my ds came up in hives all over last friday. very hot to the touch and swollen - looked like big white insect bites on a red background. Very strange. He was at nursery and hadnt eaten anything new, no new washing powder, no suncream - has anybody got any ideas? They went down after about 1 1/2 hours. Should I take him to the doctor or not. We had a scare the week before cos we thought he'd got chicken pox - but it wasnt and may have been a much more minor outbreak of the same. Seemed fine in himself apart from that. Has anybody had a child who's had similar reaction to something??
