My big one is graham crackers because they're so easy to just hand to her in one big piece. Other than that I usually just take cut up fruit, and sometimes goldfish. I need some better ideas!
It really depends on where we're going. My kids are 2 and 6, so they don't really need snacks often, but if they do, something like pretzel sticks and drinks, maybe some grapes.
I make sure I ALWAYS have snacks no matter where we are going because they are the only thing that will occupy my daughter and keep her happy if it comes down to it!
How hard are raisins for them to chew? My daughter has 8 teeth, 2 of which are just erupted molars
Multi-grain cheerios, gerber puffs, Teddy grahams.
Those little fruit puree pouch things. they make them for babies and toddlers. my son is two and still loves them.
