Book excerpt: This is the updated version of Lets Talk About Child to Parent Violence to recognise that Childhood Challenging, Violent or Aggressive Behaviour (CCVAB) in the home involves more than parents. CCVAB affects everyone in the home, children as well as any other adult. Childhood Challenging Violent or Aggressive behaviour in the home is gaining wider recognition across society leading to an 'opening up' of the lives of families but in the real world little has changed for families. This book is relevant to professionals and parent/carers or those who want to gain a better understanding of Childhood Challenging, Violent or Aggressive Behaviour (CCVAB). CCVAB can be diagnosed as a cognitive disorder identified by the World Health Organisation as a 'Conduct Disorder within the context of the family' yet this diagnosis has not been used for children so far. CCVAB is most usually thought of as Adolescent to Parent Violence and Abuse (APVA) but this overlooks the age when most CCVAB starts - at the age of 6-9 years. For families this means they are left unsupported until children reach adolescence when the behaviour has escalated and become entrenched, something that could have been prevented had earlier recognition been made. Childhood Challenging, Violent or Aggressive Behaviour (CCVAB) is an umbrella term for a range of acronyms previously used to identify children's challenging, violent or aggressive behaviour in the home. Previous acronyms such as CPVA or APVA focus on violence and abuse towards the parent themselves yet evidence repeatedly shows this is not always the case and sibling abuse or property destruction can also happen. We look to open up understanding and highlight how listening to families is the first step of developing support for these families and remove preconceived views about who these families and children are. We consider CCVAB against new information about Adverse Childhood Experiences (ACEs), children with Special Educational Needs or Disability (SEND), Neurological development and Learning Difficulties to bring attention to the many ways that Childhood Challenging, Violent or Aggressive Behaviour can happen. This book looks at what is known and what is emerging to help provide better understanding. the impact on families living with CCVAB is immense, by including parents views these families explain what living with CCVAB is for them in the real world and how little support is available to them and their family
