The Little Engineer

This is a toy car among several his dad had waiting for him when Connor arrived in Japan. For a long time, he seemed relatively indifferent to these toys with wheels, but lately his interest has increased. This before-bedtime pair of pics (Aunt Shannon, you recognize these pjs?) shows the little scientist revving the wheels, then slowing them down with his fingers, in an attempt to figure out just what was happening. Notice the furrowed brow. I wonder if he got the answer he was looking for? (by Elizabeth)
