Hugs BeanBean! I hope that some suggestions are given for encouraging a breech baby to turn. I can look some up for you, but I do not have any personal experience.
What I am dealing with is trying to avoid as many interventions as possible (including c-section) within the confines of the MFMs' set up. Maybe you can buy yourself some extra time incase she is still breech at 36 weeks... Talk to your drs. about leaving the stich in at 36 weeks but not scheduling the c-section for much later (41 wks though they may say no, then ask about 40 wks., then 39...) Push it back as far as you can and maybe argue that due to her small size you would like to give her a bit more time before surgery..... Not sure if that will work, but it may be worth a try. Have them monitor her positioning right up to the time of surgery and if she does turn then maybe they can remove the stich and proceed with a vaginal birth. Hopefully she will turn before 36 weeks so you don't have the stress of a surgery looming over you.
Also ask what kind of breech position she is in. Some breech positions are able to be delivered vaginally. Though I suspect that being "high risk", your drs are less likely to even entertain the idea of a breech baby being delivered vaginally. You could bring it up if you wanted to feel it out as an option or let them know that you are willing to explore all options before agreeing to a c-section.
Did your drs. offer any advice for encouraging baby to turn? How about your mfm nurse? (My nurse is sooooo supportive and open to helping me any way she can, as opposed to the drs, that just want to stick to their normal one size fits all routine, regardless of my particular situation.)
Remember to breathe!
Oh! check out the "transverse anyone?" thread. Just saw that spinningbabies website was mentioned and there was another mama there with a breech baby working on getting baby into optimal position.
