My little guy is 3.5 months old. He feeds every 2-3 hours during the day and is awake for 2-3 hours between naps (sometimes longer). He'll nap anywhere from 20 minutes to 2-3 hours. At night we can't get him to bed any earlier than 10pm but then he sleeps until 4 or 5am, has a feed, then sleeps for another 3-4 hours before he wants to get up and start his day.
