Leaving my baby too soon?

Erika
There's this 2 day concert in October that my SO is begging to go to. At that point, our baby will be almost 2 1/2 months old. I told him no. Part of me wants to go and get away for a few days, but the other part of me says hell no, I can't leave my baby girl! I can't stand the thought of her missing me. What do you guys think? How long did you wait to leave your baby?
