With your little ones in tow for a holiday or summer vacation, plan your travel time around your kid's sleep habits. Tuck them into the car early so they can sleep through the initial hours of your holiday travel time. Devise a way for your kids to stay occupied when they do wake up. Car-kits for kids are a great way to cure the doldrums when traveling. You can combine art supplies, books and CDs with headphones for your children to enjoy.
