5-month sleep at a glance

At 5 months, a baby needs roughly 14 to 16 hours of total sleep in 24 hours: about 10.5 to 11.5 hours overnight and 4 to 5 hours spread across daytime naps. Wake windows run about 1.75 to 2.5 hours, and most babies are taking 3 or 4 naps depending on how long the first two naps have stretched. This is a transitional month more than a settled one, the day between month four's scattered naps and month six's more defined 2-to-3 nap rhythm.

Age Total sleep Naps Daytime sleep
3-5 months14-16 hrs3-44-5 hrs

Those figures follow the sleep-duration consensus from the American Academy of Sleep Medicine and stay consistent with our baby sleep schedule by age and wake windows by age references. Treat them as ranges: a baby anywhere inside them who wakes rested is doing fine.

Sample day: 4 naps

Babies whose naps are still on the shorter side, especially the earlier ones, often still need a fourth, later nap to bridge the gap to bedtime without becoming overtired.

Time What's happening Wake window
7:00 a.m.Wake and morning feed
8:45 a.m.Nap 1 (about 45 min-1 hr)~1.75 hrs
10:30 a.m.Nap 2, usually the longest (about 1-1.5 hrs)~2 hrs
1:15 p.m.Nap 3 (about 45 min-1 hr)~2.25 hrs
3:45 p.m.Nap 4, short bridge nap (20-30 min)~2 hrs
6:45 p.m.Bedtime routine, then asleep~2.25 hrs

The fourth nap here is doing one job only: keeping the stretch to bedtime short enough to avoid overtiredness. As the first two naps lengthen over the coming weeks, that job disappears and the day naturally collapses to three naps.

Sample day: 3 naps

Once the first two naps consolidate to roughly an hour or more each, many 5-month-olds drop the fourth nap on their own, sometimes fighting it outright for several days before it disappears for good.

Time What's happening Wake window
7:00 a.m.Wake and morning feed
9:00 a.m.Nap 1 (about 1-1.25 hrs)~2 hrs
12:00 p.m.Nap 2 (about 1-1.25 hrs)~2.25 hrs
3:15 p.m.Nap 3, short (30-45 min)~2.25 hrs
6:45 p.m.Bedtime routine, then asleep~2.5 hrs

This is close to the schedule most 5-month-olds are working toward, and it's essentially a preview of the 3-nap pattern that dominates the 6-month stage. See our 6-month-old sleep schedule for what comes next.

Dreamer tip

If your baby fights one specific nap for three or four days in a row, that's usually the transition announcing itself, not a bad stretch. Dropping that nap a few days early rarely hurts; forcing it for another week rarely helps.

Which schedule fits your baby

The 4-versus-3-nap question at 5 months comes down to how much the first two naps have grown. If naps one and two are still 45 minutes to an hour, a fourth nap protects the day from overtiredness. If they've stretched past an hour each, a third nap usually carries the rest of the day fine, and a fourth nap becomes something your baby actively resists rather than needs.

It's common to float between the two for a couple of weeks: four naps on days the morning naps ran short, three on days they ran long. That's not inconsistency, it's the wake window doing its job. Following your baby's actual nap lengths rather than a fixed count is the most reliable way through this particular month.

Wake windows and timing

At 5 months, wake windows run about 1.75 to 2.5 hours, sitting inside the broader 1.5 to 2.5 hour range for 4 to 6 months as a whole. The first window of the morning tends to be the shortest, since sleep pressure is lowest right after a full night, and the window before bedtime tends to be the longest, so enough pressure builds for a solid night's sleep.

This is also the age where the gap between morning and evening windows starts to matter more. A baby who naps beautifully at 9am on a 2-hour window might fight a 1pm nap on the same 2-hour window, simply because the afternoon window at this age often needs to run a little longer. Our full wake windows by age guide covers this curve in more detail.

Night sleep at 5 months

Night sleep at 5 months is often improving but rarely fully settled. Many babies are stretching toward 10 to 11 hours overnight, sometimes with one feed, sometimes with none, but plenty still wake more than once, whether from hunger, habit, or simply not yet knowing how to fall back asleep without help.

Whether to keep a night feed at this age is an individual decision, best guided by your baby's growth and your pediatrician rather than a fixed month milestone. What helps regardless of feeding is a bedtime where your baby is put down drowsy but awake, so falling asleep independently is already a skill they have when they naturally stir between sleep cycles overnight. Our guide on baby sleep as a learned skill walks through how to build that gradually.

Troubleshooting nap resistance and early waking

Two issues show up most at 5 months: a specific nap being fought every day, and mornings starting earlier than they used to.

Fought naps, especially the third or fourth of the day, are usually the clearest sign the 4-to-3 nap shift is underway rather than a sign something's wrong. If a nap is fought for three or more days running, try dropping it and stretching the surrounding wake windows slightly instead of continuing to push it.

Early morning waking before 6 a.m. at this age is most often the day before catching up with your baby: naps that ran short, a late bedtime, or a last wake window that stretched too long. A slightly earlier bedtime, counterintuitively, is usually the fix rather than a later one. Our guide to early morning wake-ups has the full troubleshooting checklist.

Key takeaways

  • A 5-month-old needs about 14 to 16 hours of total sleep, roughly 10.5 to 11.5 hours overnight plus 4 to 5 hours of daytime sleep.
  • Wake windows run about 1.75 to 2.5 hours, shortest in the morning and longest before bed.
  • Both 3-nap and 4-nap days are normal at 5 months; nap length decides which fits, and many babies float between them for a few weeks.
  • A nap that's fought for three or more days in a row is usually the 4-to-3 nap transition starting, not a bad patch.
  • Follow the wake window rather than a fixed clock or nap count, and rebuild the day off actual wake times when a nap runs short.

Frequently asked questions

How many naps should a 5 month old take?

Most 5-month-olds take 3 to 4 naps a day. Babies whose naps are still short and scattered usually need 4, including a brief late-afternoon bridge nap, while babies whose morning naps have lengthened toward an hour often manage on 3. Both patterns are normal, and most babies drift from 4 naps toward 3 sometime during this month.

What are wake windows for a 5 month old?

At 5 months, wake windows are roughly 1.75 to 2.5 hours. The first window after the morning wake-up is usually the shortest, and each window tends to stretch a little longer through the day, with the window before bedtime typically the longest. This sits inside the broader 1.5 to 2.5 hour range for 4 to 6 months.

How much total sleep does a 5 month old need?

A 5-month-old needs about 14 to 16 hours of total sleep in 24 hours, typically made up of roughly 10.5 to 11.5 hours overnight and 4 to 5 hours of daytime sleep spread across 3 to 4 naps. Totals vary from baby to baby, so use the range as a guide and judge whether it's enough by how rested your baby seems during the day.

What time should a 5 month old go to bed?

A bedtime between about 6:30 and 7:30 p.m. suits most 5-month-olds, set by the end of the last nap rather than the clock. Aim to start the bedtime routine after a final wake window of roughly 2 to 2.5 hours from the end of the last nap, which for most babies at this age lands bedtime in that early-evening window.

Is it normal for a 5 month old to still wake at night?

Yes. Many 5-month-olds still wake once or twice overnight for a feed, a resettle, or simply because they haven't yet learned to fall back asleep independently between sleep cycles. Some babies this age do sleep long stretches, but frequent waking is still well within the normal range and isn't a sign anything is wrong.

Why does my 5 month old fight the third or fourth nap?

Fighting a later nap at 5 months is usually the clearest early sign that the day is shifting from 4 naps toward 3. As the first two naps lengthen, there's less sleep pressure left over for a short, late nap, so it becomes harder to get your baby down for it even though the day still has time left before bedtime.
