When your children are born close in age, you may expect them to have a lot in common. While there is so much research on how birth order and sibling relationships shape personality development as our little ones grow, there's far less research on how siblings actually share similarities. I mean, the traits siblings close in age share has to go beyond just being around the same age, right?
An article featured in Psychology Today dove into each sibling's role and how it may impact their personality. For example, "The firstborn child basks in her parents' undivided love and attention for a period of time, and often benefits emotionally from this experience. She can emerge feeling loved with a sense of security and self-confidence. This will help her to go out into the world and become a responsible leader." While the secondborn will face their own unique advantages and challenges: "The secondborn child benefits from calmer, more self-confident parents and enjoys special attention as the baby. He also has the advantage of learning from, and modeling, his idolized older sibling. As a result, he may be able to read at an earlier age." (Do we even have to mention middle children? Just kidding... kind of.) But while birth order may make a difference in personality, there are some unique traits that children born close in age may share as well.
