I love your thread. There is so much here.
I was recently introduced to switchwords. My 7 year old son and I love using BE when he is upset and OFF to help him sleep. We don't know how they work but we know that they do.
We have also been using REACH to help find things. That has been working as well. I didn't know about COUNT until I read your thread just now - can't wait to try it. I'll report back any results. COUNT and CANCEL will be my new friends.
