I had a nice friend of mine over today with her ds, who's 2 and a half. When her ds needed a nappy change, she asked where she should change him and I suggested upstairs in the bathroom. But her ds didn't fancy that so she did it on the sitting room floor (on changing mat). I wouldn't have minded if it was just a wet nappy, but a dirty and really smelly one?! I'm afraid it really grossed me out and the smell lingered for ages. My own dc's dirty nappies don't bother me at all, but this did. AIBU and too fussy?
