"After being completely pain free, I lost my ability to focus and felt the strong contractions for the first time -- very, very painful," said Parr. But she still credits the method with her "healthy, beautiful 9-pounder."
"She is a totally easygoing, loving, caring, peaceful and sweet little girl," she said. "I think HypnoBirthing helped with this."
Mongan advises expectant mothers to choose care providers who are "supportive, but not an interventionist," be it a doctor or midwife. "It's important they are in sync with the philosophy of the birth."
Even though women like Susan Parr ended up with a C-section, Mongan says not to worry. Only 16 percent of HypnoBirthers undergo that procedure, compared to the national average of 33 percent.
"Just say, 'I will accept whatever turn my labor takes," she said. "We are not opposed to intervention, but unnecessary intervention."
"About 70 percent of our women who birth do it naturally, without medication," said Mongan, who is also not opposed to using painkillers, if a woman wants them.
"We believe that women need to reclaim their birth in whatever way they choose," she said. "The last thing we want to see is a woman biting her lip."
