Well I was going to put Arse Acne, because that's what it looks like... Anyway, DS is 3 and recently potty-trained. SInce he got out of nappies he has started getting spots, just like zits, on his buttocks. THey don't seem to bother him, and I have a theory that they might be caused by him sitting on the plastic cover of the kids toilet seat. Has this happened to anyone else's DC and if so how did you treat it?
