I have 2 children and have been a single mom since the birth of my 2nd child. When I we would travel I had the the kids pack a backpack with anything they would want to play either by themselves and/or together. And a bag with snacks to save of money. I had plastic car tables for their food and drink then later to color etc. The bag would have crayons, coloring book, drawing paper, game boy, etch a sketch, board games that are designed for the car, CD player with headphones of course, etc. It had to fit in their bag. We also would play other car games together so the family stayed a family. Pray/Play together, Stay together.
