Fiftysomething years ago after 36 hours of labor, my Mama was ready to give birth. Since the Dr. had not returned, the nurse held Mama's legs together for some time to prevent my grand entrance. When he finally arrived, he administered gas and rendered Mama unconscious to deliver me ~ that's how they rolled back in the 1950's. With all that interference, it's a wonder I do not have any dain bramage.
