I'm in a similar situation, my girl is about 4 months older than yours. Figured the best approach was to go to a preseason game since its a little less intense and see how she liked it. We tried last year...the noise was too much for her, we spent most of the time in the concourse area walking around, went back down to the seats some here and there. No big deal, it was preseason, I don't really care if I miss half the game. She's almost 3 and we're gonna try again this year. Maybe she likes it, maybe she hates it. After she starts having a good time and wanting to watch and yell and not leave, we can start going to some real games.
