It is my understanding that unless you are exclusively breastfeeding, baby needs solid foods to help make up nutritional gaps in formula once they reach about 6 months. We started with cereal at 6 months, then added in veggies, single ingredient to start. Once we got through the basic veggies we started fruits. from say 6-8 months we introduced a new food every week, and once he was doing well with eating in general we went from one meal a day to 3 meals a day. At 10 months he gets 2 snacks (puffs or cheerios or baby biscuits). fruit and cereal for breakfast, veg and cereal for lunch and dinner, and he still takes several bottles during the day.
Oh and we do juice or water in a cup when he eats.
I tried making my own baby food, but the texture was always off nomatter what I did and he wouldn't eat it so we gave up. I buy organic stuff when I have to buy baby food or snacks but I also get WIC and they provide food (beechnut brand) and we've had no problems with it, I actually really like that they have a stage 2.5 that is smooth but has little bits that are thicker in texture. My little guy has a sensitive gag reflex so we are a long way from anything lumpy.
