Book excerpt: This book draws on a wide range of evidence to explore the facts about the relationship between substance misuse and domestic violence and their effect on children, and examines the response of children's services when there are concerns about the safety and welfare of children. It reveals the vulnerability of these children and the extent to which domestic violence, parental alcohol or parental drug misuse impact on children's health and development, affect the adults' capacity to undertake key parenting tasks, and influence the response of wider family and the community. It includes parents' own voices and allows them to explain what help they feel would best support families in similar situations. The authors explore the extent to which current local authority plans, procedures, joint protocols and training support information sharing and collaborative working. Emphasising the importance of an holistic inter-agency approach to assessment, planning and service provision, the authors draw from the findings implications for policy and practice in both children and adult services. This book is essential reading for all professionals working to promote the welfare and wellbeing of children and those working with vulnerable adults, many of whom are parents.
