I would also try chiropractic - the webster technique. While it didn't work for Liam, it felt wonderful! Also, there is the "peas on the head, soft music on the pelvis" technique, handstands in the pool technique, and of course, my favorite, moxibustion. I found moxibustion extremely odd. Your mileage may vary.

I totally get you not wanting to try a vaginal breech, despite me having an extremely good experience with it. I would say to weigh the options carefully in terms of when to go for a c-section if that is how it ends up - a friend of mine was all prepped for a c-section due to breech presentation when they did a last minute ultrasound, and found baby was head down, fully engaged (i.e. wasn't going to move again). She was really pressured by her OB and the nurses to "go ahead and get the baby out" even though there was no longer a good reason.

And some now feel that the trial of labor is helpful for the baby, even with the result being a c-section. at least you will know that the baby isn't artificially premature if labor has started. Most OBs want to schedule it, though, and will press you hard to not go into labor before the section.

I hope you don't have to face these decisions at all - sending niblet turning vibes!!!
