I don't agree with that.
okay.,.. maybe 1% of the time, a 16-year old gets preggo and her parents were on top of things.
but the other 99% of the time, it's the same thing... they let the boyfriend stay over... they let the kids drink... the parents weren't there much of the time... etc etc.
hell, you can look on your kids computer or myspace and learn a ton about them these days. Or, you can just sit and talk with them.
I have known a lot of teenage moms, and in every case, it was always the same. parents let the circumstances happen and one thing just led to another. it's trashy. Limits much of the kid's options for life... having a child that young makes school/work MUCH harder... and the boy she's dating at 16 is very rarely the kind of man she'll want at age 25 when she's established her career and education.
So yeah, 99% of the time, trashy parents let their kids run wild and lots of sex = teenage mother.
EDIT
I dunno... A kid has no business f---king... it's that simple. Wait until you're 18 and out of the house. Teach them what options are limited if they have a baby before they're a senior in high school. Maybe it's perfect parenting and trashy kids, just fcking without condoms because they're idiots. But 99% of the time, parents hold blame too.
