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. Children and young people value being helped to better understand risks and to make better judgements on when to trust and when to be wary. Because children and young people understand and experience safety differently from adults, adults and organisations need to understand what safety means to kids and act to respond to their fears. Including children in the development of strategies and responses for their own safety results in a greater likelihood that children will utilise and feel positive about them. Children and young people want organisations to provide safe physical environments: places that are bright and cheerful, where kids are able to move around, to play and to "hang out" with friends and people they trust. For children's participation to be successful it needs to be supported by the whole organisation, and dialogue about safety needs to be ongoing and built into as many interactions between adults and children as possible. Children and young adults need adults and peers they can trust, and these adults must be accessible, physically present and available when needed. Raising concerns with an adult can be difficult, potentially embarrassing, shameful or uncomfortable. Adults need to respond respectfully and in ways that allay children's fears and discomfort.
