My One Year Old Has Only Been Able To Pass One Solid Stool In The Past Year, He Just Has Persistent Diarrhea, What Could Be Wrong?
My son is about to turn one in less then a week. He has had persistent diarrhea for as long as I can remember. I've switched his formula to soy and still no progress. It's starting to worry me and I'm looking for what it could possibly be. Thank you.
