Calvin's trike

A couple weeks ago we picked up a cheap little trike at Target that fits Calvin. He has another one that matches Violet's bigger trike but his legs aren't long enough to pedal this year. I have had the little one inside the house for awhile. He first got on it and couldn't do anything. He put his feet on the pedals and didn't know how to push. A week later he could sit on it and push the pedals backwards. This week he just figured out how to go forwards. He just took off and went around the house, around the kitchen island, through the eating area, and around the house in a circle through the dining room past the front door. He sticks to areas where there is hard flooring, avoiding the carpet. Violet has always whizzed around the house on the trike but now I can't tell by the sounds of it who is on it. I can tell he is proud of his new found ability. He yells "watch me!" all the time.
