Emerging research on children who live with a parent with an Acquired Brain Injury (ABI) shows that these children don’t talk about their lives and the daily challenges they experience. Furthermore, children are not asked about their experience by adults who know them, and those who have been asked limit what they disclose because they feel no one understands. This self-censuring has implications for what can be found about children's experience of a parent with an ABI and leads one to question the validity of what has been discovered so far. Applying the findings of her research, and research from a variety of other marginalised and silenced childhoods, along with her own lived experience, Sheridan posits a complex, in-depth and compassionate exploration of how the control of knowledge creates behaviour that overlooks other types of information, preventing other ways of living from becoming known and normal. Combining real-life stories with rigorous academic research, Sheridan weaves a genuine account of why children don't talk, because, good intentions aside, it is simply not enough to rely on what we (think we) know to support a child. One must proactively create the conditions for a child to talk. Listen Up provides valuable insights and a practical method for how to identify a silenced child and how to talk to them so that they can speak. Vital reading for anyone with children or working with children, particularly those who feel different.
