Firstborns are the first children born to their parents. They often take on leadership roles within the family and may feel a sense of responsibility for their younger siblings. Research suggests that firstborns tend to be more conscientious and achievement-oriented compared to their siblings. In many families, firstborns experience different parenting styles, as parents may be more cautious and attentive with their first child. This can lead to firstborns developing strong organizational skills and a desire for approval. They may also face pressure to set a good example for their siblings, which can influence their personality and behavior throughout life.
