Wow. I had no idea that I might be helping him with this as a teen. NO idea. I knew he was developmentally behind, but I had been left with the impression if we worked hard at it and kept doing the routine enough he’d get it as a young kid. I’m rather floored. Obviously I am asking too much at once if it’s likely going to be a process that takes years. Thank you everyone for your feedback, you’ve opened my eyes a lot!
