Getty ImagesBack in the '70s, the most common family unit had four kids or more, according to New York Magazine. Today, nearly two-thirds of women with children only have one or two. As the median family size continues to decrease, middle children will increasingly become a rare breed.

3More than half of U.S. presidents were middle children.

Getty ImagesYou can also cite Bill Gates, Madonna, Elena Kagan, Nelson Mandela, Susan B. Anthony, Walt Disney, Charlotte and Emily Brontë, Martin Luther King Jr., and Michael Jordan as successful middles. But we should appoint Jennifer Garner as our celeb spokeswoman: "I am the model middle child," she once told Parade. "I am patient, and I like to take care of everyone. Being called nice is a compliment. It’s not a boring way to describe me." We're with you, Jen.

5There's an official middle child wine.

CBS Photo Archive//Getty ImagesYou've probably heard of "middle child syndrome," a theory initially posited by Austrian psychologist Alfred Adler in the early 20th century. The gist is that middleborns feel left out and resentful as they don't receive the same privileges as the oldest or the pampering of the youngest. However, scientific research has yet to provide much evidence that this is true.

7Middles apparently don't act anything like the oldest.
Getty ImagesAnother philosophy as to why middles are the way that they are: "Once a role is filled by the firstborn, the secondborn will seek out a role that's completely the opposite," Kevin Leman, Ph.D., author of The Birth Order Book, told Parents. This helps account for why some middles act out while others love to please — or it could just be because we're our own people, you know?

8Some middles aren't really "middles" per se.
Nicholas Hunt//Getty ImagesResearchers who study birth order consider any sibling not the youngest or oldest a middle (even if you're, say, second out of five kids and not exactly in the middle). However, there's also something called a "functional firstborn." For example, if your parents had another child 10 years after you were born (like Britney Spears), you still spent most of your childhood as the "youngest" and may exhibit some of the traits most associated with the baby of the family.

9Our biggest strength: We're the peacemakers.
NBC//Getty ImagesIt's not all bad when it comes to middle child stereotypes. Adler and other contemporary psychologists believe that our "middleness" actually helps us develop skills like diplomacy, resilience, and independence. Adler also thought that the lack of parental attention made middleborns more likely to fight injustice. Right on.

10And we're underestimated, according to one expert.
Karwai Tang//Getty ImagesFor all those reasons, some experts believe middles are uniquely equipped to take on big issues. "What few people realize is that middle children are actually more likely to successfully effect change in the world than any other birth order," Salmon told New York Magazine. "As is so often the case with middles, they’re perennially underestimated."

13The best sibling bands all have middles.
Hulton Archive//Getty ImagesFamily acts like Haim, Hanson, The Band Perry, The Osmonds, The Beach Boys, and even the Jonas Brothers wouldn't be the same without the middle child. In fact, all three members of the Bee Gees — Barry, Robin, and Maurice Gibb — were the middle of five kids. And they're one of the best-selling musical groups of all time.

15But that birth order stuff could be overblown.
Getty ImagesEven if we want to claim middle-child kinship, there's still a lot of controversy over how much birth order affects personality, if at all. The traits attributed to each family member can seem so "spot-on" because of something called the Barnum Effect: a psychological phenomenon where seemingly specific personality descriptions are actually vague enough to apply to a lot of people. The same concept is what makes horoscopes and fortune telling seem "accurate."
