The topic of the thesis is the influence of the doll on speech and language development. Often are children attached to their dolls-first toys. We can see this best when enrolling in kindergarten, i.e. during the adaptations period when children hold their dolls tightly in crises, and often turn to them because they feel safe in communicating with dolls. The doll in the kindergarten aims to familiarize the child with with new content, but also encourage him to use new words. Today, we are witnessing that children start speaking later and later, and we are invited to encourage the development of the child's speech in all ways. Once the doll becomes part of the group, it becomes a powerful tool with which educators communicate with children and can bring any situation closer to them through a doll. The doll helps children in their development and vocabulary enrichment, introducing new words. It contributes to the development of a positive self-image and strengthening confidence.For the purpose of writing this, a project was done, goal of which was to show the benefits of working with dolls that help children develop speech. The chosen story was "Kolibica" as a continuation of the eTwinning project "Životinjsko carstvo" in which the children were included last year, and therefore the topic related to animals is very close to them. Idea behind it is to show different activities that include all phases of the project, from preparation to central activities and include a doll as a means of encouraging the development of speech and language communication of early and preschool age children, included in the project. During the project, children were offered different types of dolls to develop their own interests in the best direction. The activity was carried out in the educational group "Vrap i " DV Sesvete. The children are 3 to 4 years old.
