BOL Round Table

I'm a long time Cincinnati Reds fan--basically, we lived outside Cincinnati when I was a kid, and it stuck...pretty easy to follow now with the Extra Innings package and such...but I live in Atlanta now. Didn't affect anything, I pull for my Reds on TV and go see them once a year when they come to down....but here's the question. Not so much an issue with my 2 little girls, but now with a son on the way, should I try (not even sure if I can do it) to abandon my Reds and adopt the Braves?? Obviously as Bama grad, my loyalty there will never change. Leaving aside which team you like--when should you switch pro team loyalty?? So the you and the kids can go out and pull for the local team?? Never???
