15 Facts About Twins
15 Facts About Twins
My twins are 30 months old. (2.5 years!) WAIT…I screwed up. That is tomorrow. OMG I need sleep lol. But in case I don’t post tomorrow…..
Happy birthday little ladies!
1. The overall U.S. twin birth rate increased 76% from 18.9 in 1980 to 33.2 per 1,000 births in 2009. (The most recent data available.)
2. 22% of all twins are left-handed, while only 10% of the singleton population are left-handed.
3. Identical twins share 100% DNA and are conceived from a single fertilized egg that has split. Fraternal twins share 50% DNA, and are from two separate, fertilized eggs.
4. Identical twins share all of their DNA, however, they do not share fingerprints
5. Over 50% of twins are born prematurely.. (before 37 weeks).
6. Identical twins do not make you more prone to having a second set of twins as it’s simply an uncommon occurrence of nature, while bearing fraternal twins makes you 3-4 times more likely to conceive a second set.. (if conceived naturally).
7. Women over the age of 30 are more likely to conceive twins and that number continues to rise with advanced maternal age. For ages 35-39 twin conceptions went up 100% from 1980. There’s an over 200% rise in the 40 and up age group!
8. 1 in 250 pregnancies result in an identical twin birth.
9. Due to the increase in fertility treatments twin birth rates have risen to as high as 1 in 30 . By looking around I would certainly say that is true.
10. Fraternal twins (females) are at least twice as likely to have a set of fraternal twins of their own someday.
11. 40% of all twins invent their own special language between one another. I wonder if this 40% number covers identical twins as my fraternal set does not seem to have this language.
12. Heavier women are more likely to get pregnant with multiples.
13. The average birth-weight for twins is 5.5 lbs.
14. Only fraternal twinning runs in families. Though some would like to disagree, having identical twins on the family tree does not mean you are more likely to bear twins yourself. There’s also no evidence to support the claim that twinning skips a generation. That’s a myth.
(Hyper-ovulation can run in families, hence causing twin conceptions.)
15. The average time between the delivery of the 1st and 2nd twin is 17 minutes. (If born vaginally, of course.)
Just so you know .
And we’re still on the rise!
Happy holiday weekend everybody!
