I know it's early and as a first time mom, very confusing. Also, any new doctor that you see will tell you to stay away from rice cereal. I started my son on rice cereal right at a month old. He was breastfed also. If you pump a bottle and add about a teaspoon to the bottle, it will make all the difference in the world. My son is now 3 and had no problems with it. He is not overweight and has no nutritional problems. Whatever you do, don't stop breastfeeding. About a month after he's good with that, I would start him on the rice cereal in a bottle 3 times a day. About the same time you would eat breakfast, lunch and before bed. This will also start him on a normal daily eating regimen. I.E. when it's time to eat a full meal. My "old-school" doctor made so much sense out of it. If you try to just drink water or milk all day, it wouldn't last you very long. To boot, if you compare breast milk to formula, it is like comparing water to cream. Breast milk is so thin and therefore there is no substance "sticking" to his belly to hold him over.
