One big brother, five years older.
I’m the middle child of five.
belladonna: your folks just couln’t win for losing, huh? 
One brother, five 1/2 years younger.
There are seven of us (me and six siblings), which most people think of as being a large family, but I knew three families with 14 kids when I was growing up so I’ve never thought of our family as being particularly large.
One – the bestest kid sister a fella could ever be so lucky to have!
Heh - that sounds like my family. Five girls in 10 years - at least the last one wasn’t twins. Well, my oldest two sisters and youngest two sisters were born less than a year apart, so Irish twins, I guess. Except we’re not Irish or Catholic.
One brother, 8 years older.
5 siblings - I am second of 6. Older brother, younger sister, brother, sister, sister.
Although I have no kids, between my 3 brothers I have 15 nieces & nephews, all from first marriages (no steps or halfs).
I used to call them the Stepford brothers because all three of their wives had overlapping pregnancies the first 3 rounds. Since my 3 older brothers were Irish triplets (1 brother, then 10 months later twin brothers) - they have always been competitive. But that seemed kind of ridiculous to me.
The youngest brother has 7 kids - 1 girl, 1 boy, girl, girl, twin girls, girl. They don’t even have the excuse they were trying for a boy. My SIL was FB a few months ago bemoaning that her baby just turned six and she was considering having another one. Then she re-posted that she would just wait impatiently for grandbabies. This squicked me out, her oldest daughter just graduated high school last year.
I have one older sister. There is a small part of me that thinks there was another kid that was delivered to my mother. My sister’s birth certificate said that Mom had a prior delivery and my birth certificate says that there were two prior deliveries. Mom (and anyone in her family that would know) are all dead now and my father denies it. But that is something that he would not tell me.
I have (or had) eight siblings, for a total of nine kids in the family, seven boys, two girls.
I was the second youngest, and the baby of the family for almost eight years until my younger brother came along. All from the same parents. My folks definitely liked kids.
All grew to adulthood, but we’ve lost three in the last five years. Still, I always think of us as nine.
I didn’t count step-brothers. My Dad has remarried twice, and both wives had three sons. I never considered them “brothers” as we were all adults when they married. In fact, I can barely remember their names, and I definitely don’t know their wives and kids names.
Two brothers, both younger than me. I know there were quite a few miscarriages both before me and between me and #2.
Four altogether - Two half-brothers, a half-sister, and an adopted sister.
Oldest brother (42), second oldest brother (39), adopted sister (35), me (32), half-sister (18). All halves from same parent. I haven’t seen my adopted sister in 18 years but would like to.
Six. 3 older brothers, 1 older sister, 2 younger sisters. I have 6 steps but I don’t count them because we were all pretty much adults when my dad got remarried. I’m not sure I could remember all their names.
One younger brother, now deceased. We were 18 months apart.
Only children, unite!
i had nine, only 3 left!
