Newborns sleep for most of the day and night on average and wake up every few hours to feed. Overall, infants sleep a great deal more, averaging 14-17 hours a day for the first two weeks. They always wake up, though, and hardly sleep for longer than 4 hours, even at night. For first-time parents, it is difficult to know how long and how long a newborn should sleep.
Understandably, many parents want their children to sleep all night. The longer a baby sleeps, the longer its parents sleep. Unfortunately, most new parents have to accept that their baby wakes up several times at night. Most babies begin to approach the adult sleep pattern between three months and one year old. At that period, babies begin to sleep longer at night and shorter at daytime gradually.
