Research by Zhang and others suggests that the Friedman curve has not kept up with the times. Far more women are getting epidurals, and they're putting on more pounds than ever during pregnancy -- both factors that can slow labor.
"Mother's weight has a direct effect on baby size," Zhang says. "The babies are getting bigger. That's not just in the U.S., but also in other countries. The bigger baby not only means slower labor, but also a higher C-section rate. The question is, how much is that due to the big baby, or how much is due to the expectation that labor is supposed to go fast, but it didn't?"
Catherine Spong, head of perinatology research at the National Institute of Child Health and Human Development, says she learned a valuable lesson while training to be an OB/GYN: "If you were patient enough, most babies could come out vaginally."
