We flew to San Diego from Toronto last year with our then 1 1/2 yr old and 3 1/2 year old. I packed way too much for them to eat, however I didn't know how the "kids meals" they had would go over etc...Here are a few things I packed...
I used a thermal lunch bag and put in a frozen water bottle to keep the following cool:
-frozen yogurt tubes
-cheese sticks
-drinks for the kids in their no-spill cups (which I filled later with things from the plane/airport)
-a bagel with cream cheese, cut into quarters
I wanted them to have a few healthier things so I also brought the "fruit to go" 100% dried fruit strips that my son loves.
I let my son pick out a few treats to bring...the individual snack size of ritz bits crackers, cookies etc. I tried to limit the junk, but he was allowed to pick a pouch of the "fruit" ju jube snacks (Mickey of course, as we were also making a day trip to
Disneyland).
My 1 1/2 year old dd was a little harder to plan for as she was still a pretty messy eater...I brought single serving sizes of fruit cups and pudding too. Between all this, a few measly granola bars for the adults, and all the zillion things I crammed into my backpack to keep the kids busy, it made the pack a little heavy, however, I would rather have too much than not enough when travelling with little ones. Any extra stuff we didn't eat on the way down, I saved for the return trip. Since we were travelling about 8 hours with plane changes and layovers, we had lots of little "plane picnics"...
good luck and have fun...
Are you looking for activity ideas too??
