S.,
I am sorry to hear about the problems your son is having!! I am an in home childcare provider, and relatively fluent in ASL. I served a volunteer mission for my church working exclusively with the deaf. I will be offering a preschool program in which I inted to teach signs. I would be much more vigilant about it with a child who needed it, and am seriously looking into caring for a deaf child (if I could find one) in order to fully immerse my own children in the language. I absolutely love ASL and kids, and would be happy to learn more of your specific desires, and work with you if you were interested. I live in Corinth, so it would be a bit of a drive, but if I could help feel free to let me know.
