We brought our 4 month old to this year's Frozen Four without tickets. As for the noise issue, we knew when he was born that we were going to take him to the Amsoil Arena opener when he was eight days old so we asked the doctor about the noise and he told us that the level of noise at sporting events doesn't come close damaging a baby's ears. He said the only problem would be if the baby didn't like the noise, and he ended up sleeping through almost every game we went to, even after goals were scored.
