Your baby is about 3 months old. Some days have a rhythm, other days the naps are 30 minutes long and bedtime drifts all over the place. If you’ve searched 3 month old sleep schedule, you probably want to know what a normal day looks like at this age, how long your baby can stay awake, and whether you should be aiming for a fixed bedtime yet. Short answer: at 3 months a loose rhythm works better than a strict clock, and this page shows you what that rhythm can look like.
This page is part of our baby sleep schedule by age guide. Next in the series: the 4 month old sleep schedule, then the 6 month old sleep schedule.
Quick answer: 3 month old sleep schedule
- Rhythm, not a timetable: the American Academy of Pediatrics (AAP) says babies don’t have regular sleep cycles until about 4 months of age. A loose pattern is normal at 3 months.
- Naps: 4 to 5 naps a day is a common pattern at this age, and many naps are short. This is a typical range, not an official rule.
- Wake windows: about 1 to 1.5 hours awake between sleeps is a common rough guide, stretching a little longer toward 4 months. Your baby’s tired signs come first.
- Nights: the NHS says some babies sleep 5 to 8 hours or longer at night from about 3 to 6 months, but not all. Waking to feed is still common.
- Bedtime: there is no official bedtime for a 3-month-old. A short, calm routine at a similar time each evening is enough for now.
- Safety: on the back for every sleep, on a firm, flat surface with nothing else in the crib. Stop swaddling as soon as your baby shows any signs of trying to roll (AAP).
What changes around 3 months
Three months sits between the CDC milestone checklists for 2 and 4 months. By 2 months, the CDC list includes holding the head up during tummy time, smiling when you talk to or smile at your baby, and making sounds other than crying. By 4 months it includes holding the head steady without support and chuckling. Those changes show up in sleep too.
- Days and nights sort themselves out. Many babies are past the worst of day and night confusion by now, so the longest sleep usually falls at night.
- Sleep is still maturing. Because regular sleep cycles come at about 4 months (AAP), naps can still be short and unpredictable. That is a stage, not a problem you caused.
- Rolling may be close. The AAP notes that rolling can begin as early as 2 months. If your baby still sleeps swaddled, watch for the first signs and plan the switch. Our guides to when to stop swaddling and sleep sack vs swaddle walk you through it.
- Awake time gets more fun. The AAP suggests making daytime playtime: talking, reading and playing together during the day.
For everything else your baby may be doing now, see our 3-month milestones guide.
Sample 3 month old sleep schedules
These are examples, not targets. Start from the time your baby actually woke up, and move everything earlier or later from there. If your baby shows tired signs before the time in the table, follow your baby.
Short-nap day (5 naps)
| Time | What happens |
|---|---|
| 7:00 a.m. | Wake up, feed, diaper change, cuddle |
| 8:15 a.m. | Nap 1 (about 30 to 45 minutes) |
| 10:00 a.m. | Nap 2 (about 30 to 60 minutes) |
| 12:00 p.m. | Nap 3 (about 45 to 90 minutes) |
| 2:45 p.m. | Nap 4 (about 30 to 45 minutes) |
| 4:45 p.m. | Nap 5, a short catnap (about 20 to 30 minutes) |
| 6:45 p.m. | Bedtime routine: feed, diaper, swaddle or sleep sack, song |
| 7:00 to 8:00 p.m. | Asleep for the night (night feeds as needed) |
Longer-nap day (4 naps)
| Time | What happens |
|---|---|
| 7:00 a.m. | Wake up, feed, diaper change, play |
| 8:30 a.m. | Nap 1 (about 1 hour) |
| 11:00 a.m. | Nap 2 (about 1 to 1.5 hours) |
| 2:00 p.m. | Nap 3 (about 1 hour) |
| 4:30 p.m. | Nap 4, a short catnap (about 30 minutes) |
| 6:30 p.m. | Bedtime routine |
| 7:00 to 8:00 p.m. | Asleep for the night (night feeds as needed) |
Feeds aren’t fixed to the clock, because many 3-month-olds still feed on cue. For typical amounts at this age, see our baby feeding schedule by age.
How much should a 3 month old sleep?
| Sleep | Typical at 3 months | Where it comes from |
|---|---|---|
| Total in 24 hours | Varies a lot between babies | The AAP’s recommended range of 12 to 16 hours starts at 4 months |
| Longest night stretch | Some babies sleep 5 to 8 hours or longer, but not all | NHS, for babies about 3 to 6 months |
| Naps a day | Often 4 to 5 | Common pattern, not an official measure |
| Wake window | About 1 to 1.5 hours | Rough guide, not an official measure |
If your baby wakes up mostly content, feeds well and is growing as expected, they are usually getting the sleep they need, even if the day looks nothing like the tables above.
3 month old wake windows: the 3-signal check
Wake windows are a starting point, not an AAP measure. Before you put your baby down, run this quick check:
- Time: has your baby been awake about 1 to 1.5 hours? If it’s been much less, a short burst of play may help first.
- Tired signs: yawning, staring into space, rubbing eyes, pulling at ears, turning away from toys or faces. See our guide to baby cues.
- Mood: fussing that a feed or a diaper change doesn’t fix often means it’s time to wind down.
Two out of three is a good moment to start the nap routine. If your baby often fights naps, try starting a little earlier, because an overtired baby can find it harder to settle.
Common 3-month sleep worries
“My baby only naps for 30 minutes”
Very common at this age. Sleep cycles are still maturing, and many babies link them into longer naps over the coming months. If your baby wakes happy, the nap may simply be done. If they wake upset, a few minutes of gentle comfort in the crib may help them drift off again.
“My baby only falls asleep feeding or being held”
That is normal at 3 months. The AAP’s advice to put babies to bed drowsy instead of already asleep is aimed at babies 4 months and older, so there’s no need to force it now. If you’d like to start practicing, try one nap a day. More ideas in our guide to a baby who won’t sleep without being held.
“Is there a 3 month sleep regression?”
“Regression” isn’t a medical term. Because sleep cycles mature around 4 months, some babies’ sleep gets bumpier a little before that. Our guide to sleep regression at 4, 6 and 8 months explains what can help.
“My 3 month old is sleeping a lot more than usual”
Some days are simply sleepier than others. But a baby who is hard to wake, too sleepy to feed or has fewer wet diapers needs a call to your pediatrician (see below).
“Bedtime keeps moving”
At this age that’s fine. Keep the routine short and the same each evening, and let the time follow the last nap. A fixed bedtime may get easier once sleep cycles mature. Our baby bedtime routine guide has a simple plan. US clocks fall back on Sunday, November 1, 2026: see our daylight saving time baby sleep plan.
Night feeds and night wakings
Many 3-month-olds still wake at night, often to feed. The AAP suggests keeping night feeds and diaper changes calm and quiet: low light, soft voice, no play. This helps your baby learn that night is for sleeping. Feed when your baby is hungry; at this age there’s no need to stretch feeds to reach a schedule.
Safe sleep at 3 months
- Place your baby on their back for every sleep, naps included, until their first birthday (AAP). Side sleeping isn’t a safe alternative.
- Use a firm, flat surface in a crib, bassinet or play yard, with no blankets, pillows, bumpers or toys.
- Share a room, not a bed, ideally for at least the first 6 months (AAP and NHS).
- If your baby falls asleep in a car seat, stroller, swing or carrier, move them to a firm, flat sleep surface on their back as soon as you can (AAP). See is it safe for baby to sleep in a car seat and is it safe for baby to sleep in a swing.
- Swaddle only on the back, with room for the hips to move, and stop as soon as your baby shows any signs of trying to roll (AAP).

When to talk to your doctor
- Your baby is very sleepy, hard to wake or too sleepy to feed.
- Your baby has fewer wet diapers than usual or is feeding much less.
- Your baby is younger than 3 months (12 weeks) and has a temperature of 100.4°F (38°C) or higher: call your pediatrician right away (AAP). For older babies, see our guide to baby fever.
- You notice snoring, gasping or pauses in breathing during sleep.
- Your baby cries in a way that sounds unusual or can’t be comforted for long periods.
- You feel exhausted or low and it’s hard to cope. Your pediatrician can help or point you to support.
- Call 911 if your baby stops breathing, turns blue or gray, or can’t be woken.

Frequently asked questions
How many naps should a 3 month old take?
Many 3-month-olds take 4 to 5 naps a day. Babies with short naps often need 5, and babies with longer naps may do well with 4. This is a common pattern, not an official rule.
What are wake windows for a 3 month old?
About 1 to 1.5 hours between sleeps is a common rough guide. Wake windows are not an official AAP or NHS measure, so watch your baby’s tired signs as well.
How long should a 3 month old sleep at night?
There’s no official number for the night at this age. The NHS says some babies sleep 5 to 8 hours or longer at night from about 3 to 6 months, but not all. Waking to feed is still common and normal.
Should a 3 month old be sleeping through the night?
Not necessarily. Some do and many don’t, and both are normal. If your baby is feeding well and growing as expected, night waking at 3 months is not a sign that something is wrong.
What time should a 3 month old go to bed?
There’s no set bedtime. Pick a time that follows a reasonable wake window after the last nap, and keep the routine the same each evening. A fixed bedtime may feel easier from around 4 months, when sleep cycles become more regular.
Can I sleep train a 3 month old?
The AAP’s advice on putting babies to bed drowsy and letting them resettle is for babies 4 months and older. If you’re thinking about sleep training, talk to your pediatrician first and compare the options in our guide to sleep training methods.
