Bring things to entertain your kids
You should always carry some things which will entertain your kids during the journey. For this purpose you can bring along books so they can read, or colouring materials so they can draw and keep themselves busy. If they do not enjoy such activities, you can bring along toys, like Barbies for girls and hand-held gaming consoles for boys.
You can bring music CDs from home and play them in the car, and you can bring CD players or iPods if you are not travelling in your car. Besides music, you can also listen to the radio and let the kids enjoy. The best option is to let the children listen to their favourite songs.
Play car games
You can play different car games with your children like the license plate game or thinking of an animal. You can even let your children sing songs en route to your destination.
Get a portable DVD player or install an entertainment system
You can always buy a portable DVD player or install entertainment systems on the rear seat of your car. You can bring DVDs of animated movies, or your children's favourite flicks, and play them in the car. However, you should know that staring at a screen for a long period of time might affect their eyes. Thus, you need to change the activity after a while, and not let them watch movies for too long.
Bring food items
You can always bring snacks or other food items with you on your trip. Buy (or make) some sandwiches, fruits, biscuits, and chips, and carry them with you during the journey. In addition to these, you can bring juice boxes and even milkshakes for your children.
