Belief in healers can override needed medical care for children

Evidence

My daughter is five years old. She had heart surgery when she was a baby, and she has to have annual checkups. My ex-girlfriend canceled the appointment this year. She stated at the hospital that she will go to another clinic. In truth, she is going to a healer who assured her that he would cure her daughter and that already the first surgery had been unnecessary. My ex has sole custody, I don’t even get to see the medical records. — Holm Gero Hümmler, Ulrike Schiesser, Fact and Prejudice, 490
