The child expresses himself in the game by speaking through the doll from an early age, the influence of the doll on the child's speech expression has a positive and strong influence, helping the child to free himself and speak and share what is bothering him, how he feels at a given moment. It helps the child to develop a vocabulary and a rich vocabulary. The paper explains the concept of puppetry and the types of puppets, while for the practical part a yawning stage puppet was chosen as a mediator in communication and speech expression. The aim of the paper is to show the importance of stage puppets in stimulating speech expression of children of early and preschool age. The second part of the work is devoted to the performance of a puppet show in the kindergarten "Vrbovec" in Vrbovec. The performance of the play took place in the "Ružice" educational group, where I performed the play independently with the personal creation of a mouse puppet and a mushroom stick puppet. The performance lasted 5 minutes, consisted of one scene. To perform the play, a screen was used at the height of the children so that the children could also use the screen to perform their own play. The play caused a positive reaction among the children and encouraged them to create their own play. The use of dolls by a child helps children to express themselves more easily in front of other peers or the environment.
