That's the problem with one-size-fits-all methods. Kids are just different and what worked for one child doesn't necessarily work for another child. Even if you do exactly the same thing.
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.
