1. Defy your spouse's request to keep packed items to a minimum! Let each kid bring their own pillow, blanket, backpack full of stuff, and electronic equipment. So what if you can't see traffic out of the back window of your van? Isn't that what rear and side mirrors are for?
2. Do not leave a rest stop until everyone has gone to the bathroom, especially the kid who claims "I don't have to go now."
3. When desperate, give them sugar.
1. Bottle of water
2. Gum (sugar-free or regular)
3. Deck of cards (great cheap entertainment for hotel rooms and in crowded restaurants waiting for your meals to arrive)
4. Clip board (mini-travel desk!)
5. Bound sketchbook (so the pages don't fall out) for journal writing; drawing; playing tic-tac-toe and hangman; reviewing hotels and restaurants; writing silly limericks; making signs to communicate to other cars and trucks ("honk if you like mashed potatoes" was one of my kids' favorite signs); and keeping lists of: state license plates, animals they spot, cars they like, cool names they wish they had instead of their own boring name, things they hate/love about traveling by car.
6. Markers of all shapes and sizes. Younger kids like the scented markers. *Hint: take out of boxes and put in zip-lock plastic bag.
7. Kneaded Eraser
8. Lead pencils and colored pencils. See* in #6. Remember you take a risk packing crayons, they melt in hot cars.
9. A great age appropriate, FUN paperback book or books (not mandatory books from their schools summer reading lists). Find books by their favorite authors. Ask your local librarian for entertaining books. Libraries have paperback copies as well hardback books.
10. Correspondent's kit. Tuck the following in a large zip-lock plastic bag: their friend address book, blank postcards, STAMPS, stickers, water-proof pens or markers, blank cards and envelopes. Encourage them to write to their friends throughout the trip. And stop to mail!
11. One-two packs of favorite candy. Keep back up supply with you to dispense gradually.
12. Terrific sunglasses
13. Healthy snacks- a banana, trail mix, or bag of carrot sticks
14. Plastic bag full of disposable hand wipes
15. Pack of tissues
16. Comic books
17. Dime store treasures: paper doll set (pre-cut and put in folder), animal stickers and album, Silly Putty, Fuzzy Magnetic Mustache Man, Kaleidoscope, etc.
18. Personal tape player
19. Books on tape, age appropriate. Books on tape are often more expensive than the books themselves, but at most libraries, you can borrow them for free.
20. Tape of favorite musical group
21. Disposable camera
22. Cheap binoculars for spying
23. Flashlight for reading/writing/drawing when it gets dark.
