I commend you on your decision to refrain from vaccinating. Don't give in to the pressure from some of the people on this board. Message boards are a great way to spread ignorance. You must take each opinion with a grain of salt, but always stick to your guns. Only you know what's best for your child.
Second, while I do not know of anyone with chicken pox, you could always have your kid play with someone who just got the shot. According to moms who don't vaccinate, the just-vaccinated children are the ones to get the illnesses from. I thought that was a pretty interesting tidbit of info...
Also, before exposing your child to CP, make sure she has a healthy strong immune system, to make it easier to fight off and prevent complications. A healthy child fights off the illness and ends up with lifetime immunity. A vaccinated child does not. But you probably already knew that or you wouldn't be asking this question in the first place.
But good luck!
