Cece -
I've never homeschooled, but I have heard that children who have been in tight places at school need a little vacation when they first come home to learn. So bring him home now and learn on the way - if you can find us, you can homeschool. Maybe not forever, but most of the folks I know aren't thinking in terms of 'homeschool' v. bricks and mortar - they are getting to know their child's needs and putting together a series of situations that work for their child.
It's a lot of responsibility, but so is parenting in general, parenting a special needs child in particular. What are your son's interests? How does he like to learn? Do you know anyone at all local who homeschools?
Best Wishes,
