awww Good on you Tracey. You do know that your girls are gonna take their lead from you, so if you "sell" it to them that it is just a clean up and you are cool with it, they will accept it a lot better. I know it is hard and that was the one thing that I did when I told mine. Mine were younger, and it was not scary as I "sold" it to them that I was not too concerned and how cool would it be to have no hair when it was hot. (inside i was a mess).
Glad you are getting some benefit out of this site, I was involved in the working party prior to it being set up and it so great to hear that many women are getting a benefit from it.
Love Tanya
