Ethan and Elodie both had it back in May/June. Elodie had it alot worse than Ethan, I expect because she was exposed to it for longer as Ethan had it first.
I'd rather let them catch it randomly than trying to catch it on purpose. Chicken pox isn't any fun for you or them. We were stuck at home for almost five weeks and Elodie has alot of scars
