Yes, in most cases, young children with imaginary friends eventually realize that these friends are not real and stop believing in them as they grow older. Imaginary friends are a common part of many children's development, and they can serve several functions, such as companionship, emotional support, and a way to explore their imagination and creativity.
Typically, as children reach school age and their cognitive abilities develop, they start to understand the difference between fantasy and reality. They become more adept at distinguishing between imaginary playmates and real people. This process is a natural part of their cognitive and social development.
While imaginary friends are temporary for most children, they can still play an essential role in their emotional and social development during their early years. These "friends" often help children navigate through various challenges, practice social interactions, and cope with emotions.
It's important to note that not all children have imaginary friends, and those who do may have different experiences with them. Every child's development is unique, and some may continue to engage in imaginative play even as they grow older, even if they fully understand the difference between reality and fantasy. Such creativity and imagination can be healthy and continue to play a positive role in their lives.
