Road Trip Snack Boxes for Kids - I made these for this summer's trip and it was a huge hit. I found the boxes in the craft section at Wal-Mart and included a variety of salty and sweet treats. Then on each leg of our trip (divided up into 1-2 hour increments), they could choose one or two things to eat. Very convenient on us as parents and the kids love it, too.
My brother didn't just 'smash' his finger, he actually LOST the end of his finger in a door-slamming and it had to be sewn back ON!...so this is a smart idea. *Toddler Proof Door Stopper - use a pool noodle! No more shutting doors or smashed fingers :)
