How to make travelling with kids easy?

Travel diary, yeah. it sounds like for adults, but hey, they can write stories and draw pictures, can't they? plus that'd make them busy so wont disturb you much (if you wished that lol) Plus airlines these days focus a lot on kids entertainment content in-flight, so there would be plenty of kid and cartoon movies, games for them to play and fiddle with What do you do generally? Are they too mischievous or something? heh
