Sticker books are the top recommendation — toddlers can spend an hour engaged with them. Busy books, playdough with a couple of moulds, and a deck of cards also work well. For screen-free kids, try a slideshow of family photos or videos of things your child is obsessed with. Strategic snack timing helps fill gaps. Doing walks up and down the aisle burns energy. Accept that it will not be perfect, and many parents report their toddlers surprise them by being much better on flights than expected.
