Although many grandmothers and neighbors may swear that a little cereal in their newborn's bottle helped him sleep better, the American Academy of Pediatrics does not recommend introducing cereal and other solid foods until four to six months of age. Before that age, young infants need only breastmilk or formula. In the first couple of months of life, a newborn generally feeds every 2 hours. If you are breastfeeding, offer up to 10-15 minutes on each breast; for formula feeding, offer about 2-3 ounces at each feeding.
