Outside of fruits/veggies and other perishable foods, what are your LO's favorite snacks that would be easy to keep packed in the diaper bag for a few days or go to the park with use without getting warm/dry etc? I know snacks like this aren't the healthiest so looking for something that's at least decent but I'm not overly picky about foods. They snack on a lot of crackers and I think they are getting sick of those.
