A friend on mine in the late 90s gave birth this way at home.
She said it was nearly effortless and should always be encouraged.
Did she have a midwife or nurse with her in case things went wrong?
I had a friend who had her last child at home in bed, no drugs. She seemed to find it far preferable to the hospital setup - you can move around and find the position best for you.
I’ve never had a child, but putting a woman on her back in stirrups - largely to accommodate the doctors - always seemed very unnatural to me.
But yes- you must always have a knowledgeable professional there. In the old days, women and babies often died from unexpected complications. My grandmother nearly did.
