Your older daughter also needs to simplify her pre-motion. She's doing 2 of them, and while I'm not sure it's technically illegal (every umpire seems to have a different interpretation of that rule), someone may mention it. It's also just plain unnecessary.
Tis is what I was coming to say. There is no need to waste that much energy. Putting the ball above the head in pre pitching motion achieves nothing (besides looking cool ill agree with that!) but taking energy from the pitcher.
