Sibling Sex Combinations/Birth Order

[NinetyS3venStars]

I was thinking today about the fact I don't know a family that had a boy first, then a girl, then another boy. I'm sure they exist but I don't know of anyone who's in or has had a BGB birth order/sibling combo.

What would you say are the most and least common combinations?

I'd say I know a of family with 3 of same sex. So GGG, or BBB.

I'm from a BGGG family. I'd say that's quite rare to find nowadays just because people have less children.

5 siblings and we all had BBG

I have cousins who are BBGBB; a friend who is BGB , and the rest of my friends and family are pretty much 2 DC families - some single sex, some one of each.

My biology classes were so long ago that I have no recollection of studying this sort of thing, but I would think each pregnancy starts with an equal chance of either sex? 🤷🏻‍♀️

I have BGBB, so definitely boys can follow girls even if you start with a boy!

GBGB here. 2 Friends have BGG.

BGB....then BBB

I have 5 dc, all boys
