Today is the day I'm going to try rice cereal with my little man. Does anyone have any suggestions? The Dr said it does not replace his bottle, so I was wondering how others give it to their baby. Do you give some cereal in the bowl before, during, or after the feeding? He normally has 6ozs of formula at feedings. Should I give him 4 oz and then some of the watered down cereal?
