Children are not only willing, but actively wishing to engage in play with dolls and figures. This presents an opportunity for parents; Playing with action figures can have many benefits to a child's development. It requires an active imagination. 
Creative or imaginary play is an important aspect of play that should be encouraged where possible; As action figures cannot talk for themselves, children must give them a voice. This prompts the child to develop the skills to act in role as a character. Also, they must learn the skills to develop the drama out of role, in order to shape the storyline.
Children should drive the narrative of this creative play, while the adult should react in an encouraging and positive manner. Enthusiasm and support for the child's creativity helps foster an active imagination and self-steam.
