Baby Sleep Chart by Age: Total Sleep, Naps & Safe Routines

Quick answer

Baby sleep changes quickly and no single schedule suits every child. The American Academy of Sleep Medicine recommends 12–16 hours in 24 hours for infants aged 4–12 months and 11–14 hours for children aged 1–2 years, including naps. Newborn sleep is more variable, which is why the recommendation begins at 4 months.¹

Use the chart as a range, not a target to force. How a baby feeds, grows, breathes, wakes and behaves when awake matters more than matching a sample clock.

Baby sleep chart at a glance

Age	Recommended total sleep	Common nap pattern—not a rule	What often changes
0–3 months	No AASM numeric recommendation; patterns vary widely	Sleep is spread across day and night	Feeding and waking are frequent; day/night rhythm develops
4–6 months	12–16 hours including naps	Often 3–4 naps	Sleep may begin to consolidate
6–9 months	12–16 hours including naps	Often 2–3 naps	Longer awake periods; gradual move toward two naps
9–12 months	12–16 hours including naps	Often 2 naps	Mobility and separation awareness may disrupt sleep
12–18 months	11–14 hours including naps	Often 1–2 naps	Many toddlers gradually move toward one nap
18–24 months	11–14 hours including naps	Often 1 nap	A midday nap is common, but timing varies
2–3 years	11–14 hours at age 2; 10–13 from age 3	Often 0–1 nap	Some children still nap; others use quiet time

Total-sleep ranges come from the AASM consensus recommendation.¹ Nap counts and transition descriptions are broad practical patterns, not diagnostic standards.

How to use the chart

Count the full 24 hours

Add naps and night sleep across a typical day. One unusual day after illness, travel, vaccination, teething or a missed nap does not define a child’s pattern.

Look at a week, not a stopwatch

For five to seven days, note approximate sleep times, naps, wakes needing help, night feeds, alertness when awake, and any snoring or breathing pauses. Rough patterns are sufficient; stop tracking if it increases anxiety.

Use behaviour as context

A child near the lower end may be doing well if they wake alert, feed and grow appropriately, and function comfortably. A child who reaches the numeric total may still need assessment if sleep is very fragmented, breathing looks difficult or daytime behaviour has changed.

Do not force the chart

Do not keep a tired baby awake merely to “earn” night sleep. Make nap changes gradually and observe the pattern before making another change.

Flexible rhythms by age

These are rhythm examples, not prescribed schedules. Exact clock times can create false precision, so this guide focuses on adaptable rhythms.

Newborn to 3 months

Newborns usually sleep in short stretches across day and night. The goal is not to make a newborn “sleep through.” A routine can be as simple as feed according to the baby’s plan and cues, change, dim the environment at night, and place the baby on their back in a safe sleep space.

Ask the pediatrician whether a newborn needs to be woken for feeds, especially after premature birth, jaundice, low birth weight, feeding difficulty or slow weight gain. A sleep chart cannot make that decision.

4–6 months

A short repeatable sequence can signal sleep even when the time varies:

feed → clean nappy → dim lights → short song or story → safe sleep space

Keep it manageable. A long routine dependent on one person, product or perfect environment may become difficult for the family.

6–9 months

One refused nap does not mean the nap has disappeared. Watch for a repeated pattern: the nap remains difficult, bedtime shifts late, and the child comfortably manages the longer awake period. Change one thing at a time.

9–12 months

Standing, crawling, new sounds and separation awareness can temporarily affect settling. Keep the routine familiar, allow safe daytime practice of new skills, and check health or feeding concerns before labelling the change a “regression.”

12–18 months

Possible signs of a move toward one nap include repeatedly refusing one nap or bedtime becoming persistently late. Signs the change may be early include falling asleep every morning in the car, very difficult late afternoons, or repeated early-evening sleep. See Babynama’s one-nap transition guide for a detailed plan.

18 months to 3 years

A predictable routine and clear end point are more sustainable than adding a new negotiation each night. Children who stop napping may still benefit from a midday quiet period.

Safe sleep rules do not change because a schedule is difficult

For every infant sleep, AAP guidance recommends a firm, flat, non-inclined surface and placing the baby on their back. Keep pillows, loose blankets, bumpers, soft toys and other soft objects out of the sleep space. Room-sharing without bed-sharing is recommended for at least the first six months.²

Five-point check

Back: start every infant sleep on the back.
Flat: use a firm, flat, non-inclined surface.
Clear: no pillow, loose blanket, bumper, nest, soft toy or positioning product.
Separate: use the baby’s own sleep surface in the caregiver’s room for at least six months.
Comfortable: avoid overheating and dress for the room.

Do not use an inclined sleeper, positioner, pillow or weighted sleep product to lengthen sleep. Marketing terms do not establish safety for unsupervised infant sleep.

Always place a baby on their back at the start of every sleep. If the baby can roll comfortably in both directions and then rolls independently, AAP guidance says that repeated repositioning is unnecessary; keep the sleep space clear of blankets, pillows, toys and bumpers.²

When to speak with a pediatrician

Seek advice for a new or persistent pattern involving:

unusual sleepiness or difficulty engaging while awake;
settling or waking that is severely affecting the child or family;
regular snoring, gasping, noisy breathing or apparent breathing pauses;
repetitive unusual movements;
feeding or growth concerns alongside sleep concerns;
a sudden major sleep change without an obvious short-lived cause;
caregiver sleep deprivation that makes driving or childcare unsafe.

Seek emergency help if a child is struggling to breathe, turns blue or grey, is unusually difficult to wake, has a prolonged seizure-like episode, or appears seriously unwell.

Common chart mistakes

Treating wake windows as exact rules

Wake-window charts are not universal medical standards. At most, use them as loose planning ideas alongside the child’s cues and total sleep.

Comparing night stretches between babies

Children can reach a similar total through different combinations of naps and night sleep. Feeding, development, health, temperament and family rhythm all affect the pattern.

Changing everything together

If bedtime, nap count, sleep location and settling method all change at once, it is difficult to know what helped. Make one safe, manageable change and observe.

Calling every disruption a regression

“Regression” is descriptive, not a diagnosis. First check health, feeding, comfort, development, travel/routine disruption and safe-sleep conditions.

FAQs

How much sleep does a 6-month-old need?

The 4–12 month AASM recommendation is 12–16 hours in 24 hours, including naps.¹ The split varies; feeding, growth, alertness and breathing matter too.

How much sleep does a 1-year-old need?

At 12 months, the ranges move from 12–16 hours for infants aged 4–12 months to 11–14 hours for ages 1–2, including naps.¹ A birthday does not cause an immediate schedule change.

When do babies sleep through the night?

There is no single age, and the phrase has different definitions. Overnight feeding depends on age, growth and medical history; ask the pediatrician rather than using a sleep milestone alone.

When do babies move to two naps?

Many move from three toward two naps in later infancy, but timing varies. Look for a consistent pattern across several days, not one refusal. Timing varies from child to child.

When do toddlers move to one nap?

Many transition during the second year. Use the one-nap guide for a gradual plan, and seek advice if sleep, breathing, behaviour, feeding or growth is concerning.

Should I wake a newborn to feed?

It depends on age, weight, feeding effectiveness, jaundice, prematurity and the pediatrician’s plan. A generic chart cannot answer this safely for every baby.
