This explanation was the foundation of Lily's understanding. "You get paid for resting your chin on this object for a while."
I moved it in hand L and R, up and down, etc (L1 Target) until I placed it on the pause table. She didn't have to do anything more than rest her chin on it for a while.
Only after she "got" this with duration, did I then introduce scent to the teeny chain. Still just the same container. Not making choices.
All I'm saying is.....that's what worked for us.
This happens to be the same container that Jan has selected for her scent pots. This is an empty can that has not been washed. It does not have any holes in the top. I'm just using it as an object in hand for Lily to touch and rest her chin on - her scent wheel alerting behavior.
