3 kids - gender stats probability

133 replies

Blackcoffeeandbiscuits · 08/12/2023 13:29

I read in a few threads that the 3rd kid is most likely to be whatever the 2nd was.

So, if you had G-B then the third will be B
If you had B-G then another G is to follow
If you had G-G chances are that the third will be G, same as if you got B-B you will most likely get another B.

I know in theory each time the chances are 50-50 but this is what research/stats have said.

Is it true though? Let's find out!

AIBU - You have GBG or BGB or BBG or GGB
AINBU - You have GBB or BGG or BBB or GGG

Sister has GBG

I don’t have 3 DC but this doesn’t sound right to me. I think boys are conceived closer to ovulation, as a rule of thumb?

AhBiscuits · 08/12/2023 13:36

And male pilots have more DD because for some reason they have lazy sperm

MilkChocolateCookie · 08/12/2023 13:36

I have BGB

Cindy1802 · 08/12/2023 13:37

Following with interest... BB so far for me (lost the 2nd) but I'm 40 weeks pregnant with the 3rd and don't know what we're having!

OutOfMyDepth86 · 08/12/2023 13:37

GBG here

Headaching · 08/12/2023 13:37

BGB

Bloatstoat · 08/12/2023 13:37

I have B G G so follow the research.

But I'm the eldest of 3 GGB, and my sister had B G B, so my tiny family sample suggests the research isn't always right!

DragonFly98 · 08/12/2023 13:38

First three dc were GGG

Older parents more likely to have girls I thought, although IVF likely boys (and Ivf more common for later pregnancies). But my ivf baby is a girl so eh!

DelphiniumBlue · 08/12/2023 13:40

Other people I know with 3 DC:
BBG
GGG
BGG
BGG
BBB
BBB
BBG
BGG
GGG

But I'm just wondering, how would families where the 3 DC have different fathers affect the outcome ? Isn't it the case that it is the father's sperm that decides the sex of the child?

DappledThings · 08/12/2023 13:40

These are all the sets of three I know.
BBG
GGG
GGB
BBB
GBG
In these 2nd and 3rd are only the same when all three are the same.

All pointless anecdata though.

TurkeyLurkeyChickenLicken · 08/12/2023 13:41

jesterdourt · 08/12/2023 13:43

I thought younger parents are more likely to have boys?

All the threes I know are same sex.
