Interesting trend that the first two being boys leads the first two being girls by about 2 to 1 (31 to 16 right now).
I’m the middle of three girls.
Mom–middle kid, older brother, younger brother
Dad–middle kid, older sister, younger brother.
I answered for me and my siblings (two girls, then a boy, then another girl-- I’m that last girl). My mom is the oldest of four, three girls then a boy. My father is the middle child, with an older brother and a younger sister. My husband has two older brothers. That’s all I can think of that fit the pattern you’re talking about, and two have the third child being different than the first two, and two have the third child the same. Go fig.
Hey, I found something on this:
The Odds of Having a Boy or a Girl
First two are boys – Odds are 53.3% the third will be a boy, vs 46.7%
it will be a girl
First two are girls – Odds are 54.0% the third will be a girl, vs
46.0% it will be a boy
Thus, there is a shift from the usual pattern of births, which is 51%
boys, 49% girls. The shift is fairly small, but noticeable just the
same.
Me: 4 boys
My brother: 4 girls
My sister: 1 of each
My parents: 2 of each (FMFM) (Note: eldest sister did not procreate)
My wife’s parents: 5 of each (yes, 10 kids)
My grandparents: 3 of each…on both sides…hmmmm
My family:
five girls, same father and mother
My husband’s family:
Three boys, same father and mother
One girl, same father and mother (different father from the first three boys)
Then two boys from the same father and mother (one of those boys grew up to be my husband)
Me and my hubby:
One girl in 1987
One girl in 1991
Decided we had enough children
In 1997 he decided we could try “one more time for a boy”.
mudgirl was born in 1999, on Dec 29th, just a couple of days before ‘Y2K’
So for us, three girls.
So, grand total:
His mother: five boys, one girl
His father: two boys, one girl
My mother and father:
Five girls
Hubby and I:
Three girls
Now, to further feed your statistics (whatever they may be):
My oldest sister and her husband:
Two girls
Second oldest sister
Two girls
Third oldest sister:
One girl
One boy
Fourth oldest sister:
One boy
Do what you will with that data.
My mother has four sisters. There was a stillborn brother.
One aunt has three boys.
Another aunt had four boys.
Third aunt has a boy and a girl.
My mother has one boy and one girl.
Of my cousins, they have in order:
First cousin: M, F, M.
Another cousin: one boy.
Yet another cousin, brother of the above: a girl.
