Newborns sleep a lot. They will be sleeping between each feeding for the first couple of weeks. Around the 4th week your baby will begin to stay awake between feedings. Before your milk supply is established, breastfed babies will feed a lot and may only sleep 1-2 hours between feeds. This will last 24-48 hours.
Do not put your baby on his or her stomach to sleep. The Canadian Pediatric Society recommends that the baby should be placed on his or her back to sleep until he /she is 12 months old. When the baby is awake, different positions are recommended. This gives the baby a new perspective and helps with the development of your baby. Call your doctor if you are concerned about your baby's sleep.
