Cool, Cindy. Please just be aware that if your daughter fasts for longer than 5 days it will dramatically change her metabolism and you could be inadvertently setting her up for major weight problems in the future (this happened to me when I was 17 and used a liquid diet fasting program for 3 weeks - I didn't lose one pound, in spite of not cheating, and have had weight problems ever since). Any kind of fasting (no matter the goal) will change the metabolism of a child still in the growth stage.
I do believe in cleansing (even for the very young), but be aware that a raw foods diet can safely be used to cleanse without disturbing the metabolism. I just want to encourage you to be careful, that's all. :^)
