I've said before that my eldest son, Puck, has a learning disability. And my headline might be a little misleading in this regard. My son can learn. And given the right environment, with some accomodation, he actually learns very well.
The person who doesn't learn is his father. He hasn't learned that negative feedback to a child with learning disabilities just lowers their confidence. He hasn't learned that he is fairly consistently the source of negative feedback to my son.
