The one thing that always really bothers me about baby!fic is that there are hardly ever any options even talked about except keeping the baby. Abortion is never done and only rarely given lipservice at all. Despite the fact that the characters often have good reason to consider *ALL* their options. Not to mention the fact that it's totally outside of reality. 1 in 4 women will have at least one abortion in their lives, though you'd never know that reading most fic.
Though I do think that quite a few fics and authors write babies and kids fairly accurately in their stories. I've read lots of fics where having a baby or kid changes not only the characters outlooks, but lives. And they show the hard parts of parenting like exhaustion, changing one's life and priorities, discipline, safety etc.
But I mainly want more reproductive choices presented in fic. I work for Planned Parenthood and won't even pretend like I don't know more about this stuff than most, but because of it I am easily annoyed when I see so many options not even being considered because of what I feel is a value judgment of the author despite how impractical or unrealistic it is in the context of the story. Er, </rant.
