Baby sleep schedule at 5 months: three naps and longer wake windows
Lulla TeamPublished Updated
At 5 months your baby needs 12 to 15 hours of sleep a day, with 10 to 11 of those at night and the rest across 3 naps. Wake windows have settled at 2 to 2.5 hours, long enough that the day now has a genuine morning, afternoon and evening rather than a blur of feeds and sleeps.
Three naps is the headline change. After the four-nap sprawl of earlier months, most 5-month-olds consolidate into a morning nap, a midday nap and a short late-afternoon nap that mainly exists to protect bedtime. That structure is what makes the day feel manageable for the first time.

Does this 5 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.
With the 4-month reorganization behind you, sleep associations become the thing worth paying attention to. Whatever helps your baby fall asleep at bedtime is what they will look for when they surface between cycles at 1 am. That's not a reason to stop rocking or feeding to sleep if it works for your family — it's simply the mechanism behind most night waking at this age, and knowing it makes the pattern less mysterious.
Rolling usually arrives around now, and a baby who rolls onto their front in the night no longer needs to be turned back, provided they got there themselves and can roll both ways. What does not change is how you put them down: on their back, every time, in a crib with nothing loose in it. If your baby is still swaddled, that has to stop before rolling starts.
A sample day
This is one plausible 5-month day, built on 3 naps and wake windows of 2 to 2.5 hours. It's a sketch rather than a rule — the late-afternoon nap in particular is often short, and that's exactly what it is for.
| Time | What happens |
|---|---|
| 7:00 | Wake-up and first feed |
| 9:00 | Nap 1 · approx. 60 min |
| 12:15 | Nap 2 · approx. 75 min |
| 15:45 | Nap 3 · approx. 30 min |
| 19:15 | 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
- Aim to have the third nap finished by late afternoon, so it tops your baby up without eating into the last wake window before bedtime.
- Keep the room dark for the midday nap, which is usually the one with the most potential to run long.
- If your baby now rolls onto their front in sleep, leave them there — but keep putting them down on their back, and keep the crib empty until 12 months.
- Teething gets blamed for a lot of night waking, yet a tooth causes discomfort for a day or two rather than weeks, so look at wake windows first.
- Lulla's daily view makes it obvious when the third nap has crept too late, which is the usual reason a 5-month-old fights an otherwise reasonable bedtime.
