The integration of digital technologies into the play dimension of kindergarten raises profound questions about the role of play in learning and the pedagogical and ethical responsibilities of the teacher. This contribution critically examines the transformations of children's play in the digital age, highlighting both the educational potential and the critical issues arising from the intersection of play and technology in early childhood settings. It proposes digital play education as a self-training opportunity for teachers, through critical tools, reflective practices, and ethical-pedagogical awareness capable of informing educational choices in response to the challenges posed by children's needs and educational goals. Finally, it outlines possible guidelines for a critical and ethical approach to digital play.
