As salamu alaykum,

Thank you for writing in to our live session. You question brought back many memories of my daughters doing that! They also had tea parties with their dolls and talked to them like they were real friends. My son also did this with his action figures. He would line them up and talk to them about a “mission” they were going to be sent on. Soon paper airplanes were flying through the living room and different voices would be chiming in on the action as my son would create voices for his “friends”. All my children had wonderful times such as these and are now well adjusted , intelligent young adults!

What your son is doing is normal. It is called “modeling”. What he is doing is modeling behaviors that he has seen either in school or at home or some other educational setting. In fact, your son is probably very bright as he is able to use his imagination, creativity and real life experiences to keep himself occupied.
As long as your son has friends that he talks to, is expressive at home and is not socially withdrawn, you need not worry about this behavior. It is just normal play for an intelligent and creative young child. Enjoy it while it lasts!
