2 month baby sleep

Babies sleep all the time! Newborns and infants spend their time eating and sleeping and briefly playing in between. The time that they are active is quite limited and this is nothing to worry about. In fact it is essential that a baby is allowed to sleep as long as he wants. Otherwise he will throw tantrums and start crying and this is the last thing that you need. If your baby sleeps for more than four hours at a time it might be good to wake him or her up. Too much of sleep might not be a good thing as well and parents have to find the right balance.

Every baby's sleep needs are unique but babies at this age sleep a little less than they did as newborns, about 15 to 16 hours on average. Your baby will sleep most of these hours at night and will stay awake much longer during the day, although he/she'll be working his/her way toward three naps a day. As always, this varies with the baby.
Don't be surprised if your baby starts to be "hyperawake" and crying in the late afternoon or evening. This fussiness is normal. When he/she does settle, baby is likely to sleep longer.
