Try having an ADD 2yr old empty a bottle of Wesson oil all over your kitchen & family room.
He wasn't diagnosed with ADD until he was entering 3rd grade & his teacher requested a conference. She only confirmed what I'd been telling my dh for yrs. He still wasn't convinced until our son was examined by a well-respected pediatric neurologist who prescribed Ritalin. That med got the kid through the next 20yrs of his education. (B.S., UVa; PhD, JHU).
That pediatric neurologist, btw, was Dr. Ralph Northam, current governor of Virginia!
Sometimes we just need some chemical intervention.
