This is a classic epidural outcome. This is why the c-section rate is way too high in America. We have the worst stats in the Western world for labor/delivery. There's nothing anyone can do at this point, so really, it isn't worth discussing at this moment. Of course, if your SIL gives birth in the future, it would be helpful to know this info. But then again, most docs today do not allow a woman to deliver vaginally after a C-section anyway. I highly recommend the book, The Thinking Woman's Guide to a Better Birth by Henci Goer. Lots of research involved. About half of the book is her bibliography and references for what she writes.
