Wake windows at seven weeks run 60–90 minutes, and most babies are on 4–5 naps. The shift worth noticing is at night: one long stretch of 4–6 hours becomes possible for many babies, and it is anchored to the start of the night. The rest of the night stays fragmented — feeds every 2–3 hours after the long stretch are normal and will be for months.
Follow the long stretch. If it starts at 8 PM, that is bedtime now, even if it feels early.
Letting bedtime drift earlier
Do not move bedtime by the clock; move it by the data. If your baby is consistently going down for the "night" at 9:30 and sleeping five hours, try starting the wind-down at 9:00 for a few nights. If the long stretch holds, try 8:30. An earlier bedtime with a long first stretch usually produces more total night sleep, not less, because it aligns with the deepest part of the emerging circadian rhythm. Stop nudging when the long stretch starts shrinking.
What not to do with the long stretch
Do not assume a 5-hour stretch means your baby is ready to "sleep through" or that you can drop the feeds after it — the second half of the night still runs on 2–3 hour cycles. And do not try to create the stretch by keeping your baby awake late; that produces an overtired baby who wakes more. The stretch is developmental. Your job is to notice when it arrives and put bedtime in front of it.
Schedules are averages.
Your baby isn't.
