This little girl loved it. she stood on top of the horse, squatting to pick up each ring. I held the bottom of the "stack" while she pushed the rings down. I think that she just enjoyed the novelty. I was not able to control the camera and work with her while standing at the same time, so just filmed her sitting to stack the rings.
I saw a little boy smile for the first time when I gave him this to hold. I have only worked with him 4 times, so I am sure there will be plenty more smiles to come.
