One week the third nap slots in perfectly; the next, your baby flatly refuses it and the whole afternoon wobbles. Daytime sleep is meant to change. Naps drop away gradually as your baby's body learns to stay awake for longer, and your job is mostly to follow their cues rather than force a timetable. There is a wide normal range, and your baby has not read the same chart you have.
Typical nap counts by age
These are gentle averages, not targets. Every baby is different, and a range either side is completely normal.
| Age | Naps a day | Rough total day sleep |
|---|---|---|
| Newborn (0–3 months) | 4–6 (often irregular) | 7–9 hours |
| 3–6 months | 3–4 | 4–5 hours |
| 6–9 months | 2–3 | 3–4 hours |
| 9–15 months | 2 | 2.5–3.5 hours |
| 15–24 months | 1 (long afternoon) | 2–3 hours |
The WHO notes that total sleep (day plus night) matters more than the exact split. By around 12 months most babies sleep about 11–14 hours over 24 hours, and the daytime portion shrinks as the nights settle.
When babies drop naps
Naps usually fall away at fairly predictable points, though the timing varies widely:
- 4 to 3 naps: often around 4 months as wake windows stretch.
- 3 to 2 naps: commonly between 6 and 9 months, once a third "catnap" stops fitting before bedtime.
- 2 to 1 nap: usually between 13 and 18 months. This is the longest, bumpiest transition and often takes weeks.
- Dropping the last nap: most often between 3 and 5 years, well beyond the baby stage.
| Age | Awake between sleeps |
|---|---|
| Newborn | 30-60 min |
| 3-4 months | 75-120 min |
| 5-8 months | 2-3 hours |
| 9-15 months | 3-4 hours |
| 15-24 months | 4-6 hours |
Signs a transition is coming
A single bad day is not a transition. Look for a consistent pattern over one to two weeks:
- Your baby suddenly fights a nap they used to take happily.
- Naps get shorter or one nap "disappears" no matter what you try.
- A nap pushes bedtime too late or causes early-morning wake-ups.
- Their wake windows naturally lengthen — they are still cheerful and alert well past the old nap time.
- More night wakings or early rising, which can paradoxically signal too much or too little day sleep.
If you see most of these for a week or two, gently nudge wake windows longer and shift the remaining nap(s) a little later rather than dropping a nap overnight.
Example 2-nap day (around 6-9 months)
- 6:45Wake & feed
- 9:00Nap 1
- 12:30Nap 2
- 15:30Optional short catnap (drops first)
- 18:30Bedtime routine
- 19:00Bed
Easing through a transition
- Go slowly. Move nap and bedtimes by 15–30 minutes every few days rather than all at once.
- Bring bedtime earlier temporarily. On days a nap is short or skipped, an earlier night helps avoid overtiredness.
- Keep the wind-down familiar. A consistent, calm pre-sleep routine signals "sleep now" through the wobble.
- Expect a few rough days. Transitions settle once their body catches up.
When to check in with someone
Daytime sleep that is a bit messy is normal. But have a chat with your GP or child-health nurse if your baby is very hard to settle for every sleep, seems excessively sleepy or hard to wake, or if sleep changes come alongside feeding problems, poor weight gain or you are worried about their breathing or development. If your own exhaustion is affecting your mood or coping, please reach out too — support is part of looking after your baby.
Regional note: AU (Raising Children Network, Red Nose), US (AAP / HealthyChildren) and the WHO all give broadly similar nap and total-sleep ranges, with small differences in exact hours. When in doubt, follow your local child-health service and your baby's cues.
