Slyder, I hope your DW DOES hesitate - 'without hesitation' is how many women get caught up in medical jargon for a procedure that has more benefits for the Ob than for anyone else. Hesitate, ask questions, THEN make your decision. If you take these three steps early on in the pregnancy you can mitigate being railroaded from your plan (whether the plan is for surgical or for physiological delivery, but particularly if the aim is for vaginal birth). Practicing this now will benefit your child.
Oh, and it's not just your baby - a baby's best chances are maintained if BOTH mother and baby are treated as a unit, not as separate entities. Separating them makes it easier for things to go awry. One affects the other. Oddly enough, by the logic of 'what's best for the baby' most people would forego a lot of interventions during labour that create the cascade leading to emergency c-sections.
Anyhoo, to answer the other question - yes, believe it or not, there are women who deal very well with their decision to terminate, just like the women who deal very well with the decision for elective c-section. That's my point. One group doesn't feel the need to take counselling for years to deal with the 'loss' because they didn't perceive loss, and one doesn't feel the need to debrief from birth trauma because they don't consider it 'trauma'. How can we judge either of them and say "but you should feel x and y"? I think this is what the author was saying - other people were imposing THEIR values on her and she didn't feel the need to take those values on. Good for her. Someone else might be swayed and feel sorrow or remorse later on, and that could only happen if they had only repressed those emotions at the time of the event.
I know that there are rape/incest victims who are quite conflicted about termination resulting from that kind of pregnancy - not liberated at all. Disempowered from the get go and are cornered by their own values and trauma rolled into one. And, tsk tsk, there are women who termiate knowing that pregnancy just isn't where they need to be at that time of their lives - not an easy thing to go through, but an easy enough decision to make. Odd world, huh?
