We'll be brining DD to WDW in December when she's about nine months old. Right now she's content to crinkle a piece of paper if need be, but I'm not sure if she'll still enjoy that in a few months. Does anybody have any ideas of things to bring for her to play with on the plane and while we're waiting in line? Preferably things that don't take up too much room. What does/did your 9 month old like to do? TIA!
