Modern medicine is great, but sadly they push C-sections a lot. My understanding is they can bill at least 50% more than a natural birth. This skews even higher if you don't have the best insurance.

Also once you have one c-Section, the chances of a second increase significantly. It is not suggested to have more than two c-Sections, so if you want three kids you are out of luck.
