Holiday Travel with Toddler

Driving for miles in a closed car with our toddler has led us to the inevitable place of realizing that we need to get our child some kind of portable gaming platform. Yes, we've played 'I Spy'. Yes, we've answered all basic information gathering questions at least 30 times over. After about the 200th "Daddy Daddy, Mommy Mommy...!" we see that there will be no semblance of peace. Our child is a sleep 'resister' and continues with the eternal questioning until we are about 3 exits away from our final destination; then,....she sleeps. Okay..., it's funny I have to admit. So sleep, and then in about 5 minutes we'll have to wake you to go inside Nana's house. (She'll sleep good tonight for sure.)
