Grapes! They travel pretty well, especially if you have room in your carry-on to store them in a plastic container. They are so juicy you don’t have to worry about dehydration on an airplane. Just make sure to bite them in half for smaller kids.
While not for baby babies, for slightly older ones and toddlers, chewy granola bars like the Quaker Simple Harvest ones are great- the apple cinnamon and nut/honey flavors and good and not colored, and even if you do lose a piece, while it is a bit sticky, it also cleans up well. And they fill up kids pretty well, also, so you don’t get the 400 snack requests either. But bring a drink, or they’ll be begging for water! Just don’t bring the crunchy kind of bars, or you’ll be picking teeny bits out of carpeting....
Raisins work really well as do veggie sticks like carrots. Cheerios are also one of my favorites!
Quick caution- a few of these suggestions need to be tempered by age- for instance; raisins, grapes, and carrot sticks are all choking hazards for the littlest travelers. While they are great ideas for middle range toddlers, I think the common wisdom is that they aren’t safe for kids under about two years old. Mostly though, like everything, you shouldn’t try anything new when traveling. Stick with what you know.
PUFFS! Or according to my daughter “pu pu pu”. Like the gerber graduates stuff, it melts in her mouth. This was also her first finger food. I usually make a “trail mix” type thing with cheerios, puffs, yogurt melts, and graham cracker broken into smaller pieces. She loves the variety.
Trader Joe’s makes an applesauce “crusher” that is in a shelf stable foil pack with a recloseable cap. No additives other than vitamin C, can’t recall if its organic or not BUT much easier than trying wrangle jars of applesauce for me at least.
Gerber Graduates Yogurt Melts. All the goodness of yogurt in a small hershey kiss-like shape. Personally, I think they taste like chalk but my daughter loves them. They aren’t organic BUT that is a small sacrifice to make when we need a quick/healthy/easy snack. She can not get enough and makes me wish we never taught her the ASL sign for “more”.
