Children begin to understand that symbols can represent objects, which stems from object permanence. They can also imitate unfamiliar actions after a delay in time. These skills allow the child to remember and repeat words or actions from previous days. Additionally, they begin to solve problems through mental planning (foresight) instead of trial and error.
Vocabulary grows significantly and they begin to combine words into simple phrases. Now children begin to move towards understanding the world through mental operations rather than purely through actions.
