Enabling children and young people to understand, identify and raise their safety concerns with a trusted adult and within safe organisations is vital. However, there is little advice provided to adults and institutions about how this might be done in child-centred and child-informed ways. Drawing from the Children's Safety Study, a study that considered children's perceptions of safety, their safety needs and how well they believed adults and institutions protected them from harm, this paper provides practical guidance based on what children and young people have said themselves, as well as observations about how this might be put into practice. Also included in this paper is a description of some tools successfully used to talk to children and young people about their safety, and some ways that adults and institutions can respond.
