...but I think it bears repeating.
As much as I love teaching quirky kids, and I do, parents, please, if your child has a diagnosis, or even just an unusual learning style, it's really really helpful for me to know that up front. I've gotten terribly impatient with past students who I thought were just not listening or not practicing, while in retrospect, I now think they probably had learning disabilities of some sort. If I know that, I can work with them better, and it eases the frustration level of everybody involved.
I understand that parents don't want their children judged by labels, and I suppose there's no way for a parent to know that I don't do that, but there's a world of difference between "typical kid behaving badly" and, say, "kid with Asperger's Syndrome getting overwhelmed."
Music can give your quirky child a way to fit into a group. Trust me on this one, I was (OK, am) quirky myself. But let me help them and help you help them by giving me the information I need to make lessons enjoyable for all of us.
