Baby sleep schedule at 3 months: four naps, wake windows and routine
Lulla TeamPublished Updated
Three months is the first real turning point. The reference range for total sleep eases down a little, to 13 to 16 hours a day — a bridge between the 14 to 17 hours of the first months and the 12 to 15 that apply from 4 months. Night sleep holds at 9 to 10 hours, and the daytime settles into 4 naps rather than a scattering of short ones. Wake windows now run 75 to 105 minutes, so your baby is awake for a meaningful chunk of the morning.
With four naps and longer awake stretches, a rough shape appears in the day for the first time. It's still a shape rather than a timetable — the naps drift, some run 30 minutes and some 90 — but you can finally hang a short bedtime routine on the end of it.

Does this 3 months schedule match your day?
Lulla times the naps and tells you when the wake window is closing, so you do not have to keep count in your head.
This is a good month to start a wind-down you can repeat anywhere: bath or wash, pajamas, a feed, a song or a short story, lights out. The order matters more than the content, because the sequence itself becomes the signal. Three or four steps is plenty. Done nightly, it does more for sleep at this age than any clock does, and it travels with you to the grandparents' house.
Short naps are the standard complaint at 3 months. Many babies wake at the 30 to 45 minute mark because that's roughly one sleep cycle, and linking cycles is a skill that develops over the following months. A dark room, a consistent pre-nap routine and a wake window that has not overshot 105 minutes give the best odds. If a nap stays short, shorten the next window slightly rather than pushing on.
A sample day
Here is one way a 3-month-old's day can fall, with 4 naps and wake windows of 75 to 105 minutes. Treat the times as a starting point, not a target: on a day when the first nap runs 25 minutes, everything after it moves earlier, and that is fine.
| Time | What happens |
|---|---|
| 7:00 | Wake-up and first feed |
| 8:30 | Nap 1 · approx. 60 min |
| 11:00 | Nap 2 · approx. 60 min |
| 13:45 | Nap 3 · approx. 45 min |
| 16:15 | Nap 4 · approx. 30 min |
| 19:30 | Bedtime routine and lights out |
A sample day to give you a rough idea — every baby is different. Adjust the times to your child's sleep cues, and talk to your pediatrician about anything that worries you.
Your baby's sleep schedule, by age
One table with everything that matters: total sleep per 24h, wake windows and number of naps, from newborn to age 3. Total sleep follows the National Sleep Foundation recommendations.
Tips for this age
- Stop swaddling at the first sign of rolling — if your baby is pushing up or turning onto their side, switch to a sleep sack with the arms free.
- Darken the room for daytime naps too; at 3 months light is starting to influence melatonin, and a dark room helps the short cycles link.
- Log the naps for a week in Lulla, because the pattern of which nap is reliably long and which is a catnap tells you where to put the routine.
- Keep the crib bare and your baby on their back, even now that they are stronger and starting to move — nothing loose before 12 months.
- Bring anything that unsettles you to the 4-month check-up: reflux, noisy breathing during sleep, or a baby who never seems rested.
