Huh?

I don't know who is upstairs, but it can't be my Benjamin. Benjamin sleeps as little as possible. He fights naps, he stays up all night singing in bed and most nights only gets 8 or 9 hours of sleep when he should get 12+. So imagine my shock when this happens:

Ben: "Mama, I'm sleepy."
Me: "Are you ready to go to bed?"
Ben: "Yep, lets go upstairs mama."

This happened at 8pm. Thats a half hour before his bed time. He sang for about 5 minutes then it went quiet up there. I didn't know that a day of shopping would wear him out like that!
