Ds2 went to the toilet tonight and then shouted "help, my bottoms bleeding". I ran in but in fact there was just a tiny bit of blood on the paper. On close inspection (presume no one eating their tea now) there was a small area right by the anus- like a burst ulcer or like a nappy rash burn type thing. I put some metanium on it but have never seen or heard of this problem before- any one else had this?
