From birth to 3 months, most babies sleep for two thirds or more of a 24 hour period. The problem is, they don’t sleep all the way through, but instead wake up about every 3 hours for nourishment. This is actually perfectly normal. Babies follow a polyphasic sleep schedule, but will slowly begin to sleep longer at night and awake more during the day. It is quite normal for a newborn to wake up every 2, 3, or 4 hours to eat, unfortunately. If you are using formula, consider putting all the pieces together so that you won’t have to think too hard in the early morning hours. A vented bottle system helped my wife and me to keep gas to a minimum. We also used simethicone (Mylecon) quite a bit as well, for those hard to produce gas bubbles in babies’ belly.
