How Can Birth Order Shape Your Personality? True Or Not

How Can Birth Order Shape Your Personality?

You must have heard from someone that the oldest kid in a family tends to be very responsible, while children who have no siblings are far more likely to be selfish and demanding. Are these merely stereotypes, or is it really true that our birth order can shape our personality?

Today we at ToysByAges have decided to find the answer to this intriguing question.

The birth order theory began in the late 1920s with Alfred Adler, Sigmund Freud’s friend and colleague. Adler believed that the order in which you are born into a family inherently affects your personality.


  • Great article!
    I am the oldest sibling in my family but my sister (three years younger) has a higher IQ than I do… so I guess it really depends on many aspects except the order of birth. But in total I think begin the oldest is the best 😉 – never tried something else…

  • You have some amazing information on your site! You can tell a lot of research and in site have been applied here. I had the only child and most of it is true….funny how we were all created different and individual. I’m just waiting for the Grand kids and this site is perfect!

    I have always wondered about birth order theories. This one seems true for me and my siblings. I am the oldest and some of those personality traits definitely fit me. Thank you for sharing!

  • First borns are the smartest for sure hehehe…we have to be, we’re the testers for the parents! Subsequent borns are more independent because they’re allowed to do the things first borns are at an earlier age, usually at the same time as the first born (which is very annoying when you have to wait till your 16 to do something, but next born can do it with you when they’re 14!). Younger borns also have the advantage of learning from watching the older ones doing something, and that sibling rivalry can often bring out their competitive nature which can make them more determined and confident. These are my observations of not only my brother and I, but also of my own children. I guess throwing step children into the mix could shake up things too. It certainly is and very interesting topic, thanks for sharing!

  • I’m a first born and most of it is true but I also agree with u that the child’s upbringing also plays a very important role in shaping a child’s character. My mom was very strict and a great disciplinarian and I wouldn’t be half the woman I am if it wasn’t for her guidance. Thank you so much for such great insight Efi.
