In general, there is a fairly "normal distribution" of the amount of crying and moaning that occurs during labor and delivery. As you might expect, some women are fairly stoic, while others are more animated and show more pain. I find it hard to be judgemental of any of these women. I'll never know what it feels like to deliver a baby, but I imagine it as something akin to a bowling ball coming through a very tender part of your body, so I don't blame women for showing some pain. I really don't know how I would be if I were delivering a baby.
Every now and then, though, we get a woman like the one described above, whose response to pain is far beyond the norm, who totally loses control and goes absolutely bonkers. They move around on the bed, they close their legs, they don't push; they are very difficult to care for, and their lack of control just makes it worse for them. I like to think that I wouldn't be like that if having a baby, but who knows?
It didn't help that this woman's obstetrician, who happened to be a woman, was screaming right back at her. It was almost comical to see the two of them yelling and carrying on, although the situation was a little serious for anyone to be laughing. There aren't any easy ways to make a person who's "lost it" get it back, but I really think that calm explanations and instructions have got to be better than shouting at her.
Finally the woman delivered, in spite of herself, and things calmed down. Labor and delivery can be a crazy place, and the people even crazier.
