Baby Sleep Schedule by Age: Newborn to 12 Months

Sleep is the most talked-about topic in early parenting — and the most misunderstood. The question isn't just "how do I get my baby to sleep?" It's what should sleep actually look like right now, for this age?

The answer changes dramatically across the first year. A 2-week-old and a 10-month-old have almost nothing in common when it comes to sleep. Wake windows, nap counts, total sleep hours, nighttime expectations — all of it shifts every few months.

This guide covers what sleep actually looks like at each age, with sample daily schedules, common regressions, safe sleep basics, and realistic expectations. No sleep-shaming. No rigid schedules that ignore your real life. Just the information that helps.

How to Use This Guide

Look up your baby's current age range. Find the total sleep hours, wake windows, and nap expectations for that stage. Use the sample schedule as a rough framework, not a strict prescription. Babies are not robots — but most fall within these windows when they're fed, healthy, and have consistent sleep conditions.

If your baby seems to need significantly more or less than these ranges, mention it to your pediatrician at the next visit.

Newborn (0–4 Weeks): Survival Mode

Total sleep: 14–17 hours per 24 hours

Wake windows: 45–60 minutes

Naps: 4–8 short naps (no schedule yet)

Nighttime: Feeds every 2–3 hours; no sleeping through the night

At this stage there is no "schedule." Newborns cycle between sleeping and eating around the clock. Their circadian rhythm (the biological clock that distinguishes day from night) hasn't developed yet. This isn't fixable by routine — it resolves on its own around 6–8 weeks as melatonin production matures.

1–2 Months: Small Patterns Begin

Total sleep: 14–17 hours per 24 hours

Wake windows: 60–90 minutes

Naps: 4–6 naps

Nighttime: 1 longer stretch (3–5 hours) may emerge, but still multiple night feeds

Around 6–8 weeks, most babies begin showing a longer sleep stretch — often 3–5 hours — in the early part of the night. This is the first glimpse of consolidation. Don't try to engineer it; let it emerge.

You can start introducing a loose bedtime routine at 6–8 weeks: consistent order, dim light, low stimulation. It doesn't need to happen at the same clock time yet. The signal is the routine, not the hour.

Sample schedule (very loose):

3–4 Months: The Regression Hits

Total sleep: 14–16 hours per 24 hours

Wake windows: 1.5–2 hours

Naps: 3–4 naps

Nighttime: Was improving — now often feels like it's going backward

The 4-month sleep regression is real. It's not a phase that passes — it's a permanent neurological change. Around 3.5–4 months, babies transition from newborn-style sleep cycles to adult-style cycles (light sleep → deep sleep → light sleep → repeat). This means they now partially wake between each cycle, which they didn't do before.

Before this change, babies could fall asleep any way and stay asleep. After it, they need to put themselves back to sleep at each cycle transition. If they were nursed or rocked to sleep, they'll look for those same conditions when they surface.

This is why the "4-month regression" often feels worse than everything before it — and why it can last weeks or months if the underlying sleep associations aren't addressed.

What helps:

5–6 Months: Consolidation Window

Total sleep: 13–15 hours per 24 hours

Wake windows: 2–2.5 hours

Naps: 3 naps (moving toward 2)

Nighttime: Capable of 5–8 hour stretches; many still wake 1–2 times

At 5–6 months, babies are neurologically ready to sleep longer stretches. Whether they do depends heavily on sleep associations and whether they've learned to fall asleep independently. A 5-month-old who falls asleep nursing will usually still wake every sleep cycle looking to nurse again.

If you want to reduce night waking, this is an optimal window. Most major sleep training approaches (Ferber, Weissbluth, Sleep Lady Shuffle, pick-up/put-down) work well here.

Many babies are transitioning from 3 naps to 2 sometime between 5–7 months. Signs the third nap is no longer needed: it becomes hard to settle, bedtime is delayed, or nap 1 and 2 are getting longer.

Sample schedule (5–6 months):

7–9 Months: Settling Into 2 Naps

Total sleep: 12–15 hours per 24 hours

Wake windows: 2.5–3.5 hours

Naps: 2 naps (1.5–2 hours each, ideally)

Nighttime: Biologically capable of sleeping 10–12 hours; many still wake

Most babies complete the 3-to-2 nap transition by 7–8 months. Once on 2 naps, the schedule becomes more predictable — a morning nap roughly 2.5–3 hours after waking, and an afternoon nap roughly 2.5–3 hours after that.

The 8-month sleep regression is common, often triggered by a developmental leap (pulling to stand, increased mobility) or by separation anxiety, which peaks around 8–9 months. It typically passes in 2–3 weeks without changes to the schedule.

Sample schedule (7–9 months):

10–12 Months: Approaching Toddler Sleep

Total sleep: 12–14 hours per 24 hours

Wake windows: 3–4 hours

Naps: 2 naps (some early 1-nap transitions around 11–12 months)

Nighttime: 10–12 hours; 0 feeds typical for most babies

By 10–12 months, most babies are on a predictable 2-nap schedule and sleeping a consolidated stretch at night. If night waking is still frequent at this age, it's almost always habitual (not nutritional or developmental) and can be addressed with sleep training if desired.

The 1-nap transition usually happens between 14–18 months — earlier than many parents expect, but some babies begin showing signs around 12 months (fighting the morning nap, short afternoon nap, late bedtime).

Sample schedule (10–12 months):

Sleep Regressions: A Quick Reference

| Age | What's Happening | Duration |

|-----|-----------------|----------|

| 3–4 months | Permanent shift to adult-style sleep cycles | 2–6 weeks |

| 6 months | Developmental burst (rolling, sitting) | 1–3 weeks |

| 8–10 months | Mobility + separation anxiety | 2–4 weeks |

| 12 months | Transition anxiety, 1-nap shift beginning | 1–3 weeks |

The best response to any regression: keep the schedule consistent, temporarily increase reassurance if needed, and wait. They resolve.

Safe Sleep: The Non-Negotiables

Back to sleep, every sleep. The back-sleeping position for every nap and every night dramatically reduces the risk of SIDS. Once a baby can roll both ways independently, rolling onto their stomach during sleep is fine — but always place them on their back.

Firm, flat sleep surface. A firm crib or bassinet mattress with a fitted sheet. No soft bedding, bumpers, pillows, or positioners in the sleep space.

Own sleep space. Room-sharing (in the same room, not the same bed) is recommended by the AAP for at least the first 6 months. Bed-sharing increases the risk of infant suffocation — this risk is highest with soft mattresses, alcohol, sedating medications, or extreme parental fatigue.

Temperature. Sleep environment should be 68–72°F. A sleep sack (wearable blanket) is safer than a loose blanket once baby is out of a swaddle.

Swaddle until rolling. Stop swaddling as soon as baby shows signs of rolling over. A swaddled baby who rolls to their stomach cannot push back up.

When to Talk to Your Pediatrician

Most sleep variation in the first year is normal. A few patterns worth mentioning:

What Actually Matters

Schedules are a tool, not a standard to judge against. The goal is a baby who is well-rested and a parent who is as functional as possible.

Some babies nail age-appropriate sleep with minimal effort. Others need more support, more consistency, or more time. Neither category says anything about your parenting.

The variables you control: consistent sleep conditions, appropriate wake windows, a calming routine, and a safe sleep space. The variables you don't control: your baby's individual temperament, developmental timing, and the random chaos of infancy.

Work the variables you have. Let go of the rest.
