In the early weeks it can feel like your baby does nothing but sleep — yet you’re somehow exhausted. Both things are true, because newborn sleep comes in short bursts at all hours. Here’s what’s normal, and how it changes over the first year.
How much do newborns actually sleep?
A newborn sleeps roughly 14 to 17 hours a day, but rarely for more than 2 to 4 hours at a time. That’s because their stomachs are tiny and they need to feed often, day and night. They also haven’t yet developed a circadian rhythm — the internal body clock that tells the rest of us when it’s night — so a 3 a.m. wake-up feels no different to them than a 3 p.m. one.
This round-the-clock pattern is completely normal and, importantly, temporary. It’s biology, not a habit you’ve accidentally created — and there’s nothing you need to “fix” about a newborn who wakes often to feed.
How does baby sleep change month by month?
Total sleep slowly decreases and consolidates into longer stretches as your baby matures. Rough averages over the first year:
| Age | Total sleep / 24h | Typical pattern |
|---|---|---|
| Newborn (0–6 weeks) | 14–17 hours | Short 2–4h bursts, no day/night rhythm |
| 3–4 months | 13–16 hours | Longer night stretches start to emerge |
| 6 months | 12–15 hours | ~2–3 daytime naps; longer nights for many |
| 9 months | 12–14 hours | Often 2 naps; some sleep through |
| 12 months | 11–14 hours | Usually 1–2 naps; longer night sleep |
Treat these as gentle guides, not targets. Healthy babies vary widely, and a baby who sleeps a little more or less than average is usually just fine.
How many naps does a baby need?
Daytime sleep is just as important as night sleep, and the number of naps slowly drops as your baby grows. In the newborn weeks there’s no real nap “schedule” at all — sleep is scattered across the day. A loose picture of how naps consolidate:
- Newborn: frequent, irregular naps with no set pattern.
- 3–4 months: often 3–4 naps as a rough rhythm appears.
- 6 months: usually settling toward 2–3 naps.
- 9–12 months: commonly 2 naps, often dropping toward 1 near the first birthday.
Watching your baby’s awake windows — how long they can comfortably stay up between sleeps — is usually more useful than the clock. Those windows are very short for newborns (often under an hour or so) and lengthen as your baby matures.
When will my baby sleep through the night?
This is the question every tired parent asks — and the honest answer is it depends. Many babies manage a 5–6 hour stretch from around 3–6 months, which sleep researchers often count as “sleeping through.” But plenty of perfectly healthy babies don’t do this consistently until much later, and night waking commonly returns around developmental leaps, teething or illness.
If you’re counting weeks until a full night’s sleep, it helps to expect a gradual, non-linear trend rather than a single magic night. You may also hear about “sleep regressions” — stretches where a baby who was sleeping well suddenly wakes more, often lining up with big developmental leaps. They’re temporary and, frustrating as they are, usually a sign your baby is busy learning something new.
Why is my newborn awake all night and sleepy all day?
Day-night confusion is very common in the first weeks, because that body clock hasn’t kicked in yet. You can gently encourage the rhythm to develop:
- Make days bright and a little noisy — open the curtains, go about normal activity.
- Keep night feeds calm, dim and boring — low light, minimal talking, straight back to sleep.
- Watch for tired cues (yawning, looking away, fussing) and offer sleep before overtiredness sets in.
These nudges won’t flip a switch overnight, but over a couple of weeks they help your baby learn that night-time is for sleeping.
Safe sleep: the non-negotiable basics
However your baby sleeps, safe-sleep practices matter most. The widely-accepted basics are:
- Back to sleep — always place your baby on their back for every sleep.
- A firm, flat surface — a safety-approved cot or crib mattress.
- A clear sleep space — no loose blankets, pillows, bumpers or soft toys.
- Their own space — baby sleeps in their own cot, ideally in your room for the early months.
Guidance varies slightly by country and updates over time, so always follow your local health authority and your provider for the current advice.
How can you cope with broken sleep?
Newborn sleep is relentless, and looking after yourself isn’t optional:
- Sleep when you can, including short daytime rests — “sleep when the baby sleeps” is a cliché because it genuinely helps.
- Share the load where possible, alternating night duties with a partner or support person.
- Lower the bar on everything else for a few weeks; the early fog really does lift as your baby’s sleep slowly matures.
If you’re ever worried about your baby’s sleep, breathing or feeding, your health visitor, midwife or doctor is the right person to ask.
