Baby Sleep Schedules by Age: 3 to 12 Months

Sleep needs shift steadily across this stretch — naps consolidate, wake windows stretch, and bedtime moves later — and almost all of it is normal, expected change rather than something to fix.

Safe sleep reminder: Always place baby on their back to sleep, on a firm, flat sleep surface in their own crib, bassinet, or play yard, with a fitted sheet only and no loose blankets, pillows, bumpers, stuffed animals, or other soft items.

The big picture

Between 3 and 12 months, a baby’s sleep goes through more change than at almost any other stage. Naps shrink from five a day down to two, wake windows roughly triple, and bedtime drifts from mid-evening toward a steadier 7:00–8:00 PM. None of these shifts happen on a fixed calendar date — every baby moves through them on their own timeline, often with a few uneven weeks in between. Below is a month-by-month reference, followed by what’s actually driving the changes at each stage.

Quick-reference table

Age	Total sleep (24 hrs)	Naps	Typical wake window	Typical bedtime
3 months	~15 hrs (10+ night, 4-5 day)	4-5	1-2 hrs	12-14 hrs after wake, not before 6:00 PM
4 months	~14.5 hrs (11-12 night, 3.5-4.5 day)	3-4	1.5-2.5 hrs	6:00-8:00 PM
5 months	~14.5 hrs (11-12 night, 2.5-3.5 day)	3-4 (shifting to 3)	2-2.5 hrs (up to 3 near 6mo)	6:00-8:00 PM
6 months	~14 hrs (11-12 night, 2.5-3.5 day)	3	2-3 hrs	7:00-8:00 PM
7 months	~14 hrs (11-12 night, 2.5-3 day)	2-3	2.25-3.5 hrs	7:00-8:00 PM
8 months	~14 hrs (11-12 night, 2-3 day)	2-3 (shifting to 2)	2.25-3.5 hrs	12-14 hrs after wake, not before 6:00 PM
9 months	~14 hrs (11-12 night, 2-3 day)	2	2.75-3.5 hrs	12-13 hrs after wake, not before 6:00 PM
10 months	~13.5 hrs (11-12 night, 2-3 day)	2	3-3.75 hrs	12-13 hrs after wake
11 months	~13.5 hrs (11-12 night, 2-3 day)	2	3-3.75 hrs	12-13 hrs after wake, not before 6:00 PM
12 months	~13.25+ hrs (11-12 night, 2-3 day)	2	3.25-4 hrs	12-13 hrs after wake

These are averages, not strict targets — there is a wide range of normal at every age. A baby’s mood, energy, and ease of settling tell you as much about whether they’re getting enough rest as the clock does.

3-4 months: rhythm forming, and the “4-month regression”

At 3 months, sleep is still fairly scattered — 3-5 naps a day, ranging from 30-45 minute catnaps to longer 1-2 hour stretches, with a nap usually needed after just 60-120 minutes of awake time. Night waking to feed is still expected. Around 3-4 months, an important shift happens internally: a baby’s circadian rhythm matures and their sleep cycling changes, adding more of the lighter and deeper sleep stages that adults cycle through. This is often called the “4-month sleep regression” — but it’s better understood as forward progress. It commonly shows up as more frequent night waking and shorter naps for a few weeks, and it reflects healthy development, not something going wrong.

By 4 months, most babies are sleeping closer to 14.5 total hours, spread across 3-4 naps with individual naps generally capped around 2 hours. Enough melatonin is typically being produced by now to support a more regular 24-hour rhythm, and bedtime tends to settle into a 6:00-8:00 PM window.

This is also the age most families transition away from swaddling — both because babies begin working on rolling from roughly 4 to 7 months, and because free hands support a baby’s own ability to self-soothe. Swaddling is no longer safe once a baby shows any sign of rolling, even an attempt. Switching to a sleep sack or an arms-free transitional swaddle at that point keeps sleep safe while still offering a snug, secure feeling.

Gentle groundwork for independent sleep — brief pauses before responding, or approaches like gradual withdrawal — can reasonably begin around 3-4 months, though most babies aren’t developmentally ready to reliably link sleep cycles through the night until closer to 6 months.

5-6 months: the first nap consolidation

Around 5 months, the first two naps of the day typically start to lengthen to roughly 1-1.5 hours, which is usually the signal that a baby is ready to move from 4 naps down to 3. A 3-nap schedule generally requires a baby to comfortably stay awake 2-3 hours between sleeps. This is also the stretch when rolling becomes common in both directions — most babies can roll stomach-to-back first, with both-direction rolling typical by around 6 months. If a baby rolls onto their stomach after being placed on their back, it’s fine to give them a few minutes to see if they roll back on their own before stepping in.

By 6 months, most babies have settled into a clear 3-nap rhythm: the first two naps around 60-90 minutes each, and a shorter third nap of about 30-45 minutes to bridge to bedtime. Bedtime is usually 12-13 hours after the morning wake-up, commonly landing around 7:00-8:00 PM. It’s worth resisting the urge to drop a nap early here — most babies aren’t ready for a 2-nap schedule until 7-9 months, and dropping down too soon tends to increase night waking rather than improve it.

Six months is also a common point where families start working on independent falling-asleep skills, since most babies are developmentally capable of it by now. If a baby is still routinely rocked or fed all the way to sleep and the household isn’t getting enough rest, this is a reasonable and common time to begin.

7-9 months: the 3-to-2 nap transition

Wake windows keep stretching through this stage — typically 2.25-3.5 hours at 7 months, extending toward 2.75-3.5 hours by 9 months. Nap resistance, especially at the third nap, becomes common as babies simply need longer stretches of wakefulness than a 3-nap schedule allows, but aren’t quite ready to fully drop to 2 naps until somewhere in the 7-9 month range.

A few things help stabilize sleep through this transition:

Anchoring the first nap of the day at a consistent time helps regulate the whole day’s rhythm.
A dark room supports longer naps and helps a baby link sleep cycles instead of waking fully at every light cue.
Once the third nap is dropped, an earlier bedtime — plus a longer, calmer wind-down routine — helps offset the extra tiredness that a missing nap leaves behind.
The shift from 3 naps to 2 can take a few weeks, with a mix of 3-nap and 2-nap days along the way. That back-and-forth is expected, not a sign anything is wrong.

Around 8 months is also a reasonable point to start shifting from a purely wake-window-based schedule toward a consistent by-the-clock routine — offering naps and bedtime at roughly the same times each day, even with small variation in the morning wake-up. Bedtime in this window is typically 2.75-3.5 hours after the last nap ends, and 12-14 hours after the morning wake time, but not earlier than 6:00 PM.

By 8 months, most babies are active rollers, and swaddling is no longer appropriate at any point — both for rolling safety and because it can get in the way of a baby’s own settling skills. Some 7-9 month-olds sleep through the night without any feeds; others still do well with one, whether a dream feed close to the parents’ own bedtime or a feed in the early morning hours (roughly 3:00-5:00 AM).

10-12 months: settling into 2 naps

By 10 months, most babies have settled firmly into a 2-nap schedule, with wake windows extending to about 3-3.75 hours. This is a good time to lean fully into a predictable, clock-based routine rather than one driven purely by watching for tired cues. Bedtime typically falls 12-13 hours after the morning wake-up, aiming for 11-12 hours of night sleep; if daytime naps run especially long, night sleep may come in a bit shorter but should still average at least 10 hours.

At 11 months, most babies still need 2 naps at least some of the time — commonly until around 14 months — so nap resistance at this age doesn’t necessarily signal readiness for 1 nap. If a nap does get skipped, an earlier bedtime helps, but it’s best kept no earlier than 6:00 PM, since an overly early bedtime tends to cause very early morning waking instead of solving it.

At the 12-month mark, a full 1-nap schedule is typically still too early. A true 1-nap routine often requires staying awake 5+ hours at a stretch, which is more than most 1-year-olds can manage without building up more tiredness than is ideal. Some daycare settings move children to 1 nap right at 12 months regardless of readiness — if that’s the case, keeping 2 naps on non-daycare days and setting an earlier bedtime on the 1-nap days can ease the adjustment. Total sleep at 12 months is generally at least 13.25 hours, split between 11-12 hours at night and 2-3 hours across those 2 daytime naps, with wake windows around 3.25-4 hours.

By 10-11 months, many babies can sleep through the night without eating at all, though some still benefit from one early-morning feed. Adding more calorie-dense food during the day, and paying attention to dinner timing, can help address hunger-driven early waking. By 12 months, night feeding is typically not developmentally necessary for most babies, and the same daytime-calorie strategy applies if early waking continues.

Safe sleep through the first year

A few safe-sleep points carry through this entire age range and are worth keeping front of mind as your baby grows and moves more:

Back sleep is the recommendation for every sleep, at every age, through 12 months. Once a baby can roll both directions on their own — back-to-front and front-to-back — it’s fine to let them settle into whatever position they land in, as long as the rest of the sleep space stays clear and safe.
A pacifier during sleep is fine, and may even help lower SIDS risk — just don’t let it substitute for or delay a feeding.
Swaddles are only safe before rolling begins. The moment a baby shows any rolling attempt, it’s time to switch to a sleep sack or an arms-free transitional swaddle.
Around the first birthday, it’s reasonable to ask your pediatrician whether it’s an appropriate time to introduce a pillow or a lovey into the sleep space — this is an individual call best made with your baby’s own doctor.

A word on “regressions” and rough stretches

Sleep regressions aren’t tied to one universal date that applies to every baby. Rough patches can crop up at various points across this age range and often line up with a developmental leap, teething, a stretch of illness, or simply a schedule that’s fallen a step behind what your baby’s body now needs. Most of these resolve on their own once the schedule catches up to your baby’s age and a consistent routine is back in place. Across every stage in this range, the most common driver of extra night waking and early morning waking is simply too much daytime wakefulness for the age — building an earlier bedtime back in is usually the most effective first step.

A steady bedtime and nap routine — a bath, a book, a few minutes of quiet connection before lights-out — is consistently linked with better sleep for babies at every age in this range, and it’s one of the simplest levers a family has to work with.
