I think I finally have made a break through on getting my daughter to understand that the cannot lean back and stay back in her stride. The video below is last night. I had to change my terminology in what I was saying to her. So instead of saying "Stride", I said to "Walk." That seem to make the light bulb go off for her. While not perfect, I think its a good start. Maybe that term might help some of you with younger kids batting.
