The work is based on the role of a stage puppet in the emotional development of a preschool child. From the very beginning, the doll is a symbol of security and trust for the child. Allows a child to develop his speech and communication, while enriching the child's vocabulary. As the doll can be considered a child's first friend, a child will more easily express their emotions through the doll and increase self-confidence. In this work, the notion of puppetry and stage puppets are explained, while for the practical part of the work I selected a puppet with big mouth as a didactic tool for achieving the goal of this work. The aim of this work is to show the importance of a doll in emotional development. The second part of the work is dedicated to performing a puppet show in kindergarten “Bambi” in Ivanec. The play I performed myself. Stage puppets and the production of stage puppets I designed and made myself, while the text of the play is also my own making. The characters in the play are animals, specifically, a cat, a mouse and a rooster. Kids love animals so I chose just them to attract children’s attention and interest. The play is short, consisting of five scenes, three characters and four songs. A screen at the height of the children was used to perform the play, so that the children could later play with their own puppets. After the play, two workshops were held, drama and art, in which children participated. A play called "What did Frida learn about anger?" provoked different emotions in the child, so, in the end it was possible to claim that the use of puppets is important in kindergarten.
