Pooping 10 times a day

Emma

My LO used to poop once a day then started pooping 10 or more times a day, her bum was so red and sore it was even bleeding. I took her to the doctor multiple times and eventually we got anti biotics. This cleared up her sore bum and she went back to pooping once a day. A week later she’s now back to pooping 10 times a day. She seems okay in herself but I’m worried, has anyone else had this?
