How Much Sleep Do Babies Actually Need?

Questions about how much sleep a baby needs are among the most common concerns parents have. While every baby is different, there are well-established ranges that help guide expectations. Understanding these ranges is important because both under-sleeping and overtiredness can significantly impact sleep quality.

Newborns generally need the most sleep, with totals gradually decreasing as babies grow. By three to six months, sleep becomes more consolidated, and by six to twelve months, most babies require slightly less total sleep but benefit from more predictable patterns.

One of the most misunderstood aspects of baby sleep is the relationship between tiredness and night waking. When babies become overtired, their bodies produce higher levels of stress hormones, which can make it harder for them to fall asleep and stay asleep.
