20 month old on plane

[2155User]

Have travelled numerous times with DS, but now he is getting a bit older, I was wondering if anyone had any good ideas/tips for keeping him entertained on a plane?

On previous flights he has always slept, but the combination of a 5 hour flight + him being older means this is less likely.

Have got the obvious such as iPad with downloaded movies, snacks, stickers etc but wondered if anyone had any other ideas

TIA

Small new things to produce every hour or so - a new book or little toy.

Lots of snacks! Couple of new toys or books, things like finger puppets are good fun in a small space. We resorted to walking up and down the aisle but I guess that isn't allowed at the moment.

When my DC was that age, he loved playing a game where we'd stick post-its all over the back of the seat in front of us and he would peel them all off! He also loved sticking post-its on himself and me! Amused him for ages. Likewise for clothes pegs!
Take a small bit of bubblewrap for popping if you have some at home. Pipe cleaners can be taken in hand luggage and are fantastic fun.
Put some snacks in little envelopes for him to tear open. Raisins and Cheerios work well.
I've also had success with:
Melissa and Doug reusable sticker pads
aquadoodle travel mat
lift the flap books
A pot of Play doh
A set of stacking beakers or nesting eggs for playing hiding games with small items of food like raisins and Cheerios
3 or 4 finger puppets
Sticklebricks
Toomies eggs
Several small envelopes that you can put a few raisins in for him to tear open.
The humble balloon! I always pack a few, and there you have a game of catch whilst waiting at the airport.

Thanks for all the brilliant ideas!
Raisins and Cheerios in envelopes is a bloody fabulous thought, thank you; DS will love that!
