sleeping in the garage

One day last week Courtland and his brothers got up from naps when the older boys arrived home from school.  While the kids were showing me their school papers, Courtland went out and started riding bikes in the garage.  Not 5 minutes later, Kolby told me Courtland was asleep.  I went to find him sleeping like this: sitting up in his toy car, in the garage.  Apparently he hadn't really gotten any sleep at naptime.  I left the doors open from the garage into the house and out into the back yard, and checked on him several times, and he had a decent little 20 minute nap just like this.
