I raised for children, and supervised many groups from cub scouts, boy scouts, church groups, sports teams,......
That gave me much better training than my degree in psychology. My wife is an MD psychiatrist, thus I am well aware of the neuro-biochemical changes that influence mental health.
I’ve worked with many adopted children who act out at age 8 to 12. This is usually created by a fear of rejection and low self image due to birth parent rejection.
Very few health professionals know how to resolve the root problem in the consciousness programming. These adopted children, even when raised by excellent parents, can be Nobel Prize winners or Olympic Medalists and still not feel “Good enough.”
As one who obviously has a great deal of education in the psychological field, I would have thought you to think your training gave you great insight into child mental issues - kudos for not being full of yourself. Very few people, particularly the more educated in these fields, are keenly aware of the differing needs of deep disorders that defy textbook definitions. You could no more walk into my house and know how to deal with my child as I would have no clue right off to understand another’s child even with the identical diagnosis.
