My mom put together some great things for my kids once for a road trip from Utah to California. She divided the trip into 4 categories: mountains, farmland, desert, and beach. Each category had a bag with toys, books, songs, treats, poems, games, etc. She got dollar store toys so that it wouldn't matter if something got lost. They were play sets like trains, farm animals, rubber insects and lizards, sea creatures, trucks. So 3 times during the trip we packed up all the toys and books and traded it for a new one that was specific to the area we were driving through and the things the kids would see out the window. There were also things like drawing pads and pipe cleaners for times when the kids wanted to be creative. We stopped at McDonald's or roadside parks about every 2 hours so the kids could wiggle. And we watched one DVD each day to give the grownups some quiet time because kids in a car for many hours can get very loud, especially little ones who are tired of their car seats. Oh that reminded me of something else. Check the padding of the car seats. It can make the trip much better on little bottoms to sew an extra layer of padding into the seat cover. I hope you have a great trip!
