Ok - she needs to request a basinette for younger DD. Even if they don't use it, as M says it gives them a ton more foot room - essential for wriggly toddlers who want to be down all the time and all the schmutz you seem to travel with when you have kids!

She'll need to ring the airline to request it but it is well worth it.

Things we used to amuse DD and DS on our recent trip: iPhones with movies/games they actually liked, the in-flight entertainment system (depends on carrier/length of flight, hence our iPhone backup), a really good one was stickers - kept them amused really well. Sticker book with stickers. We took books on one flight but the problem with books are that kids books are so heavy at that age (board books) and take up quite a bit of room which is a pain.

Food - take your own snacks, sultanas, crackers, water bottles. The in-flight service wasn't quick enough and ours got hungry before the food arrived.

Ask for a kids' entertainment pack - DD loved hers, she coloured and looked at the book, DS looked at the book and we pointed things out on the pages ("Where's the doggy? Where's the star?") which was good.

Is she flying with anyone else? Our parents provided entertainment - "Let's go for a walk to see Nanna and Pop!"

Good luck to her - it is tough. Well, we found it tough with our two and you know how active they are
