Can you prove my theory wrong!!!!

[deleted account] ( 154 moms have responded )

I have a theory that so far within my circle of friends remains true.



"If you have children within 18 months of each other they are both the same sex."



My first was a boy and born in September 2006 we concieved our second child when Jace was 9 months old. There is only just 17 months between them and they are the same sex.

Girl 17.5 mths old when I had our boy in 2010.
I theorise that if both parents come from a similar pattern of gender, they will probably follow that pattern.
Eg.,
My mother had girl girl boy girl girl
Hubby's mum had boy boy ... the two patterns were a factor for us: Girl girl boy.

Hubby's brother's children follow a pattern like his wife's sibling pattern: Girl girl girl boy girl, as does her oldest sister. Fiona's 3 other siblings all take after their spouses' sibling patterns.

They say, if you give birth so close you get the same sex, there is no such as I have a baby girl of 30 month and a baby boy of 13 month so the gap between them is 17 months.

I can't disprove it, but I think it scientifically depends on the dad! Mine are 17, 9 and 4 and they are all girls!

Wrong!! :) I know someone with that gap and has one of each! I have 2 years to the day between mine, and 2 daughters. Gender determination is down to the sperm that fertilizes the egg, which is more or les a 50 50 schance...there's a slightly higher chance of having a boy I think about 51%...

my daughters are 10 months apart so the theory holds true but my second daughter and my third child are 16 months apart and my third child is a boy. My Third and fourth child are 15 months apart and my fourth child is a girl. So im going to say its the luck of the draw.

i have 2 beautiful children about 16 months apart a boy named troy jr 22 months now and a girl Kyra Jade 5 months and 2weeks old so i found that lucky as i wanted one of each sex and now i have it but my sister-in-law has 6 children (all boys) no more than 18 mths apart and now just giving birth to another boy (1 months ago) she is pregnant again (8wks with a girl) so im not sure..

No, I know alot of people who have kids 17/18 months apart and they are different sexes. Tho I don't know them all personally. But I do have a very close friend who had her first two 17 months apart and she had a boy and a girl :-)

Hmmm - there was 16 months difference between our eldest (girl) and second (boy), 12 months difference between him and our third (girl) and 14 months difference between her and our fourth (girl). Not sure if that helps your theory though, sorry!
