Five months old. You've survived the 4-month regression (or you're still crawling out of it), your baby is rolling, laughing, grabbing things with both hands, and suddenly showing a real personality. Sleep feels like it should be getting easier.
And it is. Mostly. Five months is an in-between age. Not quite the chaos of the early months, not yet the predictability that shows up around 6 months. Some days you get three solid naps and a textbook bedtime. Other days, the fourth nap happens in the car because nothing else worked.
How much sleep does a 5-month-old need?
The AASM recommends 12 to 16 hours of total sleep per day for infants 4 to 12 months, including naps.1 The National Sleep Foundation narrows that to 12 to 15.2 Most 5-month-olds land around 14.5 hours: about 10 at night and 4.5 during the day.3
A 2012 systematic review of 34 studies found that normal infant sleep ranged from 9.7 to 15.9 hours.4 Your baby might need 13.5 hours and be perfectly happy. These are population averages, not prescriptions.

Wake windows at 5 months
At 5 months, most babies handle about 1 hour 40 minutes to 2.5 hours of awake time between sleeps. The typical window is around 2 hours and 10 minutes (130 minutes).
The first wake window of the day is the shortest, roughly 80% of the midday window. That means about 1 hour 40 minutes to 1 hour 45 minutes after waking up before the first nap. Sleep consultants consistently recommend this asymmetry because sleep pressure hasn't built up yet after a long night of sleep.5
The last window before bed runs a bit shorter than the midday ones too (about 85% of midday). Stretching that last window too far tips babies into overtiredness, which makes falling asleep harder, not easier.
Our wake windows chart has the numbers for every age.
How many naps at 5 months?
Five months is the messy middle of the 4-to-3 nap transition. Your baby is likely right in the thick of it. That transition typically happens around 4 months, with a full range of 3 to 5 months.6 Some 5-month-olds are already on a solid three-nap schedule. Others still need four naps on short-nap days.
Think of it as 3.5 naps on average. On a good day with longer naps, three will do. On a day full of 30-minute catnaps, you'll need a fourth to bridge the gap to bedtime without your baby falling apart.
Individual naps at this age range from 30 to 60 minutes.3 Short naps (one sleep cycle, about 30 to 40 minutes) are still biologically normal. Some babies are starting to link sleep cycles into longer stretches, but plenty haven't figured that out yet.
Signs the transition to three naps is complete: wake windows are consistently closer to 2 hours, the fourth nap gets refused or takes forever to settle, and your baby seems fine staying awake longer in the afternoon.
Our nap transition guide covers the signs and timing in detail.
A sample day
Exact times depend on your baby's morning wake-up. The structure and spacing matter more than the clock.
3-nap day (most common at 5 months):
| Time | Activity |
|---|---|
| 6:30 AM | Wake up, first feed |
| 7:00 AM | Play, tummy time |
| 8:15 AM | Nap 1 (45 min to 1 hour) |
| 9:15 AM | Wake, feed |
| 9:30 AM | Play, explore |
| 11:30 AM | Nap 2 (45 min to 1 hour) |
| 12:30 PM | Wake, feed |
| 1:00 PM | Play, outdoor time |
| 3:00 PM | Nap 3 (30 to 45 minutes) |
| 3:45 PM | Wake, feed |
| 4:15 PM | Play, family time |
| 6:15 PM | Bedtime routine (bath, pajamas, book, feed) |
| 7:00 PM | Bedtime |
4-nap day (when naps are short):
| Time | Activity |
|---|---|
| 6:30 AM | Wake up, first feed |
| 8:10 AM | Nap 1 (30 min) |
| 8:40 AM | Wake, feed |
| 10:30 AM | Nap 2 (30 min) |
| 11:00 AM | Wake, feed |
| 12:50 PM | Nap 3 (30 min) |
| 1:20 PM | Wake, feed |
| 3:10 PM | Nap 4 (30 min catnap) |
| 3:40 PM | Wake |
| 6:15 PM | Bedtime routine |
| 7:00 PM | Bedtime |
Bedtime at 7 PM for a 5-month-old feels early, but research supports it. A 7 to 8 PM bedtime window aligns with the infant melatonin surge that happens in the early evening.7 Earlier bedtimes are associated with longer nighttime sleep stretches.8
On a bad nap day, don't hesitate to move bedtime earlier. If the last nap was refused or lasted 20 minutes, a 6:30 PM bedtime is better than pushing a cranky baby to 7:30.
Feeding and sleep at 5 months
Most 5-month-olds take 5 to 7 milk feeds (breast or bottle) per day. Some pediatricians give the green light to start introducing solid foods around this age, though many families wait until 6 months, which is the WHO recommendation.910 If you are starting solids early, we're talking about tiny tastes (a few spoonfuls of pureed vegetables or rice cereal), not meals.
For night feeds, many 5-month-olds can go 6 to 8 hours without eating overnight. One to two night feeds is still common and normal at this age.11 If your baby wakes once around 3 or 4 AM, that's a reasonable feed. If they're waking every 2 hours, that's more likely a habit or a sleep association issue than hunger.
Watch out for feeding right before naps. If the baby always falls asleep eating, they start needing that to get to sleep, and then you're stuck. Feed after waking, play in the middle, sleep at the end. That eat-play-sleep rhythm works well at this age.
Our feeding guide has amounts and frequencies by age.
Common problems at this age
The 4-month regression aftermath. The 4-month sleep regression permanently changes your baby's sleep architecture from newborn-style to adult-style NREM/REM cycling.312 The regression itself peaks between 3.5 and 5 months, so some 5-month-olds are still in the thick of it. If sleep fell apart at 4 months and hasn't recovered, the underlying cause is usually that your baby hasn't learned to connect sleep cycles on their own. Our sleep regression guide goes deeper.
Short naps that won't budge. Thirty-minute naps are the defining struggle of this age. The baby wakes after one sleep cycle and can't get back to sleep. Common culprits: wake window too short (the baby isn't tired enough to push into a second cycle), room too bright, or the baby falls asleep with help (rocking, feeding) and can't recreate those conditions when they wake briefly between cycles.
Fighting the last nap. When your baby resists that third or fourth nap, it's tempting to just skip it. Be careful. Dropping a nap too early leads to overtiredness and worse nighttime sleep. If the last nap is a battle, try a shorter wake window before it, a stroller walk, or the car. The goal is just a short bridge nap, not a full sleep.
Early morning wakes. Waking before 6 AM is common at 5 months. Counterintuitively, the most frequent cause is bedtime being too late, not too early. Overtiredness produces cortisol, which fragments sleep in the early morning hours. Other causes: the room getting light too early, or the last nap running too long and pushing bedtime off schedule.
FAQ
Is 5 months too early for a sleep schedule?
No. By 4 to 5 months, babies produce melatonin predictably and have a developing circadian rhythm.7 A schedule at this age is more of a loose framework than a rigid timetable. Follow wake windows and sleepy cues, and use the clock as a backup. Consistency with bedtime (within a 30-minute window) helps the most.
How do I know if my baby is ready for 3 naps instead of 4?
A few things to look for: wake windows stretching past 2 hours consistently, the fourth nap getting refused or pushed very late, and your baby handling the longer afternoon stretch without melting down. If you try 3 naps and bedtime falls apart, go back to 4 for another week or two and try again.
Can a 5-month-old sleep through the night?
Some already do. At 5 months, many babies can physically go 6 to 8 hours without a feed.11 Whether yours does depends on how they fall asleep, feeding patterns, and temperament. One wake-up to eat is still very normal and doesn't mean anything is wrong.
Should I wake my baby from naps?
If a nap is running so long it'll push the next nap or bedtime too late, yes. A reasonable cap at this age is about 2 hours for any single nap, and about 4.5 hours of total daytime sleep. Nighttime sleep (10+ hours) is the priority.
