Navigating Tricycle

Today is the first time JJ navigates his tricycle when I pushed him around in the evening. I have been pushing JJ around in his tricycle in the evening on daily basis, and everytime I guide him to make a turn, I will say turn left, turn right, go straight, etc.

To my surprise, JJ navigates his "bike" without me giving him directions today. He takes charge of where he wants his "bike" to head on. When the bike goes a bit off left, he will slightly turn the bike to the right and vice versa. It's indeed a surprise!! I am sure JJ has moved ahead to a new stage of milestone! :o)
