7 Year old with PDD and aggressive behavior

[Guest guest]

I have this book I've been reading called " The Bipolar Child " . My son

has never been diagnosed this. His most recent diagnosis is PDD.

We've been having such problems with him at school. Hitting and using

bad language mostly. Nothing that the teachers/behaviorist seem to

try works with him. Is this typical of kids with PDD? I'm thinking

it's more than that...more like a mood disorder. He will have a few

great hours and then out of the blue just hit his teacher for no

apparent reason. I'm just trying to get info. so if anyone could

relate to anything that has to do with this subject please let me

know. I know there's lots more to Bipolar and all these disorders I'm

just trying to sort it all out. Thank you so much. We have an appt.

with the psychiatrist Mon. night and I'd like to gather all my info.
