After two cesarean sections, Rinat Dray wanted to give birth naturally. But when she arrived at Staten Island University Hospital in labor, the doctor immediately began pressuring her, she said, to have a C-section. The doctor told her the baby would be in peril and her uterus would rupture if she did not; he told her that she would be committing the equivalent of child abuse and that her baby would be taken away from her, she said in an interview this week. After several hours of trying to deliver vaginally and arguing with the doctors, Mrs. Dray was wheeled to an operating room, where her baby was delivered surgically.
