How Much Should A Baby Sleep? | Hours By Age And Naps

New parents want clear numbers they can use tonight. If you’re asking “how much should a baby sleep?”, you’re in the right place. This guide gives practical ranges, sample plans, and quick fixes from pediatric sleep research.

How Much Should A Baby Sleep? By Age And Naps

Sleep needs shift fast in the first two years. The ranges below reflect a full 24-hour day, including naps. Think in totals first, then shape night sleep to hit that range.

Age	24-Hour Total	Notes
0–3 months	14–17 hours	Short stretches; frequent feeds; day/night not set
4–6 months	12–16 hours	Night lengthens; 3–4 naps common
7–9 months	12–16 hours	2–3 naps; longer wake windows
10–12 months	12–16 hours	2 naps for most; night around 10–12 hours
12–15 months	11–14 hours	Shift toward 1 midday nap begins for some
16–18 months	11–14 hours	One solid nap; steady bedtime helps
19–24 months	11–14 hours	One nap; night consolidates
2–3 years	10–13 hours	Some drop naps near 3 years

Ranges aren’t a test. Some babies sit near the low end and thrive. Others need the high end. Track your child’s mood, feeding, and growth. If the day runs well, the schedule works.

How Much A Baby Should Sleep Per Day, By Age

This close look turns ranges into practical targets. The numbers match expert groups and are easy to map to real days.

Newborns: 0–3 Months

Totals land near 14–17 hours across the day. Stretches may last 1–3 hours. Night sleep builds slowly. A steady light-dark cycle, full feeds, and safe swaddling with hips free can help longer stretches.

Young Infants: 4–6 Months

Most land near 12–16 hours. Nights grow to 9–11 hours broken by brief wakes. Naps drop toward three. A simple routine helps: feed, short play, then sleep when early cues show.

Older Infants: 7–9 Months

Expect two to three naps and 12–16 total hours. Wake windows widen. Many babies manage a 2-3-3 pattern across the day with bedtime set by the last nap end.

Late Infancy: 10–12 Months

Nights often reach 10–12 hours with two naps. Standing practice and new skills can disrupt sleep for a few days. Keep bedtime steady and offer comfort with brief check-ins.

Early Toddlers: 12–18 Months

Totals shift to 11–14 hours. A one-nap schedule starts to make sense for some near 15 months. If a second nap blocks bedtime or causes long split nights, test a single midday nap.

Toddlers: 18–24 Months

Most settle at one nap near mid-day and 11–14 total hours. Teething and travel can add wakes. Keep the routine and reset bedtime earlier for a few days to protect totals.

Two To Three Years

Many still nap; others phase it out. Aim for 10–13 total hours. If naps fade, move bedtime earlier to keep the 24-hour total in range.

What “Good Sleep” Looks Like In Practice

Night Sleep Versus Naps

Totals matter more than perfect splits. A baby who hits the daily range and wakes content is doing well. Tweak the mix only if nights run short, naps fight you, or mornings start too early.

Wake Windows And Cues

Wake windows are the gaps between sleeps when a baby is awake. They get longer with age. Yawns, staring, and hand-to-ear rubbing are classic cues. When you see them, start the wind-down.

Wind-Down Flow That Works

Keep routines simple, calm.

• Dim lights and lower noise.
• Clean diaper and cozy sleep sack.
• Feed if due, then burp upright.
• Lay down drowsy but awake when possible.

You can sanity-check your plan against expert guidance. The AASM pediatric sleep duration consensus outlines age-based ranges based on a large review. For safe sleep setup, the AAP safe sleep guidance covers back-sleeping, a flat surface, and a clear crib.

Sample Day Plans You Can Adapt

Here are simple outlines you can bend to your home, feeds, and childcare. Use them as a start point, not a rigid rule.

5–6 Months: Three-Nap Pattern

• 7:00 a.m. wake, feed, play
• 9:00 a.m. nap 1 (45–90 min)
• 12:30 p.m. nap 2 (60–90 min)
• 4:00 p.m. nap 3 (30–45 min cap)
• 6:45 p.m. bedtime routine
• 7:15 p.m. lights out

8–10 Months: Two-Nap Day

• 7:00 a.m. wake
• 9:30 a.m. nap 1 (60–90 min)
• 2:00 p.m. nap 2 (60–90 min)
• 7:00 p.m. bedtime

12–18 Months: One-Nap Shift

• 6:45 a.m. wake
• 12:15 p.m. nap (90–120 min)
• 6:45–7:15 p.m. bedtime window

How Much Should A Baby Sleep? Sample Day Schedules

You’ll see the question, “how much should a baby sleep?” all over parent chats. This section turns that same phrase into usable plans with times and nap caps.

Wake windows stretch through the first years. Use this table to plan feeds and outings without landing in overtired tears.

Age	Typical Wake Window	Common Naps
0–8 weeks	45–90 minutes	4–6+ short naps
2–3 months	60–120 minutes	4–5 naps
4–5 months	1.5–2.5 hours	3–4 naps
6–7 months	2–3 hours	3→2 naps
8–10 months	2.5–3.5 hours	2 naps
11–15 months	3–4.5 hours	2→1 nap
16–24 months	4.5–6 hours	1 nap
2–3 years	6–7 hours (no-nap days)	0–1 nap

Fixes For Common Sleep Problems

Short Naps

Many babies link one sleep cycle, then wake at 30–45 minutes. Try a darker room, steady white noise, and a longer wake window. Cap late naps so bedtime stays solid.

Split Nights

A long awake period in the middle of the night points to too much day sleep or a bedtime set too early. Trim the last nap, add light morning play, and keep nights calm and boring.

Early Morning Wakes

Check room light first; dawn can cue a wake. Next, look at the first wake window the day before. A long afternoon gap can backfire and pull wake-ups earlier.

Bedtime Battles

Bring bedtime forward for a week. Keep the routine the same every night. Offer a send-off phrase and one last check after a few minutes if needed.

Nap Transitions: Signs And Timing

Moves from four naps to three, then three to two, and two to one follow wake windows and totals. Watch behavior, not the calendar. If naps run long yet nights shrink, a drop may be near. If the last nap blocks bedtime, trim it or test a shift.

From Three Naps To Two

Common near 6–7 months. Signs include a skipped third nap, long singing in the crib at bedtime, or a very early wake the next day. Try lengthening the first two wake windows and cap the second nap so bedtime holds.

From Two Naps To One

Common near 13–18 months. Signs include daily protest at the second nap, short second naps that push bedtime late, and rising night wakes. Slide the first nap later by 15 minutes every few days. Offer an early bedtime during the shift.

From One Nap To Quiet Time

Common near 2.5–3 years. Many stop napping yet still need downtime. Keep a daily quiet hour with books, puzzles, or soft music. On days without a nap, move bedtime earlier to protect the 24-hour total.

Feeding And Sleep: What Really Works

Full feeds help longer stretches. For young infants, try to separate feed and sleep by a short play window once or twice a day. That builds flexible settling skills. Hungry babies wake. Overfull tummies can wake too, so burp well and leave a small gap before laying down.

Night feeds taper with age. Many babies still take one feed near 6 months, then drop it as solids rise. Growth spurts can add a feed for a few nights. Return to your normal routine once the spurt passes.

Travel, Illness, And Time Change

Life happens. When sleep goes sideways, protect the total hours first, then rebuild the structure.

Travel

Keep the bedtime routine even in a hotel room. Use the same song and phrases. Bring a portable blackout shade and a small sound machine. On return, reset the home schedule within two to three days.

Illness

Comfort takes priority. Expect extra contact naps and a later bedtime. Once energy returns, nudge wake windows back to baseline and wean any added night feeds with short, steady changes.

Time Change

Shift the schedule by 10–15 minutes per day for a week. Morning light helps anchor the new clock. Keep naps on the new time even if the first day feels off.

Room Setup And Routine Checklist

Small tweaks add up. Use this quick scan to boost sleep quality without turning your home upside down.

• Room light: keep dark for sleep and bright for wake.
• Noise: steady sound masks doorbells and street noise.
• Temperature: a cool room near 20–22°C with a breathable sleep sack.
• Crib setup: flat, firm mattress; fitted sheet only.
• Day rhythm: fresh air, floor play, and regular mealtimes.
• Bedtime routine: same steps, same order, calm tone.

Safe Sleep Basics You Should Know

Back sleep, firm flat surface, and a clear crib with no loose items reduce risk. Room-share without bed-sharing in the early months. Swaddles come off once rolling starts. A well-fitted sleep sack works long term. Keep the room smoke-free and avoid inclined seats for sleep.

When To Talk To The Pediatrician

Reach out if totals sit far below the ranges, if loud snoring or long pauses in breathing show up, or if feeds stall. Share a two-week sleep log and any monitor data. Timely care helps everyone rest better.

Parents ask “how much should a baby sleep?” to build steady days and restful nights. Use the ranges, watch cues, and shape a plan that fits your home.
