I just want to point out that "narrow hips" have nothing to do with whether a baby can fit. What matters is the pelvic inlet- i.e. what you can't see... that, and the baby.
AND, the CPD thing is bs IMO. I don't believe that a mom would make a baby who doesn't fit-- however, often babies are malpositioned and so they don't come out well because of that. Something as little as having a deflexed head increases the diameter of the baby's head by 1.5 cm.... a lot when it's generally a tight squeeze either way.
I have very narrow hips on the outside but have successfully pushed out 2 babies and will do it again this coming January
