I knew we were going to have breakfast at home and lunch already in our destination, so I didn’t bother with very filling food. Instead, just some things to calm down and reload the body in crucial stages of the trip (queues at the airport, etc).
I got a little ziplock bag full of small cereal-type snacks, and another one with nuts. Then got some fruit pouches and cereal bars. I don’t usually buy fruit pouches or cereal bars, so this are, for The Older One, real treats.
For emergencies I got a little bag of fake-gummy bears (they don’t really have sugar but agave instead, because: who wants a sugared-up 2 year old on a flight?!!). and split them into small wraps (4 each) closed with masking tape.
Add a pack of corn crackers (my favourites) and that is it, a little (that is crucial!) bag full of yummy things which don’t put anyone on a sugar rush. On the morning of the flight I ended up adding a couple of apples and pears, and they also didn’t make it to the destination 😉 The dry snacks did, though, and were eaten while on holiday.
