Okay, I'm sorry for yelling before. Let's try this again.?

I am going to be a bride's maid in a wedding and am brining my six week daughter. My husband and I are divorcing and he will be out of state the night of the wedding. The reception starts at 7 and ends at midnight. I want to stay for the whole reception. I am not hiring a baby sitter because all of my baby sitters will be at the wedding. I plan to put my daughter in her baby carrier in a quiet corner at bedtime. Is this a good thing to do or should I leave earlier?
