Delivering off your back?

Abby • Full house, full hands, full heart! 4 kiddos 9, 7, 4, 1 and #5 on the way. 3 angel babies.

Has anyone ever delivered in a position other than on your back? I would like to deliver like this picture. My dr says it’s fine as long as I’m on the bed because she said the baby is too slippery to deliver in any other location.
