The mind of a mechanic in the body of a 3 year old

Every time I took Isaac to WalMart he would insist on going to the bike section and riding the little red bike. So when his birthday rolled around we bought it for him. The funny thing to me is that over the last two days he has spent more time studying how the bike works than actually riding it. He has such an innately mechanical mind. He loves to turn the pedals and watch the wheels go around. Last night he said ‘m om, the tracks are moving around and around.’ It took me a moment to realize he was actually talking about the chain, but I had never taught him the word chain so he equated it with track wheels on a bulldozer. He continues to be so enthralled with how the bike works, constantly telling me about what he’s discovered and naming all the parts. Today I had to tape the handlebars to the floor so the bike would remain upsidedown while Isaac moved the pedals with his hands and studied how the gears worked!
