As stated before, this is a changeup. She was out in front, and changed and adapted and did what she had to do to hit the ball. Nothing more. Most kids would not have hit this ball, so I don't mind you posting it one bit.
2 faulty swings seem to equal a pattern to me. How bout some side video of your DD Lenski? It's easy to critique other kids swings, for the record I've posted a ton of video of my DD on here over the years so I know how RD & you feel.
