DD has had symptoms of H,F&M since Thursday, "ulcers" came out Saturday. She has been so unwell with it the poor little thing. The thing I am wondering though is will DS get it? He had it when he was just under 1. So I am thinking that if he were to get it, he should have got it by now? Do you know if they build up an "immunity" to this sort of thing, hence why he hasn't got it again or should I still keep him away from other kids too?
