Here he is trying for the 100th time to ring the bell. You need to press down and release quickly, but he presses down and holds it and slowly lets it up to release it, which does not cause the bell to ring. Poor kid. He got very frustrated that he couldn't make the "ding" sound like everyone else seemed to do so easily. Oh well...he'll get it one day.
again....trying to show him how the bell works!
