I trooped to the swimming pool today with 9 month old DD2 (having clearly forgotten since the first time around how much hassle it is to take a baby for a paddle) and in the baby pool splashing about is a boy of maybe 2 or 3 with full blown chickenpox, bright red spots that didn't look at all scabbed over.
I said 'Excuse me, hope you don't mind me asking, but is your son still at the contagious stage?' to which his mum says 'Oh no, not for AGES' , but she then proceeds to bellow at him to come away every time he goes anywhere near another child or either of the two pregnant women sat there with their babies, which makes me think this was a blatant lie. You are still a bit contagious in the early, very spotty stage, no?
Now, DD1 has had CP, and I am not precious about DD2 getting it as they all will sooner or later, but there's a difference between that and deliberately putting them in a situation where you are exposing them to CP.
I also know how hard it is when you are trying to entertain an obviously boisterous child who, despite the spots, feels well in themselves - but surely, if you knew that there was a chance your child could pass it on then you'd just get the Aquadraw and a few jigsaws out and make them run laps of the house, and keep them out of the way of other children for a bit? Or AIBU?
