What kind of baby cereal should I start my son on? Oatmeal or Rice?

My pediatrician told us that you really don't have to start with cereal. My baby had constipation problems with rice, and the doc said that starting with cereal is more "tradition than nutrition". Try getting a level 2 veggie (they say orange ones are best to start with like carrots and sweet potatoes) and mixing it with a little bit of any cereal you'd like. I started my baby off at 4 months and she really preferred the veggies anyway. Good luck!
