My hubby and I had an unassisted homebirth of our twins. Our daughter was a footling breech and born vaginally with no problems.
My midwife had an older relative who was also a midwife who used to turn vertex babies into the breech position because it was considered easier on the mom back in those days! Sooooo, it just goes to show that opinions change.
Personally, I feel a non-invasive approach is best with breeches. I figure, there's a reason the baby is breech. We don't necessarily know what it is.
My daughter just wanted to show off, I think. She timed her birth perfectly with a train roaring by...plus, there were big spurts of blood and lots of yells on her part.
