Here's how Jennifer keeps the car drowsies at bay:
Thought I'd share: My kids (2 1/2 and 4 yrs old) fall asleep very easily in the car. Sometimes it's a good thing, but sometimes they fall asleep during 15-20 minute drives home, which then interferes with their nap schedule. I can never quite transfer them to their beds without waking them up and then they are crabby the rest of the day from not getting enough rest. My latest trick in keeping them awake is to engage them in a game of "I spy." We all take turns "spying" on objects on the road and guessing what the person is spying. They are completely engaged and it works every time.
For us, I Spy also solves the inevitable sibling sniping that goes on in the back seat. Rather than engage in endless refereeing (and, in so doing, pay attention to behavior I'd rather ignore), I yell out "I SPY…" and suddenly the whining stops and everyone's playing.
