You know when your kid has been to the doctor entirely too much when he builds an otoscope out of tinkertoys. This is Caleb's first creation with tinkertoys that is representational, meaning it represents something real. Normally he sticks stuff together randomly, but today he walked up to me with this, stuck it into my ear, looked in the hole on the other end, and declared, "Ear, good." Then he walked around to the other ear, stuck it inside, and said, "Good!" Apparently I don't have an ear infection, which is great news! I'm going to make a doctor out of the little guy yet!
