How Much Sleep Does a Baby Need? A Gentle Guide from Birth to 12 Month

If you're searching this at 3 a.m. with a baby who has decided sleep is optional, first: this is hard, and you're not doing it wrong. Baby sleep is confusing, and most of what's out there is either too clinical or a little judgy.

So let's keep it simple and honest. Below are typical sleep ranges for the first year. They are ranges, not targets. Plenty of healthy babies sit outside them, and no baby is failing a sleep test.

How much sleep does a newborn need (0–3 months)?

Newborns typically sleep about 14 to 17 hours in every 24, but not in tidy chunks. Expect stretches of roughly 2 to 4 hours, day and night, because tiny tummies need frequent feeds and newborns haven't developed a body clock yet.

What's normal at this stage:

Waking often to feed, including overnight
Sleeping a lot in the day and being more awake at night
Short, unpredictable sleep with no real "schedule"

There is nothing to fix here. Newborn sleep is a survival stage, and it does get better.

How much sleep does a 4 to 6 month old need?

Most babies in this range sleep around 12 to 16 hours a day including naps (this is the range recommended by the American Academy of Pediatrics). Night sleep starts to lengthen, and naps often settle into a more recognizable pattern of about three to four a day.

This is also when many parents hit the dreaded 4-month sleep regression. It's really a permanent change in how your baby's sleep cycles work, because their brain is maturing. It feels awful, but it's a sign of development, not a step backward.

How much sleep does a 6 to 9 month old need?

Total sleep still sits around 12 to 16 hours, with naps often dropping to two or three a day. Many babies can go longer stretches at night, though plenty still wake to feed, and that's normal too.

Growth spurts, teething, crawling, and separation anxiety can all disrupt sleep here. Disrupted sleep in this window is common and usually temporary.

How much sleep does a 9 to 12 month old need?

Most babies still need about 12 to 16 hours in total, with two naps a day for many. Night sleep is often at its most consolidated, but this is another common time for regressions (hello, 8 to 10 months) as babies learn to pull up, crawl, and cruise.

What if my baby sleeps less (or more) than these ranges?

Try not to panic. These numbers describe averages, and every baby has their own sleep needs. A better question than "am I hitting the number?" is:

Is my baby generally alert and content when awake?
Are they feeding and growing well?
Are they able to fall asleep with some support?

If the answer is mostly yes, your baby is probably fine. If you're worried about your baby's sleep, feeding, or development, talk to your pediatrician or child health nurse. You know your baby best.

Can you help a baby sleep better without cry-it-out?

Yes. Gentle approaches focus on responding to your baby, building a soothing routine, and working with their development instead of against it. You don't have to choose between sleep and a baby who feels safe. Your baby needs you responsive, and nobody gets an award for ignoring their cries.

A few gentle basics that help many families:

A simple wind-down routine (bath, feed, cuddle, book, bed) so sleep has a predictable start
Watching sleepy cues like yawning, staring, and rubbing eyes, and not just the clock
A calm, dark, cool sleep space that follows safe sleep guidelines

A note on safe sleep

Safe sleep always comes first. Current guidance from the AAP and Australia's Red Nose recommends putting babies to sleep on their back, on a firm, flat surface with nothing else in the sleep space. Follow local safe sleep guidelines, and ask your health provider if you're unsure.

The bottom line

Baby sleep changes constantly, and "normal" covers a huge range. If you're exhausted, that doesn't mean you're doing it wrong. It means you have a baby.
