First of five.
I’m the oldest of five. The first four are boys, and the youngest a girl.
Okay…are you concentrating?
My mother adopted four kids. One oldest girl, a set of “twins” that were from different families, but only nine days apart, and a younger girl. The girl from the “twins” got pregnant at 18, and my mother adopted that baby as her own. That was me, making my bio-mom my sister, and my semi-bio-grandmother my mother. My bio-mom married my bio-dad and had two other children, a girl and a boy, then had another girl with another man. Then when I was 13, we got a foster brother who was older (18ish).
I have no idea where I am in birth order.
Youngest of 3. The only son. My 2 sisters are 4 and 5 years older. Same parents.
Eldest of 3.
Wife is eldest of 2.
Just for kicks, my father was the youngest of 3, and my mother was the eldest of 8.
Seventh son of a seventh son.
Oldest of two. Only girl.
I’m another one who never knows quite how to answer this question. Effectively, I"m an oldest child. But…
Until the age of 8, I was the 4th of 5. Big brother, big sister, big brother, 14 year gap, me, little sister one year younger. I was treated more like the older of 2 than the 4th of 5, though, given the big age gap.
Then, at age 8, one day out of the blue Big Sister came to me and explained that actually, she was my mother, Mama was my grandmother, Grandma was my great-grandmother, little sister was my aunt, big brothers were my uncles, little nephew (her son) was my half-brother (are you keeping all this straight), my daddy was someone we didn’t talk about, and from then on I was going to live with her and her husband and son. (I had like one day to adjust to the idea.) My half-brother was 6 years younger, so in that family setup I was the oldest of 2.
I definately have the personality traits of an oldest, and of a “caretaker child”.
Yeah, yours is complicated. I have no idea where you are in the birth order, either.
I’m the second of three daughters. My father had two sons, by two different mothers, before my sisters and I were born. However, I wasn’t even aware of their existence until I was in my teens, so I wouldn’t really count them in something like this.
I’m the baby, 3rd of three.
But from age 9 onward, I was an only child; my sister got married and my brother joined the Navy.
Im the youngest of three. My sister was born 1979, my brother was born 1983 and died aged 10 months and then theres me born 1985. So Im the baby of the family. 
My parents were married in 1958, and celebrated their fiftieth anniversary in July.
I came along in '59, followed by a sister in '61, a brother in '63, and another brother in '65. All of us are still alive, and there are no adopted or half-siblings in the mix.
Each of my parents is the oldest “child” of three. Dad’s sisters were born 7 and 14 years after he was, while Mom is three years her brother’s senior as well as seven years older than her sister.
I’m the fifth of five, though I feel like an only child - my sisters ranged in age from 10 to 17 when I was born, and they all moved out young, so I was the only child living with my parents from 4 on.
Eldest of two daughters.
Oldest of two boys. Oldest grandson, second oldest grandchild.
Depends on how you look at it.
I’m my dad’s only biological child.
I’m my mom’s third of four biological children.
My mom and dad adopted a girl before I was born.
So assuming that all siblings are equal …
I’m #4 of 5.
