I was recently listening to a parenting podcast, and they had an episode on birth order. This type of thing fascinates me!
Birth Order Episode 1 // Birth Order Episode 2
In case you aren’t familiar with birth order, here is what ChatGPT gave me as a basic breakdown for birth order basics:
First-Born Children
- Often responsible and reliable
- Tend to be leaders or take charge easily
- Achievement-oriented; may feel pressure to succeed
- More likely to follow rules and respect authority
- Can be perfectionistic or hard on themselves
- Sometimes described as “old souls” or mature for their age
Middle Children
- Often flexible, adaptable, and diplomatic
- Skilled at compromise and seeing multiple perspectives
- May feel overlooked or “sandwiched,” which can drive independence
- Strong peer relationships; value friendships deeply
- Can be people-pleasers or peacekeepers
- Sometimes rebel quietly or carve out a unique identity
Youngest (Last-Born) Children
- Often outgoing, charming, and social
- More likely to take risks or try unconventional paths
- Can be creative and humorous
- Used to attention and may enjoy being the “baby”
- Sometimes less responsible early on (others have done things for them)
- Can develop strong confidence—or depend on others more
Now, I find that fascinating enough. Given the fact that every single person is unique and has a unique personality, its amazing to me that there can be so many similarities just based on birth order.
If you dive a little bit deeper into birth order, there are some other interesting factors to consider. Like age gaps- the birth order experts say that if there is an age gap over 5+ years, it often seems to reset the birth order- so two siblings that are born 8 years apart may both behave like “first borns”.
I’m also so interested in what happens with big families. Let’s say a family has 6 or 7 kids- do the 5 middle kids all behave like middle children? Again, according to the people who do this type of research for a living, the birth order kind of seems to separate and repeat itself somewhere in the mix of kiddos.
And then don’t even get me started on if twins are in the mix!
Does anyone else find this so interesting, or just me?
Thinking about this got me reflecting on my own family- both my family of origin, Theo’s family of origin and our own little nuclear family.
I’m child 2 of 2- so I’m technically the baby/youngest of the family. I do have quite a few tendencies of a youngest child- outgoing, creative, depend on others whenever I can- although I am not irresponsible or unreliable, and I don’t feel like I act like a baby very often lol.

Theo is child 6 of 7- his circumstances are extra unique in that he was 6 of 6 for 6 full years before #7 came along. And his younger brother has special needs so that was a whole different factor to consider. So in many ways, Theo was raised as the youngest of his group of brothers. And yet- he does not have ANY tendencies of a youngest. He is reliable, responsible, in leadership, perfectionistic, and extremely mature for his age- all tendencies of an oldest child!

Then I think about our family- the kids are still pretty young, so they are still developing their personalities- but I see some birth order tendencies and some characteristics that are not at all. For example- my oldest is helpful and reliable, but she isn’t overly organized and not highly achievement oriented. My two middle boys do not show a ton of tendencies for middle child, but maybe that is a very middle child thing to say haha? And then there is our youngest who hits basically every bullet point of a “youngest child” that there is. He’s the baby through and through 😉

So, I’d love to hear it- what is your birth order? Do you fit the stereotypical characteristics of your birth order? What about your kids? Have you noticed any tendencies toward the birth order characteristics, or not?

I do find birth order interesting! I am 3 of 4 and I have both first born and middle child tendencies. My husband has an interesting situation in that his parents divorced and remarried pretty quickly so he went from the baby (youngest of 2), to having a younger stepsister and then a half brother who came along when my husband was 11 so he mostly fits everything with being a middle child. Our firstborn doesn’t seem to fit the firstborn except that he is definitely a leader. Our second totally fits the middle and our youngest fits too except she is responsible.
I think I’m a pretty typical middle child. But there is also that five year gap between me and my brother, so I probably have some first child characteristics. And then my sister is only 14 months younger and everyone thought we were twins….
As a psychology major I actually wrote a paper (or 2!) on birth order in high school and college! I am much like Megan’s husband; my parents divorced when I was real young and then remarried so I have younger 1/2 siblings.. I have aspects of all since my dad never had any other kids I was always treated like the baby of the family by him and his mother and that side of the family but as he only had partial custody and I grew up with 2 younger siblings I mostly have characteristics of a first born. And yet I am a middle child and while I don’t think I have many of those characteristics anymore I can definitely look back particularly at those middle school years and see I was crying out for attention and quietly rebelled a lot. Yet the peacekeeper in me made me feel so guilty for it. To this day I can see and advocate for both sides in nearly any argument.. so yeah I’m a healthy dose of all 3.
