This paper focuses on the challenges digital ethnography faces when analyzing specific mobile mediated
everyday practices that are part of children and youth cultures. The use of digital tools requires
transforming research activities from a double perspective. Firstly, because children and adolescent
practices are mediated by mobile communication tools that allow them to participate in online environments
combined with their everyday offline scenarios. Secondly, the Internet and other digital technologies
provide new analytical tools that interact with developmental and literacy theories and even transform the
basic principles of traditional methodologies such as ethnography. We explore the methodological
challenges taking our own research as an example. We focus on eleven workshops which took place in a
community center and more specifically on Nadia, one of the nine-year-old girls who participated on those
workshops. Focusing on the use of multimodal discourses we adopt the concepts of internal and external
grammars of digital discourses and adopt several units of analysis (from macro to micro perspectives) to
explore those.
