My girlfriend used to train dogs for a living. She always said "it's the owner's fault, not the dog's". Now we have a Chihuahua who won't listen, doesn't respond to rewards, doesn't respond to punishment. She just does her own thing. My girlfriend is much more humble now. I wish a lot of these child psychologists would have to deal with a difficult child day in and day out, not just once a week. Maybe they would also lose some of the confidence in their advice.
