Going To Major League Game

So we have tickets to go to a Major League Baseball game when my baby will be right at 3 months old. Is this too much? I was worried, but it’s indoors and I’ll be wearing her the whole time so germs don’t scare me as much and we have ear muffs for her to block noise. Any opinions or tips? I’m sure it’s okay, but she was premature and is 9 pounds now at 2 months so I never know when to treat her like a newborn and when to treat her like her own age.
