This is such a sticky situation. I like the idea of a girl's day. Just make sure to let her know how much of a problem this is and was for you. My 18 year old knows I "used to" SI and her best friend cuts. She decided it was okay to try if it made her mom and her friend felt better afterwards. I guess neither of us impressed upon her how dangerous it can be after all. Luckily she couldn't stop the bleeding, and got scared. Plus she said it hurt! No kidding.
