Here are some things to consider:
* Her feelings: The most important factor is how she feels about her leg hair. If it bothers her, she might want to shave. If she's happy with it, she doesn't have to.
* Safety: Shaving can be safe, but it's important to teach her how to do it properly to avoid cuts and ingrown hairs.
* Body image: It's crucial to talk to her about body image and encourage her to feel comfortable in her own skin. Shaving shouldn't be about conforming to societal expectations.
Ultimately, it's a decision she should make with the guidance and support of her parents or guardians.
