Three months is the bridge out of the newborn fog. Wake windows stretch to 75–105 minutes, naps begin consolidating toward four a day, and bedtime drifts earlier — often landing near 8 PM for the first time. You'll notice the morning nap become predictable before anything else; that's the anchor the rest of the day organizes around.
Short catnaps are still completely normal. Nap lengthening comes with the sleep-cycle maturation that happens over the next month or two.
Clock or cues?
Still cues — but the clock is becoming a useful assistant. Start watching for sleepy signs about 15 minutes before the wake window closes. If your baby reliably melts down before the window ends, shorten it; if naps take 20+ minutes of protest to start, lengthen it. Your baby's real window is discovered, not assigned.
Get ahead of the 4-month changes
Next month, sleep cycles restructure permanently (the famous "4-month regression"). You can soften the landing now: practice putting your baby down drowsy but awake for one nap a day, keep the bedtime routine identical every night, and make sure daytime feeds are full feeds so night wakings are less about hunger.
Schedules are averages.
Your baby isn't.
