Categorization emerges in a three-year old…
Robert: Have you noticed when he’s playing with toy cars, he organizes them into groups of cars, trucks and buses? 
Laura: Yes. He says, "Leaz are leaz and loze are loze."
Robert: His categorization system. A cognitive skill.
Laura: Trying to make sense of the world in his own way. That’s our little organizer.
Robert: He's starting to notice the differences between cars, trucks, and buses.
Laura: Seems our job is to encourage his curiosity and help him learn and grow. Our responsibility as parents.
