We started with rice cereal in the bottles VERY early because of our drs recommendation to help ease with reflux. But he had barley and oatmeal cereal at about 4/5 months. And we tried slowly with the veggies–no fruits. We still at 9 months are going VERY slowly with the fruits. He doesnt eat a lot of the jar fruits at once. I give him more little pieces of fruit to chew on he gets less into his tummy and it seems easier on him.
