DD (my 1st) was born as a breech baby at home with IMs. It was a decision we thought long and hard about and not one we took lightly, but for us it seemed the right way to go.
"Breech Birth" by Benna Waites and "Breech Birth: What are my options" by Jane Evans are both very informative. As is most things written by Mary Cronk that come up with google.
One of the things that drove our decision was that the research used to promote CS for breech babies is very badly flawed - to the point most of the authors agree it should be discounted. More recent studies found that, as long as you have the right risk profile and HCPs experienced in breech birth, vaginal birth is slightly safer than CS for breech babies.
Everything we found seemed to back this view up - vaginal breech birth isn't intrinsically dangerous (c/w a CS). Vaginal breech birth with a MW or Dr who doesn't know what they're doing is.
Once we'd decided to use IMs and were comfortable with that decision we were happy to decline an ECV and decline a CS - you don't have either procedure. Even though DD managed to turn into a footling breech and weighed in a 9lb 12, I probably had one of the calmest and most peacful births of anyone I know. The MWs were very much of the Mary Cronk school of breech birth ("hands off the breech"!) rather than the more medicalised model that hospital Drs are likely to be familiar with. If it had been a choice between a medically managed breech birth (on my back, in stirrups, in theatre, cast of thousands, episiotomy, forceps) I'd have been booking the CS like a shot. Incidentally, if you want to know what your options really are within the NHS its worth reading up on different types of vaginal breech birth and talking about it with the head of midwifery - some PCTs still have clusters of MWs with very good breech birth skills, they just may not advertise them.
We didn't talk to IMs till I was about 34 weeks, and didn't sign up till 36 weeks. We still got two lovely ladies that we gelled with very well who had a lot of breech experience - if its a course of action you're interested in its worth talking to them. If money's a concern they can be very flexible on payment (many will happily take payment in kind or work out installment plans), and most will be more than happy to offer general advice on what your options are without being bound to follow the NHS party line.
How to bring a breech baby into the world is only an easy decision if you're prepared to follow the policy of your PCT without asking too many questions (which usually means having an ECV and/or a CS). Otherwise its incredibly difficult - none of the options are risk free and you can only make the best choice for you and your family at the time, based on the resources availble to you.
