DD first trip

[rwjuh2072]

Although my DW and myself consider us pretty well set in the ways of the world, we are going to take DD who will be 20 months in Sept. She is a good traveler and never much of a problem. I'm just looking for any ideas from other parents who have traveled with their young one.

What extra's did you bring?
What did you wish you brought?
Anything you may think helpfull.

Thanks
