Allison,

I know some folks have said that their kids have actually done better in a less academic pre-school for a part day. My DS was in a great YMCA preschool when he was little. They had swimming lessons, lots of books, a few computers with educational games (which DS Loved because he could work at his own pace), lots of free-form art materials, story time, great field trips, dance lessons, tumbling lessons,and music lessons. when DS was bullied (a couple of the kids liked to take his blankie and make him cry), the teachers worked with the "bullies" but they also helped DS learn skills that would make him less of a target. I think we owe some of his confidence and social skills to these kind perceptive teachers.

I'm wondering if you could find something like this where you are and then try to meet his academic needs at home by answering his questions and exporing his interests with him informally.
