It just depends on the pediatrician I think. I've had a pediatrician who told me it was ok to start giving my daughter cereal at 2 months while another suggested to wait until 4 months. It just depends on what they feel is best. Personally, I waited to make the switch til a year since the APA suggests to wait until a year; as children need the nutrients formula/breastmilk provides still at that point.
