1. Write out a to-do list
As well as noting everything you need to pack and finish up, jot down all the songs and games (I spy, roadside bingo, 20 questions, hangman, word association) you can think of to sing and play on the trip. Crossing items off the list can become a game in itself.   
2. Start calm and carry on
When you head out, try to lull your kids into a meditative state. Keep things quiet and very low-key. Whatever you do, don?t mention any of the snacks, crafts and games you have stashed or else they will be clamouring for everything before you even get out of the driveway. Just drive. When this works?and they fall into deep imaginary play or even fall asleep?it?s golden. And if it doesn?t work, proceed to No. 5.
3. Be sneaky with snacks By keeping the treats secret, you?ll always have something in your back pocket. You could try rationing out snacks in a fishing or a candy tackle box so each one gets its own little space.
4. Hire back-seat drivers
Involve the kids in the planning and show them the route and images of sights they?ll see. Get an extra map so they can follow along and even help navigate if your GPS fails.
5. Pack a bag of tricks
Pull out easy craft supplies, a new toy or other items as needed, ensuring the items can be secured and/or are soft enough that they won’t become a projectile in the event of a crash. Do not, under any circumstances, let your kids see what else is in the bag. Keep them in suspense.
