This study was carried out to examine picture books prepared for children in the 3-6 age group in terms of supporting emotion regulation skills. The sample group of the study consists of 113 domestic or translated children's picture books published in Türkiye between 2010 and 2022, selected using the criterion sampling method. The data were obtained by using the "Book Colophon Form" and the "Criteria List of Coping Strategies with Emotions". According to the study's findings, most of the books analyzed were translated. When the publishing years of 113 children's picture books were examined, it was found that the themes of emotions and coping with emotions were largely covered in 2019. Also, the majority of the children's picture books examined had animal characters. In the books, it was determined that functional strategies such as self-motivation, getting adult support, diverting the mind/attention, and calming down were mainly used to cope with positive and negative emotions. The findings were discussed in the context of coping strategies with emotions and emotion regulation skills in the preschool period.
