The sad thing is... that is becoming more and more common these days. I watch girls lose their childhoods all the time. If you're 20-21, I can see it being a little more okay but at 15-16, you're still a kid. It's really sad sometimes.
My boyfriend's step-sister had her kid at 15 and the girl is now 7 and the poor girl never sees her mom because her mom spends most of her time out at the bars, basically anywhere with her boyfriend, and the little girl is shuffled from daycare, to babysitter, to grandparents, just because the mom wants to party. It's just so sad because she is such a sweet little girl.
