Is my baby eating too much?

A baby will only eat if he is hungry. Mine at every hour and a half to start out with, and i had to put them on cereal at two weeks old. lol.... they grew up being very healthy and have never been over-eaters or fat. Every baby is different in how much they eat and when. They will let you know what they need. Talk to your doctor about your concerns so you won't worry about it anymore.
