@disclosingshite I wish you would. I'd make a conscious decision never to be around you or your children.
I cannot get rubella immunity. I have had the vaccine twice. It never gives me immunity. If I were to catch it from your unvaccinated child, yes it would be your fault if my unborn baby was damaged because I've done everything I can to make sure I am immune and because of selfish people like you I'm put at a greater risk.
What if your sister or best friend or DD's nursery teacher was like me? As you say, why would you discuss it? Would you be able to look someone you cared for in the face and say 'I know you couldn't do anything about protecting yourself more, soz about your damaged baby but my kid is fine so...'
