Hi N.,
My name is J. and I have a daughter, 13 years old with ADHD, Bi-Polar, Reactive Attachment, and ODD. I can relate what you are going through. My daughter just spent a year in treatment in group homes and residential hospitals, we have had ongoing therapy for over a year and continue to do so. The book "The Explosive Child" is not about ADHD, but I found it helpful in discipling with empthany and understanding. I would be concerned about medicating a child who is Bi-Polar with ADHD medication. Before we found out my daugher was Bi-Polar, we had been medicating for about six years with ADHD medication, we have tried them all, and the end result with our daughter was physcosis. I am not an expert in this area, just an experienced mom. We have been dealing with it for many years. It might be something to ask your child's doctor about. My daughter is now being treated with Abilify and it seems to to be best medication we have tried so far. It is an all around kind of medication, it helps with physcosis, it is a mood stabilizer and helps the impulsive behaviors caused by the ADHD.
If you have PLUK (Parents Lets Unite for Kids) in your area, they have been a great resource for me as well. If you haven't looked into NAMI yet, I would highly recommend at organization as well.
I feel your daily frustrations and can relate more than you know. Always here if you need some support. I think when we face the frustrations of parenting a child with any kind of behavior disorder, the hardest thing to have is empthany, but it is can be most effective. Don't give up.
