Key facts
What is the Sibling Peace Plan?
Sibling conflict is common, but frequent hostile conflict can affect children’s wellbeing. Involving children in rule-making, teaching problem-solving and promoting positive shared time can improve sibling relationships.
Why it works
Research highlights skills such as emotion regulation, perspective-taking and conflict management as key to positive sibling relationships (Kramer, 2010). Positive reinforcement and consistent consequences are core parenting strategies (Kazdin, 2005).
