Siblings are two or more individuals who share a parent in common. They are referred to as brothers or sisters depending on gender. When it comes to child development, sibling relationships can be incredibly important. Siblings represent a child’s first social network, and these early relationships provide a training ground for social learning and relationship building. Because of the intimate nature of these relationships, conflict is almost inevitable. Qualified family therapists and other mental health professionals can help individuals work through sibiling issues and other family-related challenges.
