DD11 was exposed to them at the age of 9 months when my mom put DD and DN (both under the age of a year) in the bath tub together. She didn't know at the time, The next day DN has spots all over!! It was a sleepover!!
Well DD never got them, we were so nervous becasue withen 5 days of her being exposed we were going on vacation!!

We took her to the doctor because at the time we were 1st time parents and nerotic!

Well 2 years later she was exposed again, DA babysat and she also ended up having chicken pox 2 days later. Again we were nervous ,she had sniffle, we took her to the DR again. Dr stated she must have a natural immunity to chicken pox. Over the years she has touched, played, even shared the same phone w/ people who have had Chicken pox and never has had them.
At this age in her life I wish she would just have gotten them when she was older because I have heard that the older you get the worse it is.
Our Dr. never gave her the immunazation for Chicken Pox because at the time her DR said she was better off getting them and getting the immunazation would not prevent her from getting them she would just get a milder case of them.
We're going in Sept. and now all I can think of, after reading this thread, she will get them a day before we leave.
