Sounds like the law of unintended consequences unleashed.
I worry that my dd3, who is 10, has never had chicken pox, but would never follow the advice I am always being given to deliberately expose her so she gets it while still a child.
What has worried me is that she could get a particularly nasty bout (you can never tell how strongly it is going to hit - ds got it off dd2 and while she had been fine he was really ill). I would never forgive myself if I had exposed her deliberately and she was really ill (or even got a secondary infection).
YANBU and have given me another reason to avoid doing this myself.
