This is how Dr Han Dong-up, who works at a Christian hospital in Korea, has described the bonding benefits of vaginal birth, in an article criticizing the high rate (36.8%) of Korean women choosing c-section births:
"We persuade the mothers to endure the pain and see the baby in a more natural state."
"The more painful the whole experience was, the more attached you would feel to the child," he said.
This point of view has been around for centuries, and as anyone who knows their birth history, pain relief in labor (from chloroform through to modern epidurals) has been frowned upon by many health professionals for being "unnecessary".
Perhaps it's only natural that the criticism would extend to prophylactic cesareans too.
