I applaud this. An incompetent doc wanted to put my 5 year-old through a blood draw simply because of low BMI. I switched doctors and the new doctor gave the all clear based on physical examination and overall growth trend.
Doctors vary. The first pediatrician we used was teaching at a university. Every visit led to a battery of tests. Eventually we suspected the Dr./Prof. was financing their studies with our insurance. I don’t think we have a single blood draw since we changed Dr.s.
