So active, in fact, that they may confuse fantasy and reality. Being able to use inanimate objects as players in an imaginary game or story is a normal developmental milestone at this age. And don't be surprised to find your pre-schooler talking to the plastic horse, tree, or simple wooden block. That is all part of the story. Imaginary friends are all part of this development.
Imaginary friends are actually quite important.
They allow for the child to safely experiment with different emotions such as anger, empathy, and fear. This is a time of life when the three to four year old is looking for some independence, but at the same time is nervous to venture out too far. An imaginary friend allows the child to control the circumstances surrounding play and do the experimenting that is necessary to learn the social skills required for proper interaction with other children. How the child feels and acts with this imaginary friend can sometimes give an idea about his concerns, fears, and interests. For example, the child who comforts his imaginary friend because there is an imaginary dog in the room may be signaling his own fears of dogs.
