An individual I work with drops her drink bottle on the table and floor. I want her to learn to place it on the platform.
The platform helps her to sit more upright while eating.
I cut into the white Thicket container ( I have several of these ) so that it can slide onto the edge of the platform. It was at first bit too tall for the cup and she couldn't get it out, so I cut around the top of the container to remove some of the plastic and then wedged the pieces together and taped in place. Notice how it got shorter.....
I think that she will learn how to place the cup in the holder if we guide her hand, praise when she succeeds and give her more food after she puts her cup in place.
I have been playing around with figuring out which corner of the platform to position this to. It stays in place pretty well. So far the lower right corner is working best.
