My grandson, 8 months old, started a month ago haveing diarria five or more times a day, very bright green or very dark green, and smells aweful. for the most part a happy baby, but cant keep food from passing through the system too fast. He has been loosing a half pound weight a week since this started. We have tried several different formulas, been to three different pediatric doctors all say they dont know try someone else. The next doc to visit in two weeks is an infant GI doctor in st louis. Some are thinking maybe CF but not enough symptoms. He is a normal healthy on track 8 month old baby, just cant keep food from going through the body without absorbing the nutrients.
