My DD 15 months had her MMR 6 weeks ago. This weekend have noticed a rash over her arms and legs - nowhere else. Did the glass test and ok. Could this be a delayed reaction to MMR? She hasn't got a temperature but is teething and we have had a bit of grizzly clingy day. Also has a bit of a runny nose and sore bottom which she usually gets when teething. Could the rash be anything to do with teething? I did ring local on call nurse and she suggested giving piriton for rash and monitor it. Anyone got any suggestions? Thanks
