B..
I never gave cereal. No nutrition, really...unless you're doing oatmeal or barley. I started with some fruits and veggies at 6 months. By 10 months he was eating table foods, but formula was still his main nutrition. At 12 months we took him off formula and he's been eating whatever we eat ever since. I never did juice. My son is 22 months and he only occasionally gets very watered down juice. My pediatrician approves this, he hates juice for kids. Zero nutritional value.
