From birth, babies are constantly learning as they experience different sights, sounds, movement, taste and touch sensations. As they move about their environment, babies begin to understand that their actions can cause things to happen. They imitate the actions of others and begin to anticipate events. Toddlerhood brings emerging problem-solving skills, make-believe play, and the ability to recognize things that don’t belong. Throughout the first three years, play and exploration lead to the development of memory, language, and increasingly complex problem-solving skills.
