I keep hearing that first babies are usually "late".  Does anyone have a link to an actual study?  Not that I think it matters, I'm just curious.

My bub came 3 days before his due date. I was my Mum's first and I was 2 weeks early (though I'm sure that isn't all that common).

Sorry, I don't have a link.

1st bub was due on the 12th and even though I went into hospital on the 10th, I had her on the 12th.

They say statistically you're more likely to go overdue with #1, but there is (in my opinion) more evidence to suggest that women will follow in the footsteps of their own mother.

From a family of 41-42wk PGs

I only made it to 37w5d with #1.

#2 was evicted at same gestation.

#3 was even earlier at 36w3d.

My little sister only made it to 35w5d she had HELLP Eclampsia and bubs had to be removed for both their sakes. She was in ICU for 4 nights herself.

My nephew was two weeks early.

Number 1: due 31/12, arrived 10/1
Number 2: due 31/10, arrived 12/11 (c/section as he showed no signs of wanting to get out - I was so over being pregnant )

No hard evidence, but Mum had me and both my siblings early. This little terror decided she wanted to try and make an entrance last Saturday at 34+3. She's still happily in there due to drugs to stop labour, but I think sometimes looking at your Mother's experiences can ring true.

My mum went over with me.
DD was 5 days over and DS was evicted at 11 days over.

Ok... found these ones for you:

Link http://spacefem.com/pregnant/charts/duedate0.php

This one has a graph showing studies of over due pregnancies.


Link http://www.inspiredchildbirth.net/overdue-pregnancy.html

"We also know the average length of gestation for a first pregnancy is not 40 weeks like all the due date calculators use, but 41 weeks and 1 day. (This is according to research from the 1990's. The 40-week measure came from data collected in the 1800's and continues to be used in spite of this new finding.)

So what is normal for length of pregnancy and gestation?
Well, we know average is 41 1/7 weeks. We also know that in nature, the normal curve describes the range of normally observed behavior. For pregnancy, the normal range is about 37-43 weeks.

Dr. Bradley likens it to the way apples ripen at different rates on a tree. He warns us not to pick an apple (or baby!) before it's ripe. In fact, many experts are concerned about the large number of mistimed labor inductions in recent years. As a result, more preterm infants are being born, causing increased complications and need for time in the NICU or special care nursery."

I found one set of stats here: http://answers.google.com/answers/th...id/233200.html taken from a Canadian paper: "Recent Trends in Fetal and Infant Outcomes Following Post-term Pregnancies"

Here are the general stats, too... rather interesting!

Breakdown of full term births by week:

37 weeks - 4.76%
38 weeks - 12.65%
39 weeks - 19.54%
40 weeks - 37.27%
41 weeks - 13.71%
42 weeks - 4.96%
43+ weeks - 0.41%

37 weeks - 5.69%
38 weeks - 14.36%
39 weeks - 21.56%
40 weeks - 32.44%
41 weeks - 14.65%
42 weeks - 3.40%
43+ weeks - 0.13%

Presumably the missing percentage applies to births before 37 weeks.

Thanks for the links - but is there any evidence that first pregnancies are statistically longer than subsequent ones?  Which seems to be the "everyone knows" fact.

#20 Lovingcountry

Posted 20 November 2012 - 07:25 PM

Hey there!

This is the only link I found that actually addresses the "everyone knows fact" that first time mums came late although I've found nothing conclusive yet.  Good question though!


My first was 15 days over due but these days they won't let you go that long!

#21 Roobear

DD - 40+11
DS - 39+6

OK... I've gotten close now...

"Robert Mittendord of the University of Chicago Medical Center has isolated 16 factors that can influence the accuracy of a predicted due date. Ethnicity may play a role; African-American women, for instance, often have pregnancies that are, on average, three to eight days shorter than those of other women. First-time mothers can almost be counted on to deliver ten days or more after their due date. The length of gestation seems to peak for babies of mothers who are around 29 years of age, so maternal age may be a factor. Caffeine consumption makes pregnancies shorter. Taking The Pill up to two months before conception can cause havoc with due dates. Finally, because biologic variation in fetal size increases throughout gestation, ultrasound dating can be deemed somewhat reliable only in the first trimester."


This page is worth reading.  Basically it says there are elements making it more likely for a women to go o/d but it's simply not an exact science

That's it for me!!  They basically all say the same thing LOL

Both mine were due daters. Who knows when this next one will arrive.
It's not really something u can put statistics to. Babies come when they're ready. It depends on the woman's cycle, their health and all sorts of factors. There's heaps of cases where women are induced/have ceasers just to fit in a ob or whoevers schedule. Obviously there are cases where intervention is necessary :-p but its done more than it needs to be.

I was mum's only baby and a month early.

My first baby was 2 weeks early, second baby was right on his due date.

DS arrived on his due date and my waters naturally broke that morning.
