I never helped my son with actual baseball stuff - that was all decided by him, because we didn't know anything about it. Sometimes I pushed him to ask coaches and instructors for advice. I was the chief chauffeur, and I did miss it when he could drive and I no longer had/got to go to the baseball facility and chat with the other parents. I was also the main researcher for travel teams, college recruiting, etc.
Since he got to college, I still research obsessively, but I mostly don't share stuff with him, or even tell him I'm doing it - unless he asks me to research something. Which sometimes he does. On the other hand, he is usually quite happy to talk about baseball stuff, and I think I am better about not offering opinions, but just enjoy listening to what he is thinking.
Thank goodness for HSBBW, where I can get what I need without bothering him!
