This book reflects the desire to highlight the trajectories of teachers and to demonstrate, in dialogue with these subjects, that teaching in Early Childhood Education involves dimensions that escape scientific objectivity and tension the discourse of technical rationality that permeates many discussions in the field of the teaching profession. Affections, relationships, care, values, aesthetics, commitment, the moral and ethical dimension of the work of teachers of babies and young children help to make up ways of being in the teaching profession and should not be considered unprofessional elements, as can be inferred from the narratives discussed throughout the chapters.
