Baby Only Drinks A Little

Sara

Today my 5.5 week old has been only eating little bits at a time both on the breast and the bottle. He eats a little, sleeps, wakes up and drinks a bit more, will stare off into space for a little while and eat again and then sleep. He's not fussy or anything but I can't figure out what hes doing today. Its not normal for him. Lots of pee and poop today but I just want to make sure that its normal.
