What are Dutch twins?
The Dutch Twins are Kit and Kat, 5 years old and not yet big enough to be called by their real names, Christopher and Katrina. … The book is the first of a series of stories about twins in different countries, meant to give children an idea of life and customs in various parts of the world.
Can twins have different dads?

Do mothers of twins live longer?
Summary: Compared with other mothers, women who deliver twins live longer, have more children than expected, bear babies at shorter intervals over a longer time, and are older at their last birth, according to a new study.
Which is Twin A and Twin B?
By convention, twins are labeled as twin A or twin B at the time of birth, depending on their birth order. However, antenatally twins are labeled as A or B according to their location relative to the birth canal. Antenatal labeling is usually established by prenatal ultrasound.
When Should Twins be delivered?

Can you get pregnant while already pregnant?
In extremely rare cases, a woman can get pregnant while already pregnant. Normally, a pregnant woman’s ovaries temporarily stop releasing eggs. But in a rare phenomenon called superfetation, another egg is released, gets fertilized with sperm, and attaches to the wall of the uterus, resulting in two babies.
Why twins are so special?
Twins are always the same age, and they usually share a similar environment, both in the womb and while growing up. … Identical twins share 100% of their genes, while fraternal twins share only about half their genes (just like regular siblings).
Do twins live shorter lives?
Twins not only have a bestie from birth — they also live longer than singletons. … While twins have been subjects in countless studies that try to separate the effects of nature from nurture, a recent study in PLOS ONE is the first to actually look at what being a twin means for life expectancy.
Can siblings be 9 months apart?
Well, long story short, Irish twins are siblings that are born 12 or less months apart. Yes, it’s possible.
What is a good weight for twins at birth?
