I know a source of chicken pox, and I would really like to have my three-year-old exposed to it. I also have a 14 month old. Do you think she is too young to get the chicken pox? I am really having a hard time deciding on this. I don't want to miss my chance for my 3 y.o. to get it, especially from someone that I know, but I don't know how hard it will be on my little one. Any thoughts? Advice?
