I don't have a daughter, I have a son, but if he were to become a teenage father, I know that I would love him unconditionally no matter what. I believe I would react the same way if I had a daughter. I have no qualms admitting that I am pro-life and would do whatever I could do prevent an abortion. I honestly think it is wrong to think someone's life is over because they have a child at 16. I guess I just don't think a career, money, traveling, etc is more important than a child's life (talking about the baby here). Not to mention, having a baby DOES NOT guarantee that all of the rest of that stuff is impossible. That being said, if my son's girlfriend/hypothetical daughter chose that option, I would still love and support them.
I really would, however, encourage either keeping the child or putting it up for adoption. Even if that meant that I had to do much of the "raising" of the child, I would do it.
I myself became pregnant out of wedlock, and though not a teen, have actually been told on these boards that I should have aborted him because he was not "planned" and I was not 100% sure I even wanted children. Sometimes I think we are much too quick to jump on the easy-way-out abortion choice. To me, abortion was never an option. And I honestly cannot imagine my life without this little boy:
