This past summer I began babysitting a family of three, with a three-year-old girl, a one-year-old boy, and a newborn little girl. I had babysat many children before, but never kids of such young ages, so at first it was very interesting to watch how the smaller children behaved. I was especially intrigued by the one-year-old boy, named Charlie. He was learning and developing so much every day, and it was fascinating to see him try to learn how to walk, talk, and interact with his siblings. He was so curious of the world around him and would crawl all around the house looking for anything fun he could get his hands on or put in his mouth. His favorite thing to do was open the kitchen cabinet with all of the Tupperware containers and take them out and stack them or put them on his head. At the same time, I would try to teach him words by saying them and having him repeat them, but he could only say simple words like “hot” or “mama”. If I would say other words that he didn’t know, he could make the sounds of the words but not say them clearly. Charlie was in the sensorimotor stage of his development, where he was experiencing the world through senses and actions. He wanted to look, touch, grasp, and mouth everything he saw in order to take all of the new information he was experiencing in and interpret it. The sensorimotor stage extends from birth to about two years of age. Charlie was one when I was babysitting him, so he was right in the midst of the sensorimotor stage where everything he saw he had to touch. Charlie used trial and error to gain an understanding of the world. Even during the short time I was babysitting him during the summer, I saw him develop and grow in so many different ways. I gained a new understanding of how children develop and learn about the world around them, and even had so much fun watching how Charlie and his siblings reacted to new experiences
