Anth, I remember putting my daughter's stroller in your vehicle way back in the day when I brought her to the tailgate. I know some stadiums(like GABP) have areas set aside for infant care(with a stroller check, changing area, etc.), but I've never noticed one at CWS.
I remember my girls at that age both having major issues with the noise, especially the sudden pops from the crowd, fireworks, etc. It got to the point where I didn't take them back until they were 2 or so and could be prepared for the noises.
