Traveling and the fat girl

Tomorrow will be my first traveling experience post WLS. I am still experiencing serious fat girl airline seat phobia. I know in my head that my ass is smaller and I won't have nearly as much trouble as previous trips, but my head has not caught up, and I am nervous. I'm also worried about eating all day as we travel. I am trying desperately not to fall into eating whatever is available because I was unprepared, so I packed a few protein bars, shakes that I can mix up pretty easily with some cold water, a carb-balance wrap with Power PB, and even some cheese sticks. Yes, by the time I am looking for them they will be warm and floppy. I don't care. Been there, done that, still fills me up. I hope I can resist any temptations typical of airports (high carb/high fat, etc)
Of course I am worried about Josh as well. (Are you sensing a trend?) He's still getting over being sick, as in, still has 7 days of antibiotics to consume, and he's going to be cooped up in planes all day. There is only so much you can ask of a toddler. But, we do have an arsenal of "tools" (snacks, portable DVD player and Mickey Mouse DVD, coloring stuff, play-do) and I am praying it will be enough to keep him distracted from the fact that he can't walk all around the airplane. We'll see.
I have to stop worrying now and go to sleep, because we have to be up at 4:30. Yes, A.M.
Night.
