By focusing on a collective aesthetics based on sensation and affect, researchers, especially in Stockholm, Sweden, are exploring a pedagogy that opens up space for assemblages of desire, acknowledging the expressions of children who transform themselves and their milieus into a weave of bodies, spaces, signs and media. By analysing this pedagogy, against the background of the theories of Henri Wallon and Gilles Deleuze and Félix Guattari, I wish to investigate the concept of a "thinner skin mentality". This willingness to transgress one's own stabilising attitude, to move towards a greater sensitivity to relational and situational affectivity when accompanying the learning of children, may provide a point of reference for a preschool teacher qualification.
