Everyone thinks their sibling, cousin, or child is the cutest and smartest baby, but really I think my 3 year old cousin is the smartest AND the cutest. In Chapter 10, you can read about Piaget's Stages of Development: Sensorimotor, Preoperational, Concrete Operations, and Formal Operations. Reading this made me think of my little cousin Elizabeth immediately. When she was about two, I was playing with her outside. I picked up a rock and pretended it was a cookie, then pretended to eat it. She looks at me and tells me "thats not a cookie thats a rock". I thought she was so smart for being so literal, but after understanding Piaget's preoperational stage I have come to realize that she had not yet developed any symbolic behavior. A couple months later when I saw her, she put on one of my old Arby's hats and we started role playing, she asked me if I wanted curly fries, what I would like to drink etc. When I asked her if I could have a sandwich with onions on it she replied "I suppose so", then pretended to right down the order. Now she has gone deeper into the preoperational stage by being able to see the world from a different person's point of view, known as egocentrism.
