4 days ago DS1 came out in chicken pox, they are still spotty and haven’t scabbed over yet. For Xmas day my parents are supposed to be travelling to us. They are both in their 70s. I have told them about DS and the fact that my youngest child is likley to be infectious with it even if not yet spotty. They are adamant they had chickenpox as children and so are still coming. I don’t think it’s a great idea. WIBU to make them stay away even if they really want to come?
