Roseola

Seamus started getting a rash yesterday(Sunday) and we weren't sure if it was heat rash or something else. We first noticed it around 2pm it was small just around his shoulder/neck(where they meet), I then notice it spread down his chest a little and under his neck and slowly to the back of his neck. We got him some cool drinks and a cool room and it didn't go away, so off to the doctors we went. Hes got Roseola. It will go away on its own but we need to watch Kieran now, and subconsciously I'm itching even though hes not...uggg
