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

New parents ask this on day one: how much should my baby sleep? Babies sleep a lot, but the pattern changes fast. This guide gives clear numbers by age, shows how naps evolve, and offers simple tweaks that help nights go smoother.

How Much Should My Baby Sleep? By Age Chart

The table below summarizes typical 24-hour totals and a night/day split. Individual babies vary, and short phases off pattern are normal during growth spurts or illness.

Age	Total In 24 Hours	Night / Day Split
Newborn (0–3 months)	14–17 hours	6–9 night / 8–9 naps, in short stretches
4–6 months	12–16 hours	8–11 night / 4–6 naps
7–9 months	12–15 hours	9–11 night / 3–4 naps
10–12 months	12–15 hours	10–11 night / 2–4 naps
13–18 months	11–14 hours	10–11 night / 1–3 naps
Toddler (1–2 years)	11–14 hours	10–11 night / 1–2 naps
Preschool (3–5 years)	10–13 hours	10–12 night / 0–1 nap
School Age (6–12 years)	9–12 hours	All at night

Baby Sleep Hours By Age (Newborn To 18 Months)

Here’s what the day often looks like across the first year and a half, plus quick steps that tend to help at each stage.

Newborns (0–3 Months)

Newborn sleep comes in short bursts around the clock. Expect many night feeds, frequent naps, and wide swings from day to day. Light exposure and gentle daytime play help the body clock emerge. Place your baby on the back for every sleep on a firm, flat surface with no soft bedding.

4–6 Months

Circadian rhythm takes hold. Many babies link the first stretches of night sleep, then wake for feeds. A short, calm routine plus a consistent bedtime window improves overnight length. If you wonder “how much should my baby sleep?”, this age band lands near 12–16 hours over 24 hours including naps.

7–9 Months

Most babies move to 3–4 hours of daytime naps split across two or three naps. Mobility gains can stir up night waking for a few weeks. Keep bedtime steady and make daytime practice of new skills part of the routine to reduce overnight practice.

10–12 Months

Many shift to two naps and consolidate a longer first stretch at night. Teething and separation awareness can add brief protests. A short check-in and a predictable wind-down often shorten these bumps.

13–18 Months

Most toddlers settle into one midday nap by 15–18 months. Total sleep drops a bit, yet night stretches improve with a stable schedule and lots of daylight play.

What The Guidelines Say About Baby Sleep

Leading groups publish ranges rather than a single “right” number. You can read the CDC sleep chart for age-by-age targets, which align with the American Academy of Sleep Medicine consensus. If your baby sits near the edges of a range but is feeding well and growing, that can still be normal.

Nap Basics: Length, Timing, And Transitions

Nap Length

Short naps are common early on. A 30–45 minute catnap may be all a young baby can link. By 6–9 months, many naps stretch to 60–90 minutes.

Nap Timing

For the first months, follow sleepy cues: red brows, zoning out, slow blinking. Later, watch wake windows: short in the morning, longer by late afternoon. Many babies nap best with a morning nap starting 2–3 hours after wake-up.

Dropping Naps

When naps run long and bedtime slips late, or your baby plays through a nap and stays cheerful, it may be time to trim or drop one. Shift bedtime a bit earlier for a week while the body adjusts.

Signals Your Baby Needs More Or Less Sleep

Needs More

• Hard wake-ups even after a calm night
• Frequent late-day meltdowns
• Short naps with cranky wake-ups

Needs Less

• Long periods of quiet play in the crib before sleep
• Early morning wide-awake energy for days in a row
• Bedtime fights disappear after a small nap trim

Safe Sleep Setup That Also Helps Sleep

Safety comes first and supports better rest. Always use the back-to-sleep position, a firm flat mattress, and a clear crib. Share a room without sharing a bed for at least the first 6 months. Review the AAP policy on reducing infant sleep-related deaths if you need a quick checklist.

Schedules, Routines, And Flexibility

A simple routine sets the cue: feed, clean diaper, dim lights, one short book or song, then down on the back while drowsy. Keep the steps the same even if timing slides a bit. Daylight, outside time, and a predictable first nap anchor the day. When travel or illness knocks things off track, keep the order and trim expectations for a week.

Common Sleep Challenges And Fixes

Day/Night Mix-Ups

Give morning sunlight, lively play by day, and dim, quiet nights. Pause a few seconds before night pick-ups so your baby can try to resettle.

Short Naps

Shift the next nap earlier by 15 minutes and add a wind-down. If a nap is stuck at 30 minutes for a week, try capping the last nap to protect bedtime.

Early Morning Wakes

Check light and noise. Many babies do best with blackout curtains and a steady low fan. Move the first nap later by 10 minutes every day until mornings stabilize.

Bedtime Protests

Keep the routine short and repeatable. Offer comfort in the crib with a calm voice and gentle touch. If feeds are part of bedtime, separate the last feed from lights-out by a few minutes.

Teething Or Illness

Comfort and care take the lead. Expect more wakes for a few nights. When your baby feels better, return to the usual routine.

How Much Should My Baby Sleep? With Signals To Watch

Ranges guide you, but your baby’s behavior seals the decision. If you keep asking “how much should my baby sleep?”, scan for bright daytime energy, steady growth, and a mood that recovers after brief fusses. Those signs matter more than a single number.

Sample Day Schedules By Age

These are starting points. Slide nap times by 15–30 minutes as wake windows stretch and watch your baby’s cues.

Age	Day Structure	Notes
0–3 months	Wake, feed, short play, nap; repeat 6–8 cycles	Naps 20–120 min; nights split by feeds
4–6 months	3–4 naps; bedtime around 7–9 pm	Last nap short to protect bedtime
7–9 months	2–3 naps; longer first nap	Practice new skills by day to calm nights
10–12 months	2 naps; bedtime 7–8 pm	Teething may add brief wake-ups
13–15 months	Shift from 2 naps to 1 midday nap	Use earlier bedtime during the transition
16–18 months	1 nap ~90–120 min	Keep a steady wake-up time when you can
1–2 years	1 nap; calm pre-nap routine	Many toddlers need 5–6 hours awake before bed
3–5 years	No nap or quiet-time	Bedtime stays steady to protect night length

When To Talk To Your Pediatrician

Check in if snoring is loud and steady, breathing looks labored, or your baby seems unusually sleepy or unusually short on sleep for weeks. Medical issues, reflux, or iron levels can affect rest. Bring a two-week sleep log with wake-ups, naps, and feeds so your clinician sees the pattern.

Wake Window Ranges By Age

Wake windows are the spans of time a baby stays comfortably awake between sleeps. They stretch with age. Use these as flexible starting points and adjust by 15–30 minutes based on your baby’s cues.

• 0–6 weeks: 30–60 minutes
• 7–12 weeks: 45–90 minutes
• 4–6 months: 1.5–2.5 hours
• 7–9 months: 2–3 hours
• 10–12 months: 2.5–4 hours
• 13–18 months: 3.5–5 hours
• 1–2 years: 4–6 hours

Bedtime Routine Builder

Pick 3–5 quick steps you can repeat anywhere. Keep lights low, voices soft, and finish with the same last step every time. A simple plan you can run in 10–15 minutes:

1. Feed if due, then burp and change the diaper.
2. Dim the room, close curtains, and turn on a steady low fan or white-noise.
3. Wash face and hands or give a brief bath on bath nights.
4. Read one short book or sing one song.
5. Place your baby on the back while drowsy but awake.

Environment Checklist

A dark, cool room and a clear crib help most families. Dress your baby for the room, not the calendar.

• Room: quiet, dim, and around 20–22°C
• Sound: steady low fan or white-noise
• Light: blackout curtains for early mornings and naps

Feeding And Sleep: What Helps

Full feeds by day support better nights. For newborns, feed on demand. Past 4 months, many families shift toward an eat-play-sleep flow so naps are not tied only to bottles or nursing.

Two-To-One Nap Transition

This shift often lands between 13 and 18 months. Signs it’s time: the second nap pushes bedtime late, the first nap runs very long, or your toddler resists one nap most days. Trim the morning nap to 30–45 minutes for a week, then move to one midday nap and edge bedtime earlier during the change.

Travel, Time Changes, And Growth Spurts

Anchor the day with a steady wake-up and the same first nap window you use at home. For a one-hour time shift, slide the schedule by 15 minutes every day.

Myths To Skip

• “Keeping baby up makes better sleep.” Overtired babies wake more, not less.
• “Rice cereal in the bottle improves nights.” This is not advised and can raise risks without clear sleep gains.

Baby sleep will ebb and flow. Use the ranges, watch your baby, and keep the routine steady. Over time, the nights add up.
