Below is an excerpt from When A Big Baby Isn't So Big
"The new study, called Listening to Mothers III, was based on Childbirth Connection’s nationally representative survey of some 1,960 new mothers. It found that four out of five of the mothers who were warned they might have large babies gave birth to infants who were not large, and weighed less than 8 pounds 13 ounces.
Yet these mothers were almost twice as likely to have medical interventions such as having doctors medically induce their labor or attempting to self-induce labor, presumably out of concern the baby would continue growing otherwise. They were also nearly twice as likely as other mothers to have a planned cesarean, though the increase fell just short of being statistically meaningful."
