The Invisible Middle Child

Dr. Alfred Adler, an Austrian psychoanalyst, first brought the effect of birth order to light. He suggested that birth order has a strong affect on a child’s character. Dr. Adler was a middle child himself.

Middle children often feel left out and invisible, a contrast from their older and younger siblings. While older children get the benefits of all of the “firsts” a child accomplishes, younger children benefit from the emotional impact of being the baby of the family, often being spoiled and coddled. Middle children, however, often feel as though they have nothing special that is just “theirs.”
