My son displayed full blown symptoms at 3, 4, 5, and 6 but I would not allow any medications and handled it through diet, relaxation techniques, and a very structured schedule with consistancy, consistancy, and more consistancy. When he was 4 1/2 yrs old
, I took him in
consultation at the request of his pediatrician. I was instructed my the doctor to allow my son to roam freely throughout the room so that he could observe what he actually was doing.
