A useless MN Poll - gestation of babies depending on season

[PavlovtheForgetfulCat]

So. In the interests of keeping me from boredom, and at the suggestion of tillyscoutsmum {ha, i shall blame you} I am asking this question.

My DD was a summer baby, born in 2006 when we had a heatwave. She was born 10 days early, relatively small (for no known reason).

This time, i am having a boy, and so far he is 8 days late, and not indicating if he intends to make an appearance soon. Thinking perhaps he is wanting to put a bit more fat on him to help him through the winter months!

Is there any correlation between winter/summer babies and how long they take to make an appearance?

Come and share and completely blow my very useless theory out of the water while I sit eating Doritos, soured cream and guacamole.

dd1 born four days late end of aug 05
dd2 born four days late middle of jan09

Well considering normal gestation is from 37 weeks until 42 you can't really say a baby is early or late unless they fall on either side of these dates. All the babies born within these dates have been right on time so that just throws your theory out of the water a bit doesn't it?

there is research into this - it did show that winter babies were later.

Well it works for horses!

My DS was born in August, 10 days late

effect of season on birth weight a human one this time!

DD - Spring 2004 on her due date
DS - spring 2009 ( same month) a week late

DD born summer of 2006, 10 days early.
DS born Winter/Spring 09, 7 days late.

I shall just pay attention to the ones that correspond with my theory, ok? .

I like those links too

Not sure if this works, but my midwife told me boys are more likely to be late and girls on time. My son was 11 days late (end of April, very warm weather) and all the midwives in hospital (when I was being induced) kept saying "ooh it's definitely a boy as he's being so stubborn".

Am hoping this baby is a girl and born on her due date.

DD 2007 3 weeks early (September)

DS born 3/9/09, by my dates 10 days early, by the look of him when he was born MW said 2 weeks late!!

Mine:

DS, January, 2 days early
DD, March, 2 days early

Me and my siblings:

Me, July, 2 weeks late
Brother 1, December, 3 weeks late
Brother 2, August, 2 weeks late
Sister, December, bang on time

DH and his siblings:
DH, February, a week early
Sister 1, July, a week late
Sister 2, May, on time

So our experience doesn't match your theory, I'm afraid.

DS1 April 3 days early
DS2 October bang on time
DS3 October 12 days late
but maybe this is going to be a harsher winter than 5 years ago.

DD, November, 14 days late

Works for me!
Good luck!

Works beautifully for my family...

DD - July, 8 days early. v.cold July though...

DS - October this year. 5 days late.
me & 3 siblings all autumn babies and all late.

DH and Sil, bornMay and April respectively and at least 1 week early.

Will add mine (been as they back up the theory )

DD - 1 day early - May baby

Me - 2 weeks late - December
DH - 3 weeks early - May

Our local SCBU is closed due to it being full. I'd say about half of the wee patients are there as they're prem. (Really prem. For some reason there seem to be a lot at the mo.)

Ds1 2 weeks early- December 27th.

Dd 2 weeks early- May 14th

Ds2 on due date- September 21st.

But- With Ds1 I had no idea of date of conception so pregnancy was dated from the 1st scan,but I was already 20 weeks pregnant! So he could have been on time, I don't think he was late, showed no signs iykwim!

Sorry- blows the theory

DD- 4 weeks early - born in July
DS- 6 weeks early - due in Feb but born early Jan
No apparent reason for either of them being early and both on the small side.

Sep - 3 weeks early
Jan - 3 weeks early

my older bro - due date - June
me - 2 weeks late - May

june baby, 3 weeks early.

I (my mum's PFB) was two weeks early in the heatwave of 1976.

DD was two weeks late in September last year, but I can't tell you what the weather was like, as I was too busy stomping around in a colossal mood and frantically scouring the internet for tips on inducing labour.

DD (July 2006) -- 7 days late
DS (Feb 2008) 2 weeks early
