Three. A younger sister, an older brother, and an older sister. Ranging within a six year radius.
I mean “range” not “radius”.
I’m the youngest of 3. My folks kept having kids until they got it right. 
I have two siblings.
Two half-brothers and one half-sister, all from my dad’s first marriage. They range from 26.5 to 30.5 years older than me.
One older sister.
There are six of us all together. All daughters.
The youngest–mom and dad’s final attempt at a son–are twin girls.
Oops
3 big brothers
I have two sisters (I am female), 5 and 7 years younger than me. Same parents.
Apparently, I have two.
One is my half sister who is 11 years younger than I am. We grew up in the same house.
The other is a sister who I never met that my Mom gave up for adoption. I can’t recall if she’s older or younger. I only learned this in the past year. Family secrets suck.
I have 6: 3 older brothers, one adopted younger sister who has passed, and 2 younger step-brothers that the 3 older brothers refuse to acknowledge.
The interesting thing is that on the one hand i’m the ‘baby’ of the family. One the other hand, i’m the ‘big sister.’
It’s kind of neat.
One younger brother.
3 sisters. One older, two younger. (And they’re all pretty fucking awesome. Very close we are. [I am a dude])
Two older sisters and three older brothers.
Brother, 10 years older; half-sister, 16 years younger. Also 3 stepbrothers and 1 stepsister but they were already adults when I met them so I don’t count 'em.
Two brothers; one 2 years older, the other three years younger. I was the spoiled only girl-child…
One brother who’s two years older than I am.
One brother, 3 years younger than I am.
4, 3 brothers and one sister, all older with the oldest being 12 years older. I am almost half a century old and I will always be the baby.
There should be an option for “It’s Complicated.”
From my mother and father’s union with each other, I am an only child.
Mom remarried; stepdad had two kids from previous marriage. They also had a baby boy. So that means that on my mom’s side I have a half and two steps.
Dad remarried; he and his wife had a baby girl. Dad remarried again; his third wife had two kids from a previous marriage. So that means that on my dad’s side I have a half and two steps.
Either none or two. I was an only child, but acquired two step-brothers ( one my age, one two years older ) fairly early, though we didn’t actually live in the same house until I had hit eighth grade. But since their kids call me “uncle”, I guess they qualify ;).
