Is the Freedman Curve Changing?

As c section rates went up in the country, there were various attempts to sort of look at why. Therecame a lot of discussion about maybe not all labors are quotanqut abnormal if they don't follow exactly the freedmen curve. And so we started looking at it again and thought, maybe things happen a little bit more slowly than we previously thought it. Maybe that active fave doesn't start for everybody at four centimeters. In fact, we think probably now it's closer to six centimeters or so for most people, yes.
