Is your daughter asking your permission to shave her legs? The reason I am asking is because when I was 12 years old I actually asked my mom if I could shave my legs. She told me that if I was responsible enough to ask then I am responsible enough to do it and she just told me to be careful. I had light blonde hair on my legs but it was very thick. If it makes you feel better try letting her use an electric razor instead of regular razor until she gets used to shaving and a little older.
