Welcome, Korrie. Just saying hi in passing on a very busy morning (my time down under).
You really have your hands full! You've found a great place for support and information. Browse around the archives and other forums while you're waiting for people to get back to you.
I do have a question for you to ponder - has there been a thorough evaluation done yet? At this stage you have a list of what are basically sub-sets of a number os possible disorders. Sensory Integration Disorder (SID) and ADHD-like stuff often goes hand in hand with other conditions such as Pervasive Developmental Disorder (PDD), for example.
Right now in our house, we're dealing with Obsessive Compulsive Disorder (OCD), ADHD, ADD, ODD, Sensory Integration Disorder (SID) and other stuff, all coming under the umbrella of Pervasive Developmental Disorder (PDD) in its various forms, in three of my four kids. The broader label has helped me understand better.
Anyway, welcome. Stick around!
