"They told me they were reluctant to attempt a breech delivery down an "untested birth canal"" moron. Utter moron.
I'd certainly go with your instincts on the ECV. Moxibustion is a great option. You could check out www.spinningbabies.com
Sadly the art of supporting women to deliver their babies by the breech has dropped off following the Term Breech Trial, a deeply flawed trial which should have had some really useful information but instead incorrectly reported that breech babies did better when born by caesarian. So, it's a case of having the right people at the right time. An Independent Midwife with experience of breech may be a good option.
The main risk is not having the people with you who are experienced with breech presentation (which is simply a variation of normal), and who try to yank the baby out. As your service seems to have these, that's really positive. I use the term "breech birth" to refer to a baby whose mother remains in control of the baby's birth (usually important), and "breech delivery" to refer to a birth where the caregiver attempts to extract the baby without clinical need. It would be worthwhile discussing this to find out whether your caregivers are "hands of the breech" style. This article explains it very well, by the absolutely amazing Mary Cronk: www.aims.org.uk/Journal/Vol10No3/handOffbreech.htm
This is also useful although it was written before the Term Breech Trial came out www.aims.org.uk/Journal/Vol10No3/breechCSvsNormal.htm
One final thing, almost all babies benefit from going into natural labour first even if they're born by caesarian. It means they're not being inadvertently delivered early, and they are as ready as they're going to be. There are other chemical reasons too. But that's very personal choice as you may prefer to avoid what would be classed as an EMCS if you were in labour, even if you'd planned a caesarian birth.
Oh, and check out delayed cord clamping and you might want to talk to your caregivers about resucitation with the cord attached, if it's needed, and a few more breech babies do than head first babies. It should be possible and it means that your baby will still be getting some oxygen through the cord which is obviously a good thing.
So that's your Googling done for you and here's a fabulous book (check with your local NCT group, they may have it in their branch library): www.aims.org.uk/pubs.htm#breech Good luck with your decisions, remember that breech is a variation of normal and you can do this, whatever you choose xxx
