Sounds mad but it’s true, honest! If you have 3 kids…

Same dad, no miscarriages to ‘break the chain’, if the first 2 are opposite sex, the third will be whatever number 2 was - so BGG, or GBB. Not BGB, or GBG.

It sounds crazy but it’s something I noticed ages ago - every time somebody announces they’re having a third, and they have one of each, I know it will be the same as the second child.

Prove me wrong, Mumsnetters!

Not true for my parents, my DH’s parents, my grandparents, any of my friends or cousins, or many of the families at school? 🤷🏼‍♀️

funinthesun19 · 07/05/2025 20:42

BBB for me. Then G

Kaleidoscope2 · 07/05/2025 20:42

Sorry also not true, my friend has three GBG and all with her husband

samarrange · 07/05/2025 20:41

Sex is determined by the sperm. Your DH's sperm have no idea what the last two "successful" sperm did.

I'm starting to understand why horoscopes are so popular.

PeloMom · 07/05/2025 20:41

Nope. I know of many BGB combinations.

Strawberryorangejuice · 07/05/2025 20:40

Erm yep, that works here! I'm trying to think of who else I know to prove the theory!

Montsti · 07/05/2025 20:39

Mine are BGGG

TroysMammy · 07/05/2025 20:39

I know a lot of two of the same and the third or fourth are the same too so BBB or GGGG. Some of my cousins BGGG, GGG, BGG, BGGB, BBB, GGG, and only one set GBtwinG.

Tavimama · 07/05/2025 20:39

Nope. I was the oldest, then my sister, then our brother, so: GGB

lljkk · 07/05/2025 20:38

Hard for me to comment because my mom had miscarriages (she lost count, she wasn't bothered by them) and otherwise I don't know who had miscarriages when. My guess is that most of us don't know about anyone else's miscarriages, so most of us have no clue.

I never had a misc & had BGBB, so doesn't fit OP's theory.

GRCP · 07/05/2025 20:38

My mum had GBB(GGG)
DB had BBG so I guess doesn’t count
Friend had GBB(B)
Trying to think of other people who had 3 DC with same partner…

Vogue Williams had BGB but wouldn’t know if she had losses

CalleOcho · 07/05/2025 20:37

no miscarriages to ‘break the chain’

Wow what an awful way to refer to miscarriages.

BlueMum16 · 07/05/2025 20:35

Someone I know has BB and then twin girls.

Horses7 · 07/05/2025 20:33

Utter tosh! 🙈

CharlotteCChapel · 07/05/2025 20:33

I have BBG, DD has BBB, one gran had BBB and the other GGG.

makemineadecaf · 07/05/2025 20:32

GGB

You’ll all notice it now I’ve said it!

It's not true though. Just did a quick mental tally of people I know and including my own I know 7 families with 3 kids where the middle child is a different sex than the oldest and youngest; and 4 where the two oldest are the same sex and the youngest is the opposite sex. In my circle of friends and family there is only one BGG family..

Allmarbleslost · 07/05/2025 20:30

I have two family members who have 3 kids; GGB and GBG

Member984815 · 07/05/2025 20:30

I'm one of 5 bgbgb same dad no miscarriages

Quercus3 · 07/05/2025 20:29

I have GBG, know 2 others with the same

mummysmagicmedicine · 07/05/2025 20:29

My mum had BGBG

FcukTheDay · 07/05/2025 20:29

I have GBGG

Newusernameforthiss · 07/05/2025 20:28

No.

The ones I know
GBG
GBG
GBG
BGG

I would say the exact opposite to you 🙃

ItGhoul · 07/05/2025 20:23

Nunaluna · 07/05/2025 20:03

Just to clarify I don’t mean it’s true in every single instance - but more than it should be statistically if that makes sense? So 80%+ of the time (my very scientific anecdata!)

Show quote history

Nope, still bullshit.

FWIW I’m the third child in my family and we’re GBG. My brother’s kids are BGBG.

Emelene · 07/05/2025 20:23

I’m having GBG, currently pregnant with my 3rd. Surely it’s 50/50 for each sex?
