My dd is 3 months and spits up constantly. She was on Enfamil newborn for the first two months and although she spit up some, it wasn't that bad. She has been on the regular enfamil premium for about 6 weeks and she spits up constantly now. A few weeks back I took her to the doctor and she prescribed some zantac and said to put a teaspoon of cereal per once in her bottles. Well, that didn't really help that much. The poor baby keeps a rash under her neck because it is near impossible to keep that area dry. I want to try a different formula to see if that will fix the problem, but what do you recommend?

I'm more inclined to try the Prosobe over the A.R. being that the zantac didn't really help. What do you think? I wanted them to change her formula in the first place, so I wanted to pick up a can and see how the results were before going back to the doctor and having to do all that mess with wic. Any input is appreciated.
