I'm not sure if a rash is a symptom as well but when my ds turned 1 and was put on whole milk he also started developing some of the symptons you are describing (runny nose, diarrea, etc.). My ped. told me he was getting too much fat from the whole milk and had me switch to 2% milk. It solved the problem. Of course, I can't be sure this is the situation your lo is in but you may want to keep it in the back of your mind. Good luck. :wink:
