My 14 month old drinks half Next Step, half milk in his sippy for breakfast and before bed. The doctor reccommended it until 18 months because of the iron in it, but we will probablly stop after this container is done. He doesn't drink that much of it and he does get a lot of other iron.
My 18 month old is still on Soy Formula. The dr. had wanted her on it for extra nutrition. She doesn't eat that much, and still only has one tooth. Also WIC in our state doesn't provide Soy Milk, just the Soy formula.
