I think I get what your saying. Yes her hands are doing all the work. The body is not aiding her swing at all. Or her hands are loading to soon causing drag. Not sure. My best guess.
Really like this whole comment.What I am seeing is the most common error of all young batters. Her hands drop first. She first needs to understand that those hands dropping are what is causing 90% of the problem. All those stuff about fyb and separation, and on and on are only useful once the correct path has been established. Her top hand never establishes an "oar lock". Have her hit high tee, front elbow up, back elbow down. (I really like this. )
Ball must go straight out or slightly up. Learn to swing from here first. Then once this becomes her swing move on to the other stuff.
