My son had an ear infection last week, and was prescribed amoxicillin for 10 days. He has had diarrhea for literally the entire time just about that he’s been on it. (Luckily he’ll be done with the course tomorrow). Anyway, I’m not sure if he’s got a diaper rash, a yeast diaper rash, or just a sore butt from wiping and what not. I feel soo bad though. He has never had a diaper rash, and I put a&d ointment on him EVERY diaper change. What could I put on him that will clear it up? Or what should I do? Thanks so much in advance.
