DD age 3 has come up in some kind of rash/skin reddening on her arms and legs. It's not a spotty or bumpy rash - flat skin but a spotty and red effect. It started on her forearms a couple of days ago and is now covering her lower legs and going up her thighs too.
She doesn't have a temperature and is not showing any signs of illness.
I'm guessing it's some kind of allergy/reaction to something she's been in contact with but just wanted to rule out anything serious!
