were you while you were pregnant and or nursing? I avoided all caffeine, nutrasweet and anything artificial while pregnant. When nursing I avoided caffeine and limited my nutrasweet (1 diet soda per day). I was also careful with fish and tried to keep things as natural as possible. My pediatrician told me that caffeine and nutrasweet were fine, but I still feel guilty and worry about that 1 soda per day ( I've since stopped). Anyone else out there feel similarly or had similar experiences?
