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!

maybe you’ve seen a pattern would love to see some actual stats! Many of the posters aren’t listening that you said children of the opposite sex first.

i have three girls and a few miscarriages in between so wonder if they were to be ‘boys’

It's an interesting observation! It took me quite some time to even think of families who have 3 kids and the same dad! Families seem to be much smaller these days.

WorkItUpYourBangle · 08/05/2025 18:55

Nope. GGB for me

redhotpokamum · 08/05/2025 18:53

I’m one of 3 and GGB

FreddieMercurysCat · 08/05/2025 18:52

BBB here, although middle B is now a G.

katseyes7 · 08/05/2025 18:48

No. My best friend is the middle of three and she has an older and a younger brother.

Bryonyberries · 08/05/2025 18:48

I had BGGG.

sueelleker · 08/05/2025 18:48

Does this only apply if you stop at three? My sister has five kids; three girls, then a boy, and another girl to finish.

Missingpop · 08/05/2025 18:47

You need to get out more; I imagine you sit rocking waiting for the postman & lick the windows with excitement when the milkman’s due for his money 🤦‍♀️ the excitement is just to much

Partridgewell · 08/05/2025 18:47

Works for me OP - GBB.

It’s just something I’ve noticed - every time somebody with a boy and a girl announces they’re expecting number 3 I think ‘oh yeah that’ll be a boy/girl’ depending on what number 2 was, and sure enough I always seem to be right!

Have you come across the term confirmation bias?!

canyouseemyhousefromhere · 08/05/2025 18:45

Well I’m no.3 with older sister then brother same parents.
GBG

Kevintheelf80 · 08/05/2025 18:44

My mum had gbgb and I have gbg as do 3 of my friends

QuartzIlikeit · 08/05/2025 18:43

BGB here. No miscarriages either

Crunchymum · 08/05/2025 18:43

I'm BGG but I've had many miscarriages over the years.

Only other people I know know with 3 are GBG and BBB.

My anecdotal theory on siblings when you just have two is there is usually only 1 or 2 months between them if end of one month and beginning of another. So sibling group one July and August, sibling group two July and August, sibling group three October and November etc etc every 2 child family I know follows this pattern regardless of year age gap.

Mine were November January.

slapmyarseandcallmemary · 08/05/2025 18:38

Bgg

auderesperare · 08/05/2025 18:38

Like many on this thread, I had GBG, same father no miscarriages — I don’t believe there is any scientific evidence for this.

TheignT · 08/05/2025 18:38

The late Queen had boy girl boy boy. If it's good enough for her it must be ok.

Beautifulweeds · 08/05/2025 18:37

Sorry not true for my family. Xxx

Anothersayinparadise · 08/05/2025 18:36
