C. Aguliera concert with 1 year old?

Yo

My husband wants to go to Las Vegas for a Star Trek event and we are going to go with our costumes and include our 16 month old. So I was considering that since we are going to be Las Vegas we could see Christina aquilera in concert. I was thinking of purchasing those protective headphones for babies. Are we being inconsiderate for taking her to a concert? We are new parents and need advice
