My daughter just turned 10. NOw she is asking to shave her legs!

I knew this day was coming.

She has a lot of hair on her legs and she is going into the 5th grade and I really don't want her teased. The hair is blond but you can still see it! I tried to tell that once you start you can't stop. She doesn't seem to mind it. She isn't boy crazy and she is very conservative.
She also has dome dark hair on her lip and she has gotten teased about that before. That I can bleach and it will look ok.. I hope

. I just wanted some opinions. Is 10 too young to shave?
