I've noticed that a lot of the videos that get posted on here show hitters that open up their front foot as they stride. My DD use to do the same thing. In my DD's case, we did thousands of reps where she would stride to toe touch and pause with her front foot open at about 45 degrees. This conditioned her to open up her front foot as soon as she began to stride.
When I compared her swing to slow motion video of the best I noticed that many of the better hitters keep their front side closed as they stride. I consider this to be an absolute to a good swing. We've since gone about trying to fix it and IMO it's made a positive difference in her dynamic balance and weight shift. If you're working with your DD on her hitting, it may be something you want to look at. I actually believe that a lot of kids keep the front side closed naturally, and in some cases, parents, instructors and coaches like myself accidentally coach it out of kids through bad drills.
