So you think a four-hour car trip with you, your husband, and a toddler will be no big deal? Well, maybe it won’t be, as long as you don’t mind trying to explain to a bored child why they can’t get out of her seat and roam around the car, or attempting to keep him from throwing his binky out the window, or singing “If you’re happy and you know it, clap your hands” fifty times in a row.Don’t kid yourself, traveling with toddlers is tough and requires a little extra preparation if you want the trip to go smoothly. Unless, of course, you have one of those perfectly behaved children who will look at picture books or sleep the whole time.
