Children’s voices have not always been solicited in sociology. A transformation was needed in the study of socialization for childhood to be conceived as the underlying thread of analysis. In order for the centrality of childhood to emerge, researchers dedicated their energy in soliciting children’s voices. The paper retraces the emergence and development in the concept of children’s voices, drawing on the work of scholars over a period of thirty years. I will begin by discussing two early issues encountered by researchers: the legitimacy of children’s voice in research and debates on methodology. Children have expressed themselves on an abundance of topics affecting their lives which will always be an important legacy. I then bring up the critiques raised from within the discipline around notions of authenticity and inclusion of children’s voices as well as on feeling legitimated to speak as a child. I conclude with the example of a large-scale research project where voices come alive without children being interviewed directly, the outcome of a focus on voices being to be heard in order to bring changes that are meaningful to children’s lives. Not being heard is being deprived of one’s voice.
