Poll: Did you have the same gender baby on second birth to first?

[kateyfer]

Hi MNer's,

I'm currently expecting DC2 and wanted to conduct a quick poll on likelihood of having same sex child for DC2 as DC1. Of all my friends/child's friends, everyone I know seems to have had the same sex child for first and second births!

anyone know if there are any stats on this?

what has been your experience? what did you have first and second time?

well, maybe, maybe not then! It would be so nice to know cause and effect!

Good luck gingerone I hope it goes well for you both. Was she concieved early or late in your cycle? I heard that girl sperm survive longer, and boy sperm swim faster, meaning that if you have an accident early in your cycle, it's more likely to be a girl, and if it's very close to ovulation, it's more likely to be a boy..... whaddaya think?

DD then DD here, 16 months apart.
I am a girl after three boys in my family, 15 mo between me and my closest brother

Falasportuguese - DS2 was conceived most likely on the day I ovulated sothat fits with your theory. We know this only because dh was working away and came home on the day of my smear test during which the nurse mentioned I was probably ovulating...

Age gap theory :
Dd1 to ds1 21mths
Ds1 to dd2 3.5 years
Dd2 to ds2 2.5 years
So a gender change regardless of gap between them.

We dtd 6 days before I got the indicator I was about to ovulate on the OPK.
Our adorable DS didn't read the whole gender theory

Weeeelllll! The "accident" that is my DS1 was on my Ovulation day( day 14) and the "accident" that will be dc#3( and seemed to have girly bits at scan) was day 8 of a 29 day cycle but still hasn't popped out to say Hello.

Middle child (the only officially planned one!) was day 12 and a boy.

I prefer to see my kids as planned but a bit early (18mth in ds1's case! and prior to getting around to talking my DH into it in dc3's case )

LOVE them whatever flavour they are!!

Would love a DD, but am sure I'd have another DS!

DS, DS, DS, don't know about this one yet. Someone said the older you are the more likely you are to have girls (but when I went to a young parents group it was fairly evenly split). Also unplanned babies are more likely to be girls but ds2, my uncle and dh were all unplanned.

I wanted a DD as a second child and bought a fertility thermometer (you put it in your mouth...) and made sure we atttempted conception when my temperature dropped by a fraction; well before day 14. It meant it took 6 months of trying, but it did work! For the record, my MIL gave me a newspaper cutting about it from when she had done the opposite to conceive her DS - my hubby, 30 years earlier. DD now teenager but despite this ... no regrets!

I have 4 DC. Just had a boy after 3 girls! :) I think each conception it almost is exactly 50/50, though apparently fractionally more boys born than girls.

DS then DS

7 DSs!

Well 6 DSs and 1 on the way

I've got 2 ds's.

I have a DS and am expecting a DD this time. Am a bit about the 'ooh perfect, one of each. You won't need to have anymore now' comments though.

2 DSs. Agree that it'll turn out to be more or less 50:50 with large enough sample.

What I want to know is, is there any medical or statistical truth in the widely-held belief that if you have two DC of the same sex, the third is overwhelmingly likely to conform to that sex too? If it's true, I presume it's something about the gametes particular to that mother:father couple - e.g. some parent combinations are never going to be able to have girls. (disclaimer: I have absolutely no idea what I'm talking about. Insight from someone with biological expertise would be welcomed!)

I did a bit of googling on this subject when expecting my 3rd child (DD3 as it turned out). Here.

DD, DD, DS. Did a lot of planning and charting to get him though!

Clever you tonks!

BTW that might sound sarcastic - it isn't supposed to!!

2 DSs

They seem to come in waves in my family. My generation (my siblings and cousins) were 8 girls and then many years later 1 boy. The next generation (ie including cousin's children) are now 8 boys and 1 girl - glad nature has redressed the balance!

3 DD's followed by 2 DS's.

My mum had dd, ds, ds, dd and all of my aunts had a ds followed by dd. I'm due in a fortnight with my second (sex unknown) and already have a ds, quite curious to know if I'll buck the family trend or not.

Just for the sake of being interesting, as I'm pg with DC1, I have done the Duggar woman's children.

If it's a girl, she will have 10 of each. How quaint.

I bolded the DS's to keep track.
