I recommend you keep accurate records (a calendar, copies of all medical records, copies of all Dr. visits, reasons for any missed appointments). Speak with your own personal pediatric doctor and follow their medical advice. You should keep these records to show that you are taking care of the child appropriately in case there is ever any legal issue.
Unfortunately, I can't think of anything you can do to stop the doctors from treating you this way other than changing care providers. I would caution you not to do this without having a doctor of your own willing to back the decision.
