I'm happy that you have asked me to assist you with your child and hope that you can benefit from my many years of helping parents like you.
The Pavlik harness is not painful or an "ordeal" for the baby I assure you. One of my granddaughters wore one for most of the first year and did great.
The issue is that not treating congenital hip dislocation can lead to serious problems later on with the development of the hip joint and then may require surgery to repair, which certainly is painful and an ordeal I assure you.
The radiologist reads the hip X-rays and sonograms and can make the diagnosis but I agree that an orthopedist needs to see her eventually but treatment must begin NOW.
