This chapter discusses how to involve children and young people in decisions and encourage them to express their needs and participate in the decision-making process to develop a quality intervention. By describing the different aspects of projects involving a participatory approach, it shows how giving voice to children and young people unlocked new perspectives regarding the Hungarian child protection system. Participation of children in research is limited in Hungary, partly due to the challenging legislation and authorisation process. This chapter shows how research to develop child-friendly digital tools can contribute to collecting children's views on their needs related to child protection support, and how the process of listening to children can improve parenting and caregiving responses to the needs of younger and older children living with their families or in the child protection system. The chapter analyses the effect of digital applications on children's and young people's capacity to advance towards autonomy, including applications and a video campaign with short video clips created by young people. These projects gave an opportunity for children and youth in the public care system to describe their lives and wishes for the future. The analysis found: (a) for a functional child protection system and to promote development for children and young people, children's voices need to be amplified; (b) by expressing their voices, children become more autonomous; (c) children's voices contribute to decreasing social prejudices against children and young people in public care; and (d) listening to children and youth
