Explanation:

According to Piaget, the preoperational stage of cognitive development is the second stage. It is initiated when the child is around the age of two years old, lasting until the age of seven. Children at this stage are able to work with symbols. However, they are still unable to do logical (concrete) thinking. During this stage, children present animism - the belief that inanimate objects are alive and have feelings. That is why Sarah thinks the stars twinkle because they are happy.
