Travel planning with baby

It's done.  We've officially booked our first flight that includes baby James!  I must admit that this is upcoming trip is a daunting prospect.  We've navigated cars, taxis, trains, and buses, but the idea of taking a plane is so different!  There's planning and packing, taking the taxi to the airport, navigating security while juggling all the various and necessary baby items... and this is even before we make it onto the plane.  Once on, we'll have to figure out how James will sit/lay, how to make sure he's secure, how to deal with angry stares from fellow passerby in case he starts crying (I must admit, I used to be one of the starers.  It will be hard to transition to staree!), and, worst of all - how to deal with the potential ear pain involved in the landing.  And, once there, our bags may have been lost.  I personally can go for days without my luggage, but things will not be so easy with the little one. 

Travel used to be one of my favorite things.  Has all that changed?  Have I really changed into the paranoid and overplanning parent?  Parenthood has suddenly taken on a new level of seriousness.
