Travel angst

The to-do list is in high gear this week.  Very soon, we are traveling to see my last brother get married.  We are so excited to hang out with family, pass babies from lap to lap, retell funny family stories that we have all heard at least 20 bijillion times already, watch Little B be the most awesome flower girl ever, and, of course, watch my brother say "I do".

But right now, I am a busy bee trying to get us all packed.  And in addition to that, I am having a bit of angst.  This is Little B's first trip on an airplane.  I have heard horror stories about screaming babies, car seat checking nightmares, diaper blow-outs, and crazed moms that could burst into flames at any moment.  I don't want to be flameable.  So what is a girl to do?

I need your words of wisdom.  What are your tips and tricks that will keep me from hyperventilating with a demon baby strapped to me?
