Stay involved in your teen's social media usage and monitor her accounts. You don't have to snoop around. Be honest with her and explain that when she sets up her Facebook account, you will have full access to make sure she's safe. Create your own Facebook page, if you don't already have one, so you can be Facebook friends with your teen. That doesn't mean you have to flood her Facebook page with your comments or become friends with all of her friends. It's just a way for you to keep tabs on what is happening on her Facebook.
