Yep that pretty much sums up my situation as well, although I have just the one kid. Kids at that age need a strict routine, pretty much from when they can go a whole night without a feed actually, because as Nasher says they get cranky, don't want to go to sleep etc....
I live a long way from Melbourne which is the reason why I have not been to a game with my kid since she was born but plan to next year. But this new time will make me rethink that
