I don't know what the deal is, but my kids rarely sleep in the car. On the way to Indy, the girls slept for about 30 minutes of the 4 1/2 hour drive. Lucy screamed off and on for about an hour and a half. Then on the way home, Lucy fell asleep about 20 minutes before we got home and Norah fell asleep about 10 minutes later. They both screamed off and on unless we had a movie going. I am not about to let them watch movies the entire drive - so we listened to the screaming. Seriously, what's wrong with my children?
