My 10 month old started to get sick Monday with slight runny nose and cough. Two days ago started diarrhea and fever. Went to his pediatrician today. They said he has the flu. His cold symptoms are almost non existent but his diarrhea is so bad . He has it every 30 mins to an hour. His bottom is red and bleeding. I’ve use Boudreaux butt paste and aveeno. I’ve also have been doing the aveeno bath soaks. This only helps temporarily. He is crying and so upset when he poops and during diaper change. I try not to let him sit in a poopy diaper for long. The only time is when he is asleep. His pediatrician won’t give us any medicine for this!!?? Any recommendations?? He is so miserable
