Im not as experienced or knowledgeable as many here but we had several girls on our roster this year with the exact same problem, almost the exact same swing. Take it for what its worth but the following is exactly what we did and almost all of them were much better hitters by the end of the season.
1. Problem #1 was dropping of the hands so we simply lowered their hands to begin with. Instead of focusing on the high triangle, we simply lowered their hands to almost the "at rest" position, hard to drop them if they are already there.
2. Problem #2 was sweeping of the bat or long, loopy swings resulting in being behind the ball too often. Sounds crazy but at first we took the bat out of their hands and utilized a 3-in. swimming noodle (ok, quit laughing). To teach them to "throw their hands at the ball" rather than looping around to meet the ball, we had them grab the noodle about 2-3-ft. from the bottom (choke up). The goal was for the bottom end of the noodle to hit the ball off the tee, then finish rotating with the noodle swinging across the tee where the ball was. Stupidest thing i had ever heard of when one of my coaches recommended it but i was amazed at how quickly the girls started throwing their hands at the ball and finishing inside of it.
3. Simply moving the tee up in their stance. Its amazing how many knowledgeable coaches/parents tee the ball up in the middle of the girls stance without thinking about how much it changes the swing. Simply getting the girls to think "hit the ball in front of the plate rather than over the plate" helped with the timing and even the hands.
Teework............teework..........teework. I dont think a player at any level can hit enough balls off the tee. Everything else can be perfected without throwing one single pitch to them and when the teework is perfect, then its just a matter of figuring out the timing.....everything else is automatic by now.

Ffs you are not helping her. Random photos of MLB is doing nothing but confusing her father. Why don't u offer up some help and put this garbage away. It's way to early for this. My advise. Throw away the multi t ideas and keep it simple...don't get caught up in this garbage.
