He will probably let you know when he is ready for a mid-day meal...right now the formula is still his major form of nutrition...but when he starts crawling and getting more mobile he may need more calories. You will know...he will fill you in!! lol If you want to...start offering him a mid-day "snack" and see if he likes it or if it interferes with the formula that he takes in the afternoon.
