Hi, my 6.5 months has got what I'm 100% sure is chicken pox. Started with what looked like a rash 3 days ago and then pimples. Now has them on her arms, legs, back etc... Has anyone else's baby had chicken pox so young? And how long did it last? I have a 2 year old and haven't noticed any spots on him yet but he did have a temp a few days ago that only lasted an evening after giving him calpol. Is it possible to have mild cases that could go unnoticed? Typical that we're meant to be going way at the weekend.
