My little guy will be 6 weeks on the 16th. The last couple of days he's been sleeping a lot more. Instead of his "normal" eats about 3-4 oz is awake for 1-2 hours then asleep 3-4 hours. Its been eat about 1-2oz awake for about 1/2hour-1 hour, sleep 1-2 hours. So basically he's awake for maybe 4 or 5 hours out of the day. Wakes up more often to eat, but eats much less and sleeps more often, rather then is "normal" longer stretches of sleep, larger feedings, and staying awake for longer stretches. He isn't cranky, gassy or seeming to be having any tummy issues or anything. Just wants to sleep.
