In addition, pack each child a backpack with art supplies, toys and books. Good items include colored pipe cleaners, kazoos and a deck of cards. A cookie sheet can also be good to have along. Kids can use it for magnets, as a raceway for small cars or as a foundation for blocks and Legos. Kids as young as 6 can also learn to knit.
Boys often enjoy it as much as girls.
They can give each child a roll of nickels at the start of the trip. Every time a child asks that question, a parent takes a nickel away. Then the parent can think of a way the child can earn the nickel back. To reduce monotony, family members can also switch places in the car every so often. And don't forget about parent timeouts.
