The plane of her swing is really bad right now and its causing her to hit pop ups, weak line drives and choppers.
hit pop ups, weak line drives and choppers.[/
Do you see the difference between the plane her shoulders are rotating on and the plane the bat is swinging on?
Here's a drill for you. Set up a tee shoulder high and tell her to drive the ball on a level to the ground line. Just for fun practice it first so you can do it easily just to motivate her to beat you. When she can drive the ball on a line, video her swing doing just that and show her the difference between that swing and this swing.
Once she fully understands the difference, begin to lower the tee watching to see if her swing plane starts tilting forward like the swing you posted above. If that happens, go back to shoulder high.
Enjoy the parent daughter time.
