I homebirthed 4 of my 5 children. My only tramatic birth was the one that ended in a transfer (baby turned brech during my labour) and subsequent c/s.
I actually have met very few homebirthers IRL, and none of them have ever expressed anything other than satisfaction with their birthing choices. I don't know any other people IRL who have needed to transfer either.
Therefore, I am one of those who has to vote about how wonderful it is and how I often bore people silly with my stories of the same.
Maybe h/ber's are more aware of the birth process and the fact that it will be hard work, so see less trauma in the situation than other's might preceive?? Don't know myself, just guessing....
