Three to two naps: when babies drop the third nap and how

Most babies drop from three naps to two somewhere in the second half of the first year. KidsHealth says most 8–12-month-olds take two naps, and a Royal Children's Hospital Melbourne sleep review describes day sleep from 7–12 months as usually a morning and an afternoon sleep. The third nap, a short late-afternoon catnap, is the one that goes. The tricky part is the long stretch from the last nap to bedtime while your baby adjusts.

For the bigger picture of how naps change with age, see naps and nap transitions. For full timetables at this age, see the 6–8 month sleep schedule.

When do babies go from three naps to two?

There is a wide range, and both ends are normal.

• KidsHealth on naps says babies from 4–12 months usually take two to three daytime naps.
• KidsHealth on 4- to 7-month-olds says babies this age need at least two naps, with about 3–4 hours of day sleep in total.
• KidsHealth says most 8–12-month-olds take two naps, each lasting anywhere from 30 minutes to 2 hours.
• A sleep psychologist quoted by the University of Colorado Department of Pediatrics says the move from three naps to two typically happens between 6 and 9 months.

So some babies make the switch before 6 months and some closer to their first birthday. What matters is whether your baby copes, not the date.

What are the signs my baby is ready for two naps?

Look for a pattern most days over a week or more, not one off day:

• The third nap becomes a battle. Your baby chats, plays or cries through the late catnap, or takes ages to drift off.
• Bedtime keeps getting pushed late. The Better Health Channel notes that an afternoon nap too close to bedtime can disrupt night sleep.
• The first two naps are getting longer, so there's no longer room for a third before bed.
• Your baby is happy for longer. They stay content well past the time they used to show tired signs.
• Nights or mornings start to slip. New night wakings or earlier mornings, with no illness or teething to explain them, can mean too much day sleep.

Not ready yet often looks like: falling asleep in the car or at the breast in the late afternoon, big meltdowns before dinner, or needing the third nap to make it to bed at all.

How do I move my baby from three naps to two?

Most families find a gradual change gentler than dropping the nap overnight.

1. Push the first nap later. Every few days, nudge the morning nap a little later, as long as your baby isn't overtired. This shifts the whole day along.
2. Let the second nap move into the early afternoon. With a later first nap, the second naturally falls after lunch, which helps cover the afternoon.
3. Shrink the third nap. Keep it short and make sure it ends well before bedtime. Some days your baby will skip it, and that's fine.
4. Bring bedtime forward on two-nap days. An earlier bedtime covers the gap until your baby can manage the longer stretch.
5. Allow mixed days. The RCH review notes that parents can see weeks of mixed sleep patterns as children adjust. Offer the third nap on days your baby clearly needs it.
6. Give it a couple of weeks before deciding whether it's working.

Don't cut naps to try to improve nights. Nationwide Children's Hospital warns that cutting back on naps to encourage night sleep results in overtiredness and a worse night.

What does a day look like before and after?

These are fictional examples built from the ranges above. They show the shape of the change, not targets.

Example three-nap day (around 6 months) — adjust to your baby

Example two-nap day (around 8 months) — adjust to your baby

The three-nap day gives about 3 hours of day sleep, in line with KidsHealth's 3–4 hours for 4–7 months. The two-nap day gives about 2.5 hours, within the RCH's 2–3 hours for 7–12 months. Total sleep across 24 hours stays within the American Academy of Sleep Medicine range of 12–16 hours, including naps, for 4–12 months.

How do I handle the overtired late afternoon?

The gap between the second nap and bedtime is where this transition bites. Better Health lists tired signs in older babies such as losing interest in toys, fretfulness, yawning, separation anxiety and crying, and advises settling a child before they become overtired and agitated.

• Move bedtime earlier. On days the naps are short, an earlier bedtime is usually the simplest fix, even if it feels very early for a while.
• Offer a short rescue catnap on hard days, and keep it brief so it doesn't push bedtime late.
• Plan an easy late afternoon. A walk outside, a bath or calm floor play works better than errands or busy outings.
• Keep dinner and the routine simple so bedtime isn't delayed.
• Expect a dip. Some babies are more unsettled for a week or two and then adjust.

For more on spotting and handling overtiredness, see overtired baby. For the full picture on how long babies can stay awake, see wake windows. The Sleep Foundation's commonly used ranges, a practical convention rather than clinical guidance, run from 1.5 to 4.5 hours at 5–7 months and 1.5 to 6 hours at 7–10 months.

Is my baby too young to drop the third nap?

It may be too early if, after a week or two of trying, your baby:

• is falling apart every late afternoon even with an early bedtime
• falls asleep in the car or during feeds before bed most days
• starts waking more overnight or much earlier in the morning
• seems more unsettled overall

If so, go back to three naps for a week or two and try again. Some babies drop the third nap, need it back during a busy or sick patch, then drop it again.

If your baby was born early, many parents find it helps to think in terms of corrected age (age counted from the due date) when comparing with typical ranges. Twins may be ready at different times; some families keep naps lined up and let the twin who needs it have a short extra catnap.

How do I keep naps safe during the change?

A changing nap pattern means more naps on the go. NICHD Safe to Sleep says to place babies on their backs for naps and at night, on a firm, flat surface clear of soft objects. If your baby falls asleep in a car seat or pram, move them to their usual sleep space as soon as possible.

It can help to note nap times, how long each nap lasted and bedtime for a week or two. That makes it easier to see whether the two-nap days are working.

When should I get help?

Nap transitions themselves aren't medical problems, but illness can look like tiredness. Use the NHS urgent help guide: call your local emergency number (000 in Australia, 999 in the UK, 911 in the US) now if your baby is difficult to wake, floppy, struggling to breathe, has blue, grey or blotchy skin or lips, or is having a seizure. 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 unusually sleepy and not feeding. Mention it at your next check with a GP or child-health nurse if sleep has been hard most days for weeks or you're struggling to cope.
