>>74909511Like with circumcision, people are too used to it and make excuses to not move on. The main argument being that if a woman does the delivery standing up she might fall or the baby might hit the ground (which can also happen the way we receive them right now) so it's dangerous to do that.
Some people actually developed a delivery chair and try to advocate we should stop making women deliver while laying down, but ultimately nobody in general cares enough to pay attention to that.
