I haven't seen the movie, but I know the story. I would have to agree... Stupid!
I think most teenagers have absolutely no clue how much is needed to care for a baby. They say "Aww cute, I want one" and put no thought into money/daycare/time caring for it/the
*exhaustion*. They expected their parents to basically raise the kid and pay for it for them. The attitude most take after wards is "I'm a kid, so let me go out and be a kid!" Well, you took the initiative to go get knocked-up, you thought you were mature enough to take care of it, so step-up. If you've never watched 16 & Pregnant... you should. Those girls will make you say "stupid, stupid, stupid!" all over again.
Although I do have to give credit to those good teen mommies out there

Accidents happen, and some really do give it there all.
