Then I suggest you skip the pediatrician and go straight to a psychologist or behavioral specialist. My son's General pediatrician tried to say the same thing. He wasn't in the psychologist office for 5 minutes and the doctor could already pinpoint what his problem was. My son defies everything told to him. Whether it's me, teachers, it does not matter who it is is natural instinct is to defy. That's what odd is. It's not a disorder you're born with it's a disorder you acquire in early childhood. Usually due to trauma or stress. My son's father leaving him high and dry is the creator of my son's odd.
