Actually I do, being a dad and being right there in hospital for the whole enchilada. Did the natural childbirth thing, rooming in, breastfeeding only, and did all this at a local hospital in the south that had never seen anything before in its life. Made the front page of the local paper. They almost gave her a shot of Pitocin, routine, but we stopped that at the last second. Wouldn't let the doc clip the monitor to the kids scalp either during delivery, upon which he glared at us and asked, "Who's the doctor here?"
But then we did it all over 18 months later, same place, same doc. Shit can work. We're still married buds 40 years on.
You know YOUR experiences at the hospital where YOUR wife gave birth TWO times. Apparently heathy, easy, natural events. Not only is not every birth like that, but not every hospital or doctor like that, nor is every woman or every child.
Did your insurance cover the birth? Did you see an itemized bill?
When our oldest was born, we paid for ALL of it, down to the last piece of gauze. Itemized.
Our next child was born at a different hospital, covered by insurance. We only say our very tiny co-pay. I have no idea whether the actual delivery charges were the same or not. First time, we spent more time in the hospital, because of a minor complication (not predictable). Second time around, also a c- section, different doctor let us go home earlier than usual because no complications and it was my second child. Also a different doctor/different philosophy.
You may have been present for the deliveries if your children and been a good advocate for your wife and children, but you sure were not counting gauze packs. And there were zero complications, no need for any interventions, any one of which costs $$.
You know your rather ideal circumstance and let's face it, you didn't do one iota of the pushing.
