Fourteen to seventeen hours a day, almost none of it in a row
Newborns sleep a lot. They just do it in short pieces, around the clock, with no idea that night is different from day. Nothing has gone wrong.
Quick answer
Newborns aged 0 to 3 months sleep about 14 to 17 hours in every 24, according to the National Sleep Foundation consensus recommendations, but in stretches of roughly two to four hours at a time. They have no established body clock at birth, which is why night and day feel identical to them for the first several weeks. Most babies begin to consolidate longer night stretches somewhere between 8 and 12 weeks, though the range is wide and there is no deadline. Track patterns rather than fighting them, keep nights dark and quiet and days bright and social, and follow safer sleep guidance every single time: on their back, on a firm flat separate surface, with nothing loose in the sleep space.

is a typical single stretch in the newborn weeks, driven largely by how often they need to feed.
is when many babies start consolidating longer night sleep, though the normal range is genuinely wide.
Why newborn sleep looks nothing like adult sleep
Two things drive it. First, a newborn stomach is small and breast milk digests quickly, so hunger interrupts sleep every few hours by design. Second, the circadian rhythm that tells the rest of us when to sleep is not yet developed at birth, and melatonin production takes weeks to establish. Your baby is not confusing night and day. They have not yet learned that the distinction exists.
Newborns also spend a much larger share of their sleep in active, lighter sleep than adults do. That is why they twitch, grimace, grunt and make noise while genuinely asleep, and why picking them up at the first squeak often wakes a baby who was going to resettle.
What is typical by age
| Age | Total sleep per 24 hours | What it usually looks like |
|---|---|---|
| 0 to 6 weeks | Around 14 to 17 hours | Short stretches day and night, waking to feed every two to four hours. No pattern to speak of. |
| 6 to 12 weeks | Around 14 to 17 hours | Slightly longer night stretches begin for many babies. Days start to look a little more organised. |
| 3 to 4 months | Around 12 to 16 hours | Naps often start to consolidate. Some families notice sleep temporarily becoming more broken again around this point. |
Treat these as broad ranges. A baby at the lower end who is feeding well, gaining weight and alert during wakeful periods is not short of sleep just because a chart says so.
Safer sleep, every sleep
This part is not flexible and it applies to naps as well as nights. Guidance from the NHS and the American Academy of Pediatrics is consistent on the essentials.
- Always on the back to sleep, never the front or side
- On a firm, flat, separate sleep surface with a well-fitting sheet
- Nothing loose in the sleep space: no pillows, duvets, bumpers, pods or soft toys
- Feet to the foot of the cot, with any blanket tucked in and no higher than the shoulders
- Room sharing without bed sharing is advised for at least the first six months
- Keep the room at a comfortable temperature and avoid overheating
- Never sleep with your baby on a sofa or armchair
If you are considering bed sharing, talk to your midwife or health visitor about how to do it as safely as possible, and be aware that it is not advised if anyone has smoked, drunk alcohol or taken medication that causes drowsiness, or if the baby was premature or low birth weight.
Things that genuinely help in the early weeks
- Make days and nights different. Daylight, normal household noise and interaction during the day; dim light, minimal talking and no eye contact during night feeds. This is the main thing that helps a body clock develop.
- Watch awake windows, not the clock. Newborns often manage only around 45 to 60 minutes awake before needing sleep again. Overtired babies are harder to settle, not easier.
- Pause before responding. Grunting and squirming often precede resettling. A short pause tells you whether they are actually awake.
- Track a week of it. Sleep in the newborn period feels random until you see it written down, at which point patterns and awake windows become obvious.
- Sleep when you can, not when advised to. The advice to sleep when the baby sleeps is impractical for most mums, but protecting one predictable stretch with help from a partner or family member is realistic.
Broken sleep takes a real toll, and it is worth treating your own recovery as part of the picture rather than an afterthought. We cover that in postpartum sleep and core recovery and beating new mum fatigue without relying on coffee.
When to speak to someone
Ask your midwife, health visitor or GP if your baby is very difficult to wake for feeds, is sleeping far more than expected and feeding poorly, is consistently unsettled and inconsolable, has any breathing that concerns you, or is not gaining weight as expected. Also ask for support for yourself if you are struggling. Exhaustion that tips into persistent low mood, anxiety or feeling unable to cope is common, treatable and worth raising early.

Frequently asked questions
How much should a newborn sleep?
About 14 to 17 hours in every 24 for babies aged 0 to 3 months, according to National Sleep Foundation consensus recommendations, spread across short stretches rather than long blocks.
When will my baby sleep through the night?
Many babies start consolidating longer night stretches between about 8 and 12 weeks, but the range is wide and plenty of healthy babies take considerably longer. Night waking through the first year is normal, and regular night feeds are expected in the early months.
Why does my newborn grunt and wriggle in their sleep?
Newborns spend a large proportion of sleep in active, lighter sleep, which involves noise, twitching and facial movement. It usually means they are asleep rather than waking, so a brief pause before responding is often useful.
How long should a newborn be awake between sleeps?
Often only around 45 to 60 minutes in the first weeks, including the feed and a nappy change. Watching for early tired signs such as staring, jerky movements or turning away tends to work better than watching the clock.
Is it safe for my newborn to sleep in my bed?
Guidance advises room sharing without bed sharing for at least the first six months, and bed sharing is specifically advised against if anyone has smoked, drunk alcohol or taken sedating medication, or if the baby was premature or low birth weight. Never sleep with your baby on a sofa or armchair. Discuss your situation with your midwife or health visitor.

This article is general education, not medical advice. Safer sleep guidance should be followed for every sleep, and your midwife, health visitor or GP's advice takes precedence over anything here. Experiences vary from mum to mum. Seek urgent medical advice if your baby is difficult to rouse, breathing abnormally, feeding very poorly, or if you are concerned about their wellbeing or your own.
