I started Colton early.. like 9/10 weeks (about 2-2.5 months). He started with baby rice, then moved to fruits about a week later.
He eats like crazy though, still. He eats three meals a day (totaling almost 6oz of food), aswell as 30-34oz of formula, and about 6oz of juice! He's always been a bigger baby though.
Oh, he also doesn't like baby rice.. not the powdered kind anyway. I feed him the breakfast jars... like, "rice cereal with apples" "rice cereal with peaches" etc.. he seems to love the jars but not the boxed cereal.
