I would like to have a free birth one day. I've had two cesareans and have absolutely no fear about doing it unattended. I'm more afraid of having another posterior baby!!
I am lucky to have an exceptional vbac midwife nearby who I may contact for prenatal care and then decide in labour if I want anyone around for the birth.
So, no, you are not alone or crazy for thinking about it. I love the idea of unassisted birth and hope that I may experience the freedom of it one day.
