Tractor = anything with wheels

We do not know where he got the idea...but somehow Elias has determined that anything with wheels is a tractor.  Trucks, cars, trains, lawn mowers, strollers, etc.  Tractor came shortly after uh-oh and Da-Da.  Give him a "tractor" and he will be entertained for hours.  This, combined with going outside, is his current picture of heaven.  Reminds me of Yaconelli's Dangerous Wonder.
