Why do some women push for a few mins and other push for hours?

mu

I have always wondered this. About to have my third baby and with my previous 2 I pushed for under 10 mins.

I can’t imagine that lasting for HOURS oh my gosh.

A nurse once told me I had a “roomy pelvis” whatever that means so maybe that’s why I push fast? That’s not always a good thing because The pushing stage to my firstborn was so fast there were some complications such as him still having fluid in the lungs. The act of pushing is supposed to expel that I guess.

I’m just so curious because the only answer I’ve found is that it depends on your bone structure or something.
