Got a call from ds3's creche to say he had an "angry" red rash on his arms and legs. Dh collected him and I met him at home. By then his arms were fine but his legs looked as though they had been burnt and felt hot. Brought him to GP who wasn't sure but thought it might be slapped cheek. But his cheeks have not been red at all lately. He has no temperature at all and is otherwise fine. Anyone else had anything like this?
