Excerpt:
"Assumption: Elective C-sections for big baby has benefits that outweigh the potential harms. Reality: Among women who are not diabetic, it would take nearly 3,700 unnecessary C-sections to prevent one baby from having a permanent nerve injury due to shoulder dystocia. If care providers recommend an elective C-section for extra big babies (>9 lbs 15 oz), for every 3 cases of permanent nerve injury that they would prevent, there would be 1 extra maternal death."
