• Sibling relationships can have a protective effect on mental health, according to psychologist Traversmark. Engaging in "sibling revelry" - playful, competitive, and affectionate interactions with siblings - can foster resilience, emotional regulation, and a sense of belonging. These dynamics can help siblings navigate challenges and build coping strategies that serve them well into adulthood.

• The article highlights three main protective powers of sibling revelry. First, it can promote emotional regulation by giving siblings a safe space to express and manage intense feelings. Second, it can build resilience by exposing siblings to manageable stressors and teaching them to problem-solve. Third, it can provide a sense of belonging and identity, which are crucial for healthy development.

• Psychologist Traversmark emphasizes that while sibling relationships have their ups and downs, the overall benefits of sibling revelry outweigh the challenges. He encourages parents to foster these interactions and not try to eliminate all sibling conflicts, as long as they remain within healthy bounds. By embracing sibling revelry, families can cultivate lifelong protective factors for their children.
