I told my DD who is 7months older then your DD she can wax her legs as soon as she is ready. As I don't want to run her of to the beautician every 6weeks Ill do it myself (I've done my own for years) and it will be so much cheaper this way. I wish my mother made us wax not shave. I figure when she is ready she will want the hair of so much she wont care about a little discomfort. At the moment she is happy with her hairy legs but it is blond and fine. When I do mine she occassionals says can I do one strip for her which I do and it doesn't really bother her although she doesn't come back for more lol well not until the next 6weeks when I am doing them again.

Foils sound nice. The school my daughter goes to doesn't allow anythinkg like that so it wouldn't be an option for my DD until she was in high school. If your happy and she wants them I don't see why to wait.
