We don’t get to choose the order we’re born into, but it’s wild how much it can shape who we become. Though birth order may seem like an inconsequential family fun fact, it can influence how we move, love, lead, and even how we see ourselves. Whether you're the dependable oldest, the often-overlooked middle child, the free-spirited baby in the family, or the only child who grew up as their own best friend, there's a chance a few of your core personality traits are tied to the role you played growing up.


Eldest Daughter Syndrome had its viral moment online last year, and for good reason. The term gave language to the silent pressures so many eldest daughters tend to carry as a result of their birth order. Beyond that very needed conversation, birth order as a whole can offer insight into not only our traits and tendencies, but also how we show up in life, love, and even our work.

Below, we’re breaking down the traits most commonly associated with each birth order. Keep reading to learn what your birth order might say about you.

If you are the oldest...

Let's be real, being the firstborn often comes with a lot of responsibility. And it's usually not by choice. From early on, they’re the ones who set the tone, carry the weight, and take on the title of "the responsible one." Because of that, they often grow into reliable, high-achieving adults. But the pressure of being "the blueprint" and the one to "lead by example" can also be a heavy burden to bear.

Oldest child traits may look like:

  • Natural leaders that take charge even when they didn’t mean to (read: she's bossy, but keeping it cute)
  • High standards (for yourself and everyone else)
  • Motivated, goal-oriented, and always chasing that next accomplishment
  • Reliable and conscientious
  • Perfectionist tendencies that can lead to burnout
  • Struggles with being controlling or micromanaging
  • Often cautious, craving stability over spontaneity
  • Finds it hard to rest or ask for help

If you are the middle child...

In the grand scheme of the birth order lineup, the middle child can be the quiet MVPs. As the child who falls in the order "in-between," they’re used to being the one who keeps the peace while also fighting to stand out. But being the “in-between” can also mean feeling overlooked or forgotten. In some families, especially ones with toxic dynamics, the middle child may even take on the role of the "black sheep," while their siblings are seen as the golden children. Still, despite (or maybe because of) that, middle children tend to thrive socially and can read a room like the back of their hand.

Middle child traits may include:

  • Top-tier peacemakers who can smooth over almost any situation
  • Adaptable and easygoing (even when they’re lowkey screaming inside)
  • Often feel overlooked or like they have to do the most to be seen
  • People-pleasers who put everyone else first
  • Social butterflies and community-minded, with strong friendships outside the family
  • Can be rebellious when they feel boxed in
  • Thrive when they’re allowed to define success on their own terms
  • The ultimate go-between, translating vibes between generations, personalities, and moods

If you are the youngest...

The baby of the family walks through life knowing how to charm, persuade, and perform. They often grow up with more freedom and fewer expectations, which fuels their adventurous and carefree side. But that same freedom can sometimes lead to entitlement, or a tendency to seek validation by being the "fun one."

Youngest child traits might include:

  • Social butterflies who light up a room and don’t mind the spotlight
  • Natural charmers, funny, flirtatious, and usually down for anything
  • Can be a little self-centered or attention-seeking (but you still love them for it)
  • Tend to keep things uncomplicated… unless they’re not getting their way
  • Known to be manipulative when trying to get what they want
  • Free-spirited and bold in their choices
  • Often underestimated, but capable of big things when they focus
  • Thrive in spaces that let them express, explore, and be a little extra

If you are the only child...

Only children can be the ultimate "one woman show" as they are often a mix of all the birth orders rolled into one. Without siblings, they learn to entertain themselves, advocate for their needs, and navigate adult conversations early. That independence can make them magnetic, mature, and deeply introspective, but it also comes with a deep craving for validation and control.

Only child traits can include:

  • Mature and wise beyond their years, often viewed as old souls
  • Conscientious and responsible, usually the go-to person in their circle
  • Seek approval and validation more than they let on
  • Natural leaders with big ideas and even bigger plans
  • Can be sensitive and deeply affected by criticism
  • Prefer structure, routines, and control (sometimes to a fault)
  • Like things done their way (and don’t love compromising)
  • Thrive in solitude but still want to feel seen and celebrated

December is about letting go. We end the year with the need for more peace, reflection, and rejuvenation, and that is exactly what December is providing for us. The Sun is in Sagittarius, and anything is possible. This is the month to believe in that and to know that the universe is supporting you. With a Supermoon in Gemini as we begin the month as well, we have an opportunity to gain the closure we have been looking for this year and to wrap up old projects, ideas, and communication breakthroughs.

This is the month to make your peace the priority and let go of trying to control the way the tides are turning. Trust in your new beginning, and give yourself time to prepare for it this month.

Melatonin Is Linked To Serious Heart Issues. What To Know.

I already know that this one is gonna hurt a few feelings. The reason why I say that is because, if there is one thing that (many) folks are going to take if they are looking to get a good night’s rest, it’s melatonin, chile.

How do I know? Well, aside from the fact that some people in my own world are hooked on it, it’s also been reported that as many as 27 percent of Americans rely on this particular supplement to catch themselves some nightly zzz’s. That’s why, when I peeped that a particular study about melatonin was damn near viral, I decided that I absolutely needed to use my side of cyberspace to get the word out.
