It also sucks for the other kids in your family if they aren't into sports. This past summer I felt like I never did anything with my 12yo son and felt terrible about it. We talked about it and I promised him we would go fishing more this year and get the kayaks out more as well. It's a difficult balancing act to say the least, especially if you are involved in the coaching side of it.
Absolutely, my son plays basketball, it's a really tough schedule to balance, luckily he's a very understanding kid and I have a wife who's over the top helpful with this! What's funny, my son knows I'm a baseball/softball nut, definitely not a basketball fan, well I shouldn't say "not" but you get my point........and he reminds me of this from time to time!
