When DS stopped falling down so frequently as his depth perception improved that was a big plus for him. If your DS struggles with depth perception like mine did this will directly increase his quality of life and perhaps be a motivator.

My DS also HATED the therapy. What helped for me was to tell him what was on the therapy menu for that night. Breaking it down by short, discrete tasks makes it seem more manageable. We are only talking about 10-15 minutes of work but it seems endless to a kid if they hate the work and it's painful.
