Baby nap transitions: how many naps by age and when they drop

Babies start life with sleep spread across the day and night, then gradually settle into three naps, then two, then one. KidsHealth's guide to naps says most babies from 4–12 months take two to three daytime naps, and most toddlers drop to one nap by 18 months. Many children then give up the last nap somewhere in the preschool years (3–5). The exact timing varies a lot, so your baby's cues matter more than a birthday.

This guide is the overview. Each transition after the first has its own page: three to two naps, two naps to one and dropping the last nap. For full by-age timetables, see baby sleep schedules by age and wake windows.

How many naps does a baby need at each age?

The table pulls together what several children's health services describe. Treat it as the usual range, not a target.

Sources: Nationwide Children's Hospital, the Royal Children's Hospital Melbourne sleep review, KidsHealth on 4- to 7-month-olds, 8- to 12-month-olds and 1- to 2-year-olds.

Naps are part of total sleep, not extra. The American Academy of Sleep Medicine recommends 12–16 hours per 24 hours (including naps) from 4 to 12 months, 11–14 hours from 1 to 2 years and 10–13 hours from 3 to 5 years. As night sleep grows, the daytime share shrinks, which is what drives each transition.

How long do baby naps usually last?

Nap length varies more than nap number. KidsHealth says some 8–12-month-olds nap for 30 minutes while others nap for up to 2 hours. The Royal Children's Hospital describes day sleeps of up to two hours each from 2–6 months, and 2–3 hours of day sleep in total from 7–12 months, usually as a morning and an afternoon sleep. Nationwide Children's puts total daytime sleep between 2 and 5 hours for babies aged 2–12 months.

Short naps are common, especially early on. An infant's sleep cycle lasts about 20–50 minutes, compared with around 90 minutes for an adult, and the RCH review notes that many babies "cat nap" for a single cycle during the first year. If short naps are the main issue, see short naps and catnapping.

What are the signs a nap transition is coming?

A transition is a pattern, not a single day. Teething, illness, a growth spurt or a sleep regression can all scramble naps for a few days without meaning a nap needs to go. Signs many families notice over a week or two:

• Your baby fights or plays through a nap they used to take easily. KidsHealth says a toddler who fights the morning nap is probably ready for just an afternoon nap.
• A nap gets shorter and shorter, or takes a long time to fall asleep for.
• The last nap of the day runs late and pushes bedtime back. The Better Health Channel notes that an afternoon nap too close to bedtime can disrupt night sleep.
• Your baby stays cheerful and alert for longer, without the tired signs they used to show at that time.
• Night sleep or the morning wake-up starts to slip, with no illness to explain it.

It helps to jot down nap start and end times, how long each nap took to fall asleep for, bedtime and morning wake time for a week or two. That makes it easier to tell a real shift from a run of bad days, and gives a GP or child-health nurse something concrete to look at.

When do babies go from four naps to three?

The move from four naps to three usually happens in the early months. Nationwide Children's says 2-month-olds take two to four naps, and the RCH describes two or three day sleeps from 2–6 months, so the fourth nap tends to fall away somewhere between those points as your baby manages longer awake stretches. There is no single right week for it.

Signs your baby may be ready: the last catnap of the day is hard to get, it pushes bedtime late, or naps are steadily longer so four no longer fit before bedtime.

How to move from four naps to three

1. Watch for a steady pattern over about a week before changing anything.
2. Stretch awake time gently. Push the first nap a little later every few days, rather than all at once, while watching for tired signs such as staring, frowning or yawning.
3. Keep the last nap short so it ends well before bedtime.
4. Use an earlier bedtime on short-nap days. If the three naps don't add up to much, bring bedtime forward a little rather than adding a nap late in the evening.
5. Expect a mixed couple of weeks. The RCH notes that parents can see weeks of mixed sleep patterns while children adjust, so it's fine to offer a fourth catnap on a day your baby clearly needs it.

This is a fictional example built from the ranges above, not a target. For a fuller picture at this age, see the 3–5 month sleep schedule.

When do babies drop from three naps to two?

Most babies move from three naps to two somewhere in the second half of the first year. KidsHealth describes at least two naps from 4–7 months and two naps for most 8–12-month-olds. The usual sign is a third, late-afternoon catnap that becomes a battle or pushes bedtime late. See three to two naps for readiness signs, steps and example days.

When do toddlers move to one nap?

KidsHealth says that at around 18 months, or sometimes sooner, most toddlers combine their two naps into one afternoon nap, and the RCH review describes the same shift at around 18 months. It is often the bumpiest transition, with weeks of one-nap and two-nap days. See two naps to one.

When do children stop napping altogether?

The last nap usually goes during the preschool years. KidsHealth says many 3–5-year-olds give up their afternoon nap, while the Better Health Channel says children still need a daytime nap until around 2½ to 3 years even if they sleep well at night. When the nap goes, quiet time and an earlier bedtime help. See dropping the nap and toddler sleep.

Where should my baby nap, and is it OK in the pram or car seat?

Naps follow the same safe-sleep rules as night sleep, every time.

• On the back, every sleep. The NHS SIDS guidance says to follow its advice whenever your baby is sleeping, which includes day naps.
• Firm, flat, clear surface. Use a cot or bassinet with a firm, flat mattress and nothing in it that could cover your baby's face: no pillows, bumpers, loose blankets or soft toys.
• Same room for at least 6 months. Red Nose, the NHS and the AAP all advise baby sleeps in their own safe sleep space in the same room as a parent or carer for at least the first 6 months, for day sleeps as well as night.
• No inclined or weighted products. The AAP says any surface inclined more than 10 degrees isn't safe for sleep, and warns against weighted blankets, sleepers and swaddles.
• Car seats, prams, swings and slings. If your baby falls asleep in one, the AAP says to move them to a firm sleep surface on their back as soon as possible. The NHS also says not to leave your baby in a car seat for too long.
• Never on a sofa or armchair. Red Nose says never to sleep with your baby on a sofa, armchair or recliner, no matter how tired you are. If you feel drowsy while holding your baby, put them in their own sleep space first.

For a calm nap space, the Better Health Channel suggests a dark, quiet room. A consistent short wind-down before naps helps many babies too. See sleep environment and safe sleep for the full checklist.

When should I get help with my baby's naps?

Messy naps are very common and usually not a health problem. Get help if sleepiness comes with signs of illness. The NHS urgent help guide lists the signs below.

Call your local emergency number (000 in Australia, 999 in the UK, 911 in the US) now if your baby:

• is difficult to wake, cannot be woken, or is floppy
• is breathing very fast or struggling to breathe, grunting or sucking in their tummy
• has blue, grey, pale or blotchy skin, lips or tongue
• is having a seizure (fit)
• is under 3 months old and has a temperature of 38°C (100.4°F) or higher
• is much sleepier than usual and not feeding

Get same-day medical advice (your GP or a health advice line (Pregnancy, Birth and Baby on 1800 882 436 in Australia, NHS 111 in the UK, your pediatrician's after-hours line in the US)) if your baby is feeding much less than usual, has had far fewer wet nappies, or you are worried and not sure what to do.

Mention it at your next check with a GP or child-health nurse if naps are a struggle almost every day for weeks, settling for every sleep is very hard, or sleep worries are wearing you down. The RCH review notes that a parent's concern about their child's sleep is reason enough to talk to a professional. If exhaustion is affecting how you feel, see sleep deprivation. If you have thoughts of harming yourself or your baby, call a crisis line (Lifeline on 13 11 14 in Australia, Samaritans on 116 123 in the UK, 988 in the US) or your local emergency number (000 in Australia, 999 in the UK, 911 in the US) now.
