My DD is 20 months. She goes once a week to a music class that she absolutely loves. Today one of the kids was ther pale and had the pox starting to spread across his face. I asked the mom politely and she goes “oh yes, both of my kids have it. It’s not that serious.” I internally screamed “no you daft bat, it is serious!!!” I mentioned it to staff, who have now emailed all parents on the roster that there was an exposure (I’m assuming after confirming with her, email did not say which child). We called DD doctor and they have her coming later for CP vaccine. AIBU to be absolutely livid?
