Huh, Mr. Vinyl - it`s really so sad. I have no real knowledge in this field, but I`ll write some of my experience - for supporting you. My daughter is going to the "Montessori" section of local kindergarten. There`re about 30 children, a few of them "children with special needs". It is a little difficult "mix", but I think that`s good atmosphere there - healthy children help, and there`re no big troubles. I think that those children make progress in socialization and learning. Are there in your area something like that? I think that 1-2 times a week on a few hours can`t be bad?
