How much sleep does your baby need?
Pick your baby’s age. You’ll see the recommended total for a day, how naps usually fall, and how long they can comfortably stay awake between sleeps.

When did they last wake up?
Tell us, and we’ll say when the next nap is likely due.
Around 12 to 16 hours of sleep in a day, naps included.
Happily awake for about 2 to 3 hours between sleeps.
Typical wake windows parents and sleep consultants use, not a clinical guideline. The first window of the day is usually the shortest, the last before bed the longest.
General information, not medical advice. Every baby is different, and premature babies follow their own curve (count from the due date). If you’re worried about your baby’s sleep, breathing or weight, talk to your health visitor, paediatrician or doctor.
By age, at a glance.

Naps and wake windows, in plain words.
The time your baby can happily stay awake between one sleep and the next, from the moment they wake to the moment they’re back asleep, feeds and play included. Too short and they won’t be tired; too long and they get overtired and fight the nap. The windows above are the ranges parents and sleep consultants commonly use, not a medical rule.
It changes fast in the first year. Newborns sleep in stretches around the clock; by four to five months most babies settle into three or four naps; from six to eleven months, two or three; and somewhere between twelve and eighteen months most drop to one nap after lunch. Pick an age above and the moon says what’s usual.
Yes. The recommended hours are for the whole 24 hours, naps and night together. A baby who naps a lot may sleep a little less at night, and that’s normal.
The ranges are wide on purpose, and some babies sit outside them and are perfectly well. If your baby is settled, feeding well and gaining weight, a little less sleep is rarely a problem on its own. If you’re worried about your baby’s sleep, breathing or weight, talk to your health visitor, paediatrician or doctor.
Count from the due date, not the birth date, for the first year or two: a baby born eight weeks early who is four months old is closer to a two-month-old for sleep. Your paediatrician can tell you when to stop adjusting.
Total sleep by age is the American Academy of Sleep Medicine’s consensus, endorsed by the American Academy of Pediatrics. Under four months the AASM makes no recommendation, so we show the National Sleep Foundation’s range and say so. Wake windows are common practice, not a clinical guideline.

It logs every nap and feed with one tap and shows the pattern week by week in the Wellness tab, so you plan from your baby’s own day rather than an average. And when Auto-Soothe hears a cry, it can play a lullaby or your recorded voice before you’re up.
