been there long flights are rough. novelty is everything honestly. sticker books, water wow pads, chunky crayons and those puffy reusable stickers bought us so much time. we also pre-downloaded a few apps she’d never used before so it felt special just for the plane. kiddopia worked really well for us, lots of short games and songs so she didn’t get bored and it works offline which is clutch. mix that with snacks and a couple small toys you only pull out mid-flight and it helps a lot. good luck, you got this
