Sibling sexual harm and sexually harmful behaviours by children within families

When children and young people have displayed problematic and harmful sexual behaviour towards a sibling or other family member, it can have profound impacts on everyone involved.

Balancing safety, support and recovery for all

Sibling sexual harm, and other forms of harmful sexual behaviour displayed by children and young people within families, creates unique and complex emotional and practical challenges for children, parents and carers.

Parents and carers often describe the discovery or disclosure of a child sexually harming another family member as a crisis point that brings distress, uncertainty and significant disruption to family life.

They may feel torn between supporting the child who has been harmed and the child who has displayed harmful sexual behaviour, while also trying to support other family members – especially other children – and maintain safety for all.

In the weeks, months and years that follow, families may need ongoing support to understand what has happened, strengthen safety, address underlying factors, navigate changes to routines and living arrangements, and repair sibling and family relationships.

Responses that keep the safety and wellbeing of the whole family in view are better placed to support recovery and long-term family healing.
