I didn't think about it before today and maybe because I'm really watching him and his behaviors since he's been shadowing me, but when a person asks about head banging, I've always answered no ~ when I think head banging, I think of it as an all the time thing and a child walking around with- bumps. But today when he put his nose on the wall for innappropriate behavior, he banged his head on the wall several times. Thinking back, he's done this before, but it wasn't what I would have called head banging in the sense I assumed. Is this something I should be answering yes to? Someone posted a childbrain test link so I took it ~ it came out with- a score of 144 Moderate Pervasive Developmental Disorder (PDD) for difficult child. I've seen Autism Spectrum Disorders (ASD) symptoms for several years and the therapist agrees, but through his testing at the university they said no.
