If Tucker began to pinch, then they were to take the toy away from Tucker for varying lengths of time. Tucker's parents were asked to record the number of times Tucker pinched during each day. Tucker stopped pinching after the first three weeks of treatment. Then, the treatment program was gradually withdrawn over the next month.
