We got to Bright regulary which is a 4 hour trip for us. We make sure DD has plenty of snacks & water. Toys & books within reach. We have a portable dvd player but havent had to use it yet. We stop every hour or so, so she can get out have a play & run around. And we try to do as much driving as possible when she's due for a sleep, so more often than not we will drive at 730pm & she'll fall asleep in half hour-hour
