I don't see why moms need to criticize how babies are born. That's just weird!
The only pet peeve I have in regards to birth is unneeded early induction, unsafe medications, and doctors not regarding the interests of the mother. Birth is not meant to be 'convenient' for the doctor. It should be entirely on the mother's terms and a doctor should be honest with their patients! I feel like they often lie just to get you out of the hospital and don't give you or the baby any time.
Unneeded early induction gets me, too. When my SIL was pregnant with my niece, she was induced on her due date, just because she was "ready to not be pregnant anymore". I understand that it's really uncomfortable to have 6-10lbs of baby inside of you, but I would have given anything to get to that point.
I obviously understand induction for medical reasons, it's just "I'm done being pregnant" that irks me.
