Parent Advocates provide peer-to-peer support. They come together to help each other and to find a collective voice. Parent Advocates are also working with their allies to bring about policy, programme, and system reform. Many other groups of parents and allies are considering whether to create projects, programmes or organisations to amplify the influence and power of parents in the child welfare system in the UK. This Practice Guide is designed to help parents and their allies in the UK who have created or are in the process of creating a Parent Advocacy programme.
