I think being younger than my ENFJ older brother has made me more introverted. He spoke for me when I was extremely little (or so I'm told), and would often get into loud arguments and discussions with my parents that I would be too scared to join, so I just listened. I don't think having a little sister really contributed though.

Also, credit for my new avatar goes to this person. I found it on the google.
I am the oldest, brother in the middle and step sister youngest. As a child i was more extroverted than at present and my brother was quiet, now he is the life and soul of the party and hates spending time on his own (he needs company at all times, ESTP) and my sister (ESTJ) was a total introvert as a child and now is just as extroverted as my brother.
My oldest son has always been an introvert and my younger kid has moments of both introversion and extroversion depending on his mood.

Wonder if there is a correlation between birth order and introverted or extroverted traits. Feel free to discuss if your birth order has influenced you as an extrovert or an introvert.
I don't think there necessarily is... because I think introversion and extraversion are traits we are simply born with having.
I do think that being an only child made me more introverted though. I was left to my own devices most of the time since both of my parents worked. Lots of time to learn how to entertain myself for many years, and to learn how to adapt to the hermit lifestyle I have come to appreciate so much.
