Did you see this recent story in USA Today? Some doctors (and women) say women should be able to choose to have a c-section because it protects against incontinence later in life, but this article says that might not be true:

BTW, the article was written by Rita Rubin, who is also the author of What If I Have a C-Section?, which goes into more detail about the debate about vaginal births and incontinence. The book also does an excellent job of explaining the hows and whys of c-sections and what you can do to speed your recovery from one. It's on Amazon and in stores.
