My infant daughter was suffering from a rare case of a bacterial infection called C. Difficile, which caused horrible, frequent diarrhea for months until it was finally cured. As a result, she got a horrible case of diaper rash. The rash was horrible. It covered her entire diaper area and was bleeding. At one point, her diaper rash was so severe, parts of her skin were removed and there were open sores. We slathered on every available brand of diaper cream, tried prescription yeast creams, dried her bottom with a hair dryer, EVERYTHING. Finally, her gastroenterologist recommended Calmoseptine, which was available in the pharmacy at Kaiser.
