How Much Sleep Does a Baby Need by Age (0–3 Years Chart)
Sleep needs change fast in the first few years. Knowing the typical total (naps + night) helps you set realistic expectations and spot when something's off. Here's the by-age guide.
Total sleep needs by age (naps + night)
Newborn (0–3 mo): 14–17 hrs · 4–11 mo: 12–15 hrs · 1–2 yrs: 11–14 hrs · 3–5 yrs: 10–13 hrs.
These are 24-hour totals. A 6-month-old sleeping ~11 hrs at night plus ~3 hrs of naps is right in range.
How that splits between naps and night
Newborns sleep in short chunks around the clock. By 3–4 months, night sleep consolidates and naps organize into a pattern. Most babies take 2 naps until ~15–18 months, then drop to 1 nap until around age 3–4.
If a nap steals from night sleep (or vice versa), total sleep is what matters — but very long late naps can push bedtime too late and cause early waking.
What if my child sleeps more or less?
Ranges are wide because children differ. Look at daytime behavior: a well-rested child is generally content, feeds well, and handles transitions. Persistent crankiness, frequent night wakings, and early-morning waking often signal not enough (or poorly timed) sleep. Talk to your pediatrician about any sudden or extreme change.
Key takeaways
- Newborns need 14–17 hrs; toddlers 11–14 hrs (naps + night).
- Most babies drop to one nap around 15–18 months.
- Judge by daytime mood, not just the number.
- Very long late naps can sabotage night sleep.

Is my baby sleeping too much?
Occasionally babies sleep more during growth spurts or illness. If your baby is unusually sleepy, hard to wake, or feeding poorly, contact your pediatrician.
My toddler skips naps but is fine — is that OK?
Some children drop naps earlier than others. If they're happy, not melting down late afternoon, and sleeping well at night, it can be fine. Watch for overtired bedtimes.
Does more daytime sleep mean worse night sleep?
Not usually for babies — overtired babies actually sleep worse. But for older toddlers, too much or too-late napping can delay bedtime.
