Dress shopping postponed...niece is here!

I don't know if any of you remember, but the same week I got engaged my sister found out she was prego with her second child.
Me, my Mom and sister were supposed to go dress shopping for the first time tonight. Well my sister is in labor and on her way to the hospital. Looks like dress shopping is getting postponed.
If my sister and I weren't so close, I would really start to think she is trying to upstage me
