Everybody can sit on a chair and throw front toss or toss or roll GB and flyballs to their kids. With the amount of info out there nowadays parents should be able to educate themselves enough to help their kids if they are willing to learn. Yes I have a bit of an advantage since I played baseball in college but there are things I am still learning.
I never played organized baseball or softball at any point in my life. Everything I know about softball I learned because I was highly motivated to help my DD be as good as she wanted to be. I absolutely agree that (nearly) every parent can help their young player improve their skills, if they make the time to do it, and are willing to make the effort.
