Angus, your DD has a good swing for a 8yr old. Just compare her swing to a few that has been posted on this site. Ask anybody on this site I luv to tweak every swing. Sure, there's 'flaws' in your DD's swing that I would like to see improved upon but, I won't mention any. You as the dad need to read and study more before you start to make changes/improvements to your DD's swing. The pitching will let you know when and how soon to start the
'tweaking'. Again JMHO.
