My son just started Speech Therapy. It has been a few weeks, and he is having a very hard time paying attention and participating. I'm trying to find things I can do to motivate him to work better (and added bonus if I can use them for potty training). I don't think I can do candy because he can't eat and do his speech at the same time. But he could earn candy. Somehow...

He is 2 and 9 months old.

Any ideas?
