Hey T.,
In reviewing old emails, I re-read this. I've found a book that might offer you some fresh ideas and support. For other moms of children with behavioral challenges or developmental issues who are reading this post, you might also like to read this. The book is called "Autism, Aspergers, ADHD, ADD, ? - A Parent's Roadmap to Understanding and Support!". The author is Diane Drake Burns. The author emphasizes the need to be your child's advocate in all important issues, to take care of yourself and to build a support network, among other things. It is a great book!
This sounds like a pretty complicated situation. As the mom, you are the best one to judge what will work, but please consider seeking someone who specializes in behavior modification for kids with PDD and autism.
You will probably find the answer lies in a combination of a modified diet, certain medications and certain methods to help him learn more self-control.
Just because he has challenges does not mean you shouldn't expect him to grow to behave in a better manner. Remember, too, that this impacts the whole family, so make sure to keep the needs of all your children, your husband AND YOU at heart.
Hold it in your heart that he will improve and the situation will improve. Your loved ones will sense this and rise up to that expectation. Find ways that the family can have fun together. At the moment, it might need to be low key and simple (ex: shooting baskets outside, taking a walk, etc.), but this will build positive memories and a sense of connectedness for the family.
As your son grows, his hormones will change and that will impact what works for him. Be prepared to keep searching, reading, seeking input from trusted authorities in various fields, and, if you are spiritual, spiritual guidance - in short, continue to be his number one advocate (a job you are uniquely suited to hold).
You can do this!
Good luck,
