Re: My first c-section - so many questions!
Just a suggestion but why not let your body go into labor naturally. That will give baby the longest amount of time possible to turn. If the hospital has an OB on staff all the time then there is no reason you wouldn't be able to do this. I would also insist on an u/s before surgery to make sure that baby is still breech.
I think the probiotic suggestion of the previous posters is an excellent idea. You should probably even start taking them 2 weeks or so before your due date just in case of a c-section.
Best of luck to you Mama.
