afternoon; the point is total sleep, not location.
Why not fix the whole day yet
Because your baby's sleep cycles have not matured. Until roughly 3–4 months a nap ends whenever a cycle happens to end, so a "schedule" with fixed nap lengths would be fiction. What you can do now is stabilize the two things that are already stable — wake-up and first nap — and keep wake windows in range through the rest of the day. When cycles mature, the rest of the schedule snaps into place around what you have already built.
Schedules are averages.
Your baby isn't.
LunaLog learns your baby's actual rhythm from the naps you log and predicts the next nap window automatically — no mental math, and it updates itself as wake windows grow. Free to start, and both parents stay in sync in real time.
