“Oldest child syndrome,” also known as “firstborn syndrome,” refers to the unique traits and experiences often associated with being the first-born child in a family. These individuals tend to be responsible, ambitious, and driven, often taking on leadership roles both within the family and in their broader lives. Key characteristics include a strong sense of responsibility, a drive for perfection, and a tendency to strive to meet high expectations. Understanding these traits can help both parents and oldest children navigate the challenges and opportunities that come with this birth order dynamic.
