Oh, dear. This sounds like a very dangerous situation that must be addressed. First of all, have her watch shows like 16 and pregnant and Teen Mom to show her the true reality of being a young mother. Remind her that sex is for married couples only and is a convenant with God, and that pre-marital intercourse is extremely sinful. Show her the dangers that come with unprotected sex, including STD's (which can be fatal) and pregnancy. Also, point out that because she isn't legally allowed to hold a job, becoming a mom would be a disaster for her and the baby. She would be waking up at 3 am to a screaming child while her friends were out at parties. And may I point out that if she can't get a job, chances are she'll dump that baby on you. If she does get pregnant, (heaven forbid), make it very clear that abortion is not an option because it means killing an innocent baby.Let her live the remainder of her childhood. Today's media gives an overly-sexualized depiction of teen girls, and you should remind her that she is a unique human being, not a sex object.
