Funny, I almost went into Obsterics but I have notoriously unsteady hands however I love the study of the female body.
Here's the thing about c-sections..you have doctors who make really bad decisions doing those procedures. It's VERY EASY to make a mistake fast with a small lapse in focus..you got doctors who're druggies and alcoholics recommending surgery for delivery for selfish means when they can't keep their hands steady to even wipe their own asses.
It's VERY easy to cause damage to the intestines, the uterus and surrounding organs with c sections. The worse part is that women really don't have recourse when these doctors get careless. I'm pretty sure that you got ileus from the procedure you had with your firstborn.

But wait....its been almost 8 years. I'm sure at this point there would be no way for anyone to prove that without doubt.
