I am no expert on this by any means, but have there been any serious life changing events that might be causing stress, which in turn might cause this behavior? When my DS9 entered kindergarten, we had moved into a new house/neighborhood, AND had a new baby in the house just a few months prior-it took us a while to figure out that all these events had caused stress on him and he acted out in school and home. Not sure if this is your case or not, but we didn't put two and two together until after the fact. We've learned that even the littlest change in environment/life can have a big impact on a child that age. Good luck and I hope you get some resolution soon!
