Think how mad a nonfamily member that paid a lot of money for their ticket is sitting next to a kid that gets in free that isn't well behaved. Not that lots and lots of paying adults don't misbehave, too! Don't get mad, I'm sure yours and most kids are well behaved. I just remember reading the 5 and under are free policy on the Saints website somewhere and was glad I wasn't next to one of them, 3 + hours is a long time for anyone. Those seats get smaller and smaller each game! That being said, I hope your 4 y.o. has a good time and has one of those cute cheerleader outfits!!
