Early and preschool age are phases in a child's life that are characterized by accelerated growth and development of the child's entire being. In order for a child to develop properly in terms of the speech-language aspect, certain conditions must be met, and the pace of its development will take place under the influence of numerous factors, such as genetics, the child's temperament, the environment and incentives. Encouraging a child's language development should be done correctly and in a timely manner because children develop and progress mentally and physically very quickly. Therefore, it is important to carefully consider the child's needs and interests. The child will begin to learn about speech through listening and imitation. Exposure to picture books in children encourages the development of thinking, observation, verbal expression, the development of imagination and aesthetic attitudes. Picture books engage children in different levels of interaction, where the relationship between pictures and text is close. Through picture books, the child comes across unusual phenomena, thinks about them and develops his imagination. Through the speech-language function of picture books, the development of phonemic and phonological awareness is encouraged and supported. In addition, morphological and syntactic development develops in children, they acquire a rich vocabulary, the child gets to know the characteristics of the text and its ways of functioning. Children transfer what they learn visually in the picture book into a spoken expression, describing what they see, describing the content and asking questions about the content, characters, phenomena and ideas. With its text, the picture book should influence the enrichment of the lexical inventory, which will make it easier for children to articulate their thoughts, attitudes and feelings. Reading a picture book should not be a monologue of an adult, i.e. the person reading, but children should be asked questions about what they see, what is shown in the pictures and illustrations. Such questions are incentives for the further development of communication and for the development of children's speech. Language development will be affected by all the texts that children are exposed to, which are adequate to the child's understanding and agree with his interests.
