6 year old male, inappropriate urination in forbidden places, defiant, stubborn and argumentative at times but otherwise very sweet child. Has never eaten enough to even speak of. Is on Vivanse (for adhd) and has also started with forced eye movements and odd movements (twitches) of his head. Discipline in the past has consisted of parents having reached their limit and been somewhat extremely loud and vocal with him which only infuriates him and the 'match is on'. What is going on? All parties involved need some help and advise before this continues much longer. Thank you.
