Children increasingly engage with digital tools, necessitating UX evaluation methods suited to their cognitive abilities. This study redesigns the Short User Experience Questionnaire (UEQ-S) to make it more accessible for young users. The new version integrates illustrations, contextualized items, explanatory text, and a sans-serif font to enhance comprehension and engagement. In particular, illustrations are used as a key element to clarify concepts and make the questionnaire more engaging for children. Following a research through design approach, the structure of the validated UEQ-S is maintained while adapting it to children's needs. Although promising, the redesigned tool requires further testing to assess its effectiveness in realworld applications.
