Definetly Portable dvd player , they are worth they're weight in gold!!!! Washable crayons, markers, or those fingerpaints that are clear but turn color on special paper, little containers(they have them at ac moore) of dinasaurs, farm animals, ...Also ,and i know there is a site somewhere that has magnetic sets, I've gotten some couple years ago that are disney oriented the castle with the charaters and such...I'll see if I can find the site.. Most of all patience..We've taken our girls since they were infants , sometimes 2 , 3 times a year, my oldest is 7 the baby will be 4 , prepare to be as I call "entertainment commitee"..It does get (let me knock on wood) lighter and easier as they get older..It is aamazing how people can be on planes..My oldest was turning 1 her first trip to disney , it was her first plane ride as well...well we had a man sitting behind us that as soon as he saw us sitting in front he looked at my daughter and said" Oh No.." In a very loud rude voice...My daughter was quiet and very good for her first plane ,as we we're leaving the plane I turned to the man behind us and said" Was she quiet enough for you?" yeah he did'nt say anything, And I don't usually speak up...But that was my baby!!! ,..Sorry for a bit of a drift..Had to share though..Remember..have fun!!!!
