The use of a Persona Doll in working with preschool children is a relatively new method in upbringing and education. This method was developed by Kay Taus in the fifties of the last century, but education about its application began at the beginning of the 21st century. The Persona Doll is used in work with children with the intention of preventing discrimination and developing a sense of sensitivity to injustice. The goal of this method is to prevent any form of discrimination among children in a way that teaches them to accept and respect differences. This paper provides a brief overview of puppetry as an art, how it relates to the child and how it affects the child's emotional development and creativity. It also states the difference between stage puppets that we have the opportunity to see every day in kindergarten groups and between a Persona Doll. The key difference between these puppets is that a stage puppet is primarily intended for performing on stage, it serves to perform plays and provides the pleasure of creation, while a Persona Doll is used exclusively for educational purposes. She is not a toy doll sitting in the closet waiting for someone to take her out, she is part of the group, an equal member who has her own family, friends, life story and worries that plague most children. The paper describes in detail the process of designing the doll with all the guidelines, the way of applying the doll and several scenarios applicable in practice. Everyday conflicts between children can be solved in an easier way with the help of a Persona Doll. Learning about new cultures, expanding our own and children's perspectives and knowledge, and accepting mutual differences, is what we as educators strive to achieve with our work. Persona Doll is a helper for the teacher and a friend for the children, and through its interesting and entertaining stories, it facilitates mutual communication.
