all the books and dr's say wait at least 6 months. my baby weighed 9 lbs 5 oz at birth and is hungry. i know he is. he is 5 months old. i have been giving him cereal in the morning and at bed time and that has helped a lot. when do i give him fruit and veggies? i don't want to make him fat but he just doesn't seem satisfied. he now weighs 16.5 and is 26 inches long. advice please!
