A note before you read on: this article is general education, not medical advice. Every baby is different — always follow your own pediatrician's guidance, and call them (or emergency services) for any urgent concern about your baby's health.

If you've spent your baby's first week googling "how much should a newborn sleep" at 3 a.m., you're in good company. The honest answer is: a lot, in total — and almost none of it in a way that resembles a schedule. Understanding the shape of newborn sleep, rather than chasing a number, is usually the more useful goal in these early weeks.

The first two weeks: sleep in short, unpredictable bursts

Newborns typically sleep in stretches of one to three hours at a time, day and night, waking mostly to feed. Total sleep across 24 hours tends to be high, but it arrives in fragments rather than one long block — which is exactly why it doesn't feel restful to the adults around them. Day/night confusion is common in these early weeks: your baby's internal clock hasn't caught up with the outside world yet.

Weeks three to six: the fussy stretch

Many families notice sleep gets harder, not easier, around three to six weeks — often alongside a fussier evening stretch some people call "the witching hour." This is a normal developmental phase for many babies, not a sign you're doing something wrong. Short, frequent naps are still typical during the day.

Around six to twelve weeks: a rhythm starts to emerge

Somewhere in this window, many babies begin stringing together a somewhat longer stretch of nighttime sleep, and daytime naps start to look a little more predictable. "Somewhat longer" is doing a lot of work in that sentence — a four- or five-hour stretch counts as a big win at this stage, and plenty of babies aren't there yet, which is also normal.

Wake windows as a gentler alternative to the clock

Rather than watching the clock for a specific bedtime, many families find it easier to watch their baby's wake windows — the amount of time a baby can comfortably stay awake before becoming overtired. In the newborn period this is often quite short, sometimes under an hour, lengthening gradually over the following months.

What's worth mentioning to your pediatrician

  • Sleep that seems paired with poor weight gain or feeding difficulty
  • Breathing that sounds labored, or pauses, during sleep
  • A baby who is unusually difficult to wake for feeds
  • Your own exhaustion or mood — postpartum sleep deprivation is worth raising with your own provider, not just your baby's

None of the general ranges above are a substitute for your pediatrician's read on your specific baby. If something feels off, it's always reasonable to ask.
