It can catch a parent off guard when a child starts chatting with an empty chair or insists on setting a place at the table for a friend nobody else can see. Some parents worry it might mean their child is turning to an imaginary friend in place of real ones — but the American Academy of Pediatrics (AAP) says this is, for the vast majority of children, a completely normal part of development.
When and Why It Appears
According to the AAP, imaginary friends can appear as early as around two-and-a-half to three years old, and research shows children between ages 3 and 5 are the age group most likely to have one. In a study of children ages 5 to 12, about 28% reported having had an imaginary friend. The AAP explains that playing with an imaginary friend can help build a child’s social, emotional, and coping skills. An imaginary friend gives a child a risk-free space to rehearse social situations before trying them out with real peers — the child can practice social scripts, work through conflicts, and explore different roles without facing the real consequences that come with actual peer interactions.
What’s Helpful to Know as a Parent
Having an imaginary friend isn’t a sign of trouble with peer relationships. If anything, it tends to reflect active imagination and cognitive development, which is a good reason to treat it as a normal developmental stage rather than something to shut down. Showing genuine interest when a child talks about their imaginary friend, or going along with small requests like setting an extra place, is perfectly fine. That said, if a child tries to use the imaginary friend to dodge responsibility for their own actions (“I didn’t do it, my friend did”), it’s worth gently making clear that the child is still responsible for their own behavior.
Common Parent Mistakes
Strongly denying the friend’s existence or scolding a child with “there’s no such thing, stop that” can make a child feel ashamed of their imagination, or push the imaginative play into hiding rather than stopping it. On the other side, letting a child become so absorbed in an imaginary friend that real opportunities to play with peers get neglected isn’t balanced either. The goal is acknowledging the imaginary friend while still making sure time with real peers stays a regular part of the routine.
What Can Differ by Child
Children with fewer siblings or fewer chances to play with peers may be somewhat more likely to develop an imaginary friend, but that doesn’t mean weaker social skills. For some children the imaginary friend fades within a few months; for others it continues to show up over a couple of years — both patterns fall within the normal range.
When to Consider Talking with a Pediatrician
The AAP recommends talking with a pediatrician if other developmental concerns show up alongside the imaginary friend involving speech, talking patterns, or social interaction; if the imaginary friend never seems to go away or appears to be talking constantly; if the imaginary friend is threatening or is encouraging violent behavior; if there’s a sudden change in social interaction, hygiene, speech, or concentration; or if there’s a strong family history of mental illness.
