Hello, I am a mother of 3 and one on the way. My first daughter had alot of medical problems so from the first days of life she had rice cereal ( about 1 teas.) in her bottle, but I didn't start feeding from a bowl ( rice cereal, and jar foods) until they could sit up well, and hold their head up. Even then I would feed them a little bit of sweet potatoes and things like that only once a day. If the baby spits up the food alot stop feeding them it and wait awhile longer. Good luck and most of all enjoy him.
