I've been making a binder with coloring sheets and other activity sheets like word searches for an 8 year old, then just put them in a binder. You can find tons of them online, all disney themed, all free. I'm not giving it to DS until we get on the plane or at least not until we get to the airport. Any small quiet toys are good. What about those travel size etch-a-sketches, or other travel size games? We'll let DS take his Nintendo DS too with headphones. Anything portable and quiet is fair game for us. I've also been picking things up from the dollar bins at Target. They often have small coloring kits, and I found some Nemo crayons. Figured the new crayons were a great match for the coloring sheets. Definitely don't forget the snacks too.
