What is object permanence?
Realizing that objects and people continue to exist even when you can't see them or hear them is a necessary part of object permanence. This idea was made popular by child psychologist Jean Piaget, and it marks a significant turning point in a baby's mental growth.
A toddler that has attained object permanence, for instance, will actively search out a toy if it is hidden under a blanket.
