​Psychologist with M.D. aka The Pill Pusher- Once Custody is established that is not favorable to your wife or she just wants to change it, and the counselor thing is not working, she must up her game a bit and further destroy her child to get the favorable custody she desires. If the kid is behaving like a kid does, the mom will often take the child to a Psychologist who will spend little to no time with the kid and put them on medication for anxiety with doses being upped on a whim at the request of the parent to create more problems so the custody issue can be revisited. 

People can certainly have different views about whether medication is appropriate for children, but it is often too easily used as a crutch to control kids or devalue them in a spiteful way against another parent. Too many normal kids who experience the growing pains of life are being put on medication with little or no justification medically or at the insistence of a parent who either cannot or will not involve themselves are parents in their kids lives. Kids need our help in preventing them from the damage unnecessary medication can cause. Don't ignore you ex wife's desire to use a pill pushing M.D. to her advantage and as a man and father you have a duty to your child to learn as much as possible before allowing this to happen.
