5 Month Old Sleep Schedule: Naps, Wake Windows & Sample Day

Finding a 5 month old sleep schedule that actually works can feel like a moving target: many babies are still recovering from the 4 month regression, naps are just starting to organize, and wake windows are stretching week by week. Here’s a realistic hour-by-hour sample, how many naps to expect, wake windows, and how much a baby this age sleeps on average — with a gentle, evidence-based approach.

How much does a 5 month old sleep?

On average, a 5 month old sleeps around 14–15 hours per 24 hours: about 11 hours at night (often still with 1 or 2 feeds) and roughly 3–4 hours during the day split across naps. These are rough averages — not a prescription. There are perfectly healthy babies who sleep a little more or a little less. What matters isn’t hitting an exact number, but that your baby wakes reasonably rested and doesn’t build up overtiredness across the day.

Wake windows at 5 months

The wake window is how long your baby can stay awake and content between sleeps. At 5 months it’s usually between 2 and 2.5 hours, with two nuances that shape the whole day:

• The first window of the morning is the shortest (often ~2 hours).
• The last window before bedtime is the longest (it can reach 2.5–3 hours).

Use age as a starting point and sleepy cues as your real guide: a glazed stare, rubbing eyes or ears, yawning, slowing down, or getting fussy. Start the wind-down at the first cues, before the meltdown — overtiredness is the single biggest cause of short naps and rough nights at this age.

Age	Wake window	Naps/day	Total sleep ~24h
3–4 months	1.25–2 h	3–4	~14–15 h
5 months	2–2.5 h	3–4 (→ 3)	~14–15 h
6 months	2–2.5 h	3 (→ 2)	~14 h

How many naps does a 5 month old take

Most 5 month olds take 3 to 4 naps. Many are transitioning down from four shorter, less predictable naps to three more organized ones. Typically that means two longer naps in the morning and midday, plus a short catnap in the late afternoon to bridge the gap to bedtime without overtiredness.

Signs the day is starting to settle into 3 naps:

• Two of the naps are getting longer and more consistent.
• The last short catnap is easy to drop on days when the earlier naps were solid.
• Bedtime lands at a similar time each night.

There’s no rush and no fixed date. At 5 months, keeping a flexible short fourth nap is completely normal, especially after a day of short sleep. The transition happens gradually as wake windows stretch.

5 month old sleep schedule: hour-by-hour sample (3–4 naps)

Here’s a realistic sample for a baby who wakes around 7:00. Adjust it to whenever yours wakes up — what matters are the windows, not the exact clock.

Time	What’s happening	Prior window
7:00	Wake + feed	—
9:00	Nap 1 (~1–1.5 h)	~2 h
11:45	Nap 2 (~1–1.5 h)	~2 h 15
14:30	Nap 3 (~45 min–1 h)	~2 h 15
17:00	Optional short catnap (~20–30 min)	~2 h
19:15	Routine + bedtime	~2 h 15

Notes to make it actually work:

• Drop the optional catnap on days when the earlier naps were long — this is the nap you’re gradually letting go of.
• If a nap comes out very short, shorten the next window a little to make up for the extra tiredness.
• Don’t let the last nap end too late: a late catnap pushes bedtime back and can throw the whole night off.
• Feeding still sets the rhythm at 5 months: breast milk or formula remains the main source of nutrition. Talk to your pediatrician about whether and when to start solids — the AAP suggests around 6 months.

What helps the schedule click into place

1. Wake windows by age, not a rigid clock

Overtiredness is the number-one amplifier of sleep problems: too much awake time floods the body with cortisol and makes settling harder. Lean on wake windows and your baby’s cues rather than a fixed time. Our guide to wake windows by age breaks this down stage by stage.

2. A short, predictable bedtime routine

A brief, repeatable wind-down is one of the best sleep tools there is. The NHS recommends a consistent routine — for example dim lights, a bath, a feed, and a quiet song — to signal to the body that sleep is coming. Keep the last 20–30 minutes screen-free.

3. Chances to fall asleep drowsy-but-awake

If your baby only falls asleep nursing or in your arms, they may need that same help when they wake between cycles at night. Giving them the chance to settle at the start of the night, put down drowsy but awake, helps them link cycles. It’s gradual and gentle — it is not leaving them to cry.

4. A sleep environment that supports rest

A dark room, steady white noise, and a comfortable temperature (often 68–72 °F / 20–22 °C) make it easier to fall asleep and resettle, especially during the lighter sleep phases that are so common at this age.

5. Safe sleep, always first

Many babies start rolling around 4–6 months, so safe sleep matters more than ever. The American Academy of Pediatrics (AAP) recommends placing your baby on their back for every sleep, on a firm, flat surface, with no loose bedding, pillows, soft toys, or bumpers, and room-sharing without bed-sharing. Crucially, stop swaddling as soon as you see the first signs of rolling — a swaddled baby who rolls to their tummy can’t push up safely. Switch to a sleep sack with arms free.

When the schedule “doesn’t fit” (and what to check)

If you’ve been trying a schedule for days and sleep is still broken, it’s usually one of these causes, not because the sample is wrong:

• Windows too long → overtiredness → short naps and night wakings.
• Windows too short → your baby doesn’t have enough “sleep pressure” and resists.
• A very late last nap → bedtime shifts and the night gets choppy.
• Lingering effects of the 4 month regression → the new, more adult-like sleep pattern is still bedding in.

If nights have been especially rough, the 4 month sleep regression guide explains the shift your baby is still settling into, and if you want the bigger picture, why won’t my baby sleep walks through the most common causes step by step.

When to check with your pediatrician

Sleep ups and downs at this age are usually normal. But check in with your pediatrician if you notice persistent snoring or breathing pauses during sleep, poor weight gain or feeding difficulties, extreme daytime sleepiness, or anything that simply worries you. A sleep schedule is a support tool — it never replaces a clinical check.

The bottom line

At 5 months, a good schedule rests on three pillars: wake windows of 2–2.5 hours, 3 to 4 naps (with the settle into 3 on the horizon), and a steady bedtime routine, all on a foundation of safe sleep. Start with the sample above, adjust it to whenever your baby wakes, and let their cues fine-tune the rest. Consistency, more than perfection, is what settles the nights.
