We're flying for Christmas and I want to have a stash of diversions for Kate. Any good ideas? So far I have a mini DVD player, lollipops, stickers, bead necklaces (she loves these), and an Aquadoodle. And an ungodly amount of snacks, obviously

Any other small things I could pack that might amuse her? Thanks!!
Re: Ideas to amuse 19 mo on airplane?
The mini magnadoodle, a couple of new board books, or a small doll. But, usually the movie and some books does the trip for us.
Does she have her own seat? We've always just gotten DS a seat (he had over 25K miles his first year of life!), and because he's been in his car seat, he seems to assume it's just like a car ride.
I gave Miles my Gameboy to use on the plane...
he is now an expert at old school tetris..
well not really but he thinks he is.
the DVD player is your best friend. Also books with mirrors or touch and feel.
Play doh
Flap books and the kind of books with magnets that you can place on the pages
DD is 19 mos and I'm sure she would do Playdoh all the way across the country, and back, no problem.
Do you have crayons? I like the Crayola Beginnings crayons - they wipe off with a baby wipe. DD likes to put stickers on paper then color on them. (Did you bring paper for the stickers?)
When we flew with DD, the Snack Trap was a godsend. It kept me from wearing all of the snacks I packed for her.
