This book is the result of doctoral research aimed at understanding the conditions of possibility that have established the exercise of governing practices between children and adults, referred to here as INFANTOCRACY. With the eye of a cartographer researcher, we selected and analyzed everyday situations that showed shifts in the exercise of governance between children and adults in contemporary times. These practices trigger the formation of flexible, healthy, self-managing, proactive subjects, which are necessary characteristics of subjects of neoliberal rationality. Infantocratic practices constitute a shift in the ways of understanding and living the relationships between children and adults in contemporary times, producing new ways of being a child subject.
