I think live pitching would be very beneficial for her as well. I agree trust is a big part. It be interesting to start a live pitching session with her and don't tell her anything. Are you still seeing the same timing issues? If so, instruct her to start at a certain point in the pitchers process.. forget about hitting the ball.. just focus on getting started and not cheating the sequence. I think it would be a light bulb moment for her. You could also do that with dry swings as well to get her comfortable.. you could imitate a pitcher going through the process and have her complete her full sequence. You know your kid better than anybody and obviously you have a lot of experience.. just offering my 2 cents
