My 7 old son is showing some signs of ocd, counting ,tapping, and if he bumps something he might go back and bump/tap it again. His new thing is that he hit himself in the head and when i asked why he did it, he aays that he likes it. Tonight he took my hand and tried to get me to hit him in the head. I told him that i wouldn't do it and he said he likes it. I am freaked out. I have an appointment with a clinician but its a couple weeks away.
