Helping someone overcome fear so they can perform the task before them is huge. It takes small, incremental steps of desensitization to help someone over that hump sometimes. Sometimes it requires pushing them in the deep end of the pool and let them figure it out. In the case of my sister, she needed the slower method and a lot of convincing. We started out with just figuring out how to get up and down off the floor. Then we moved to sitting on her knees and backside repeating the falling motion over and over. She needed to overcome that fear next. This went part went on for some months.
