While having a twin might sound fun, a new study suggests that it could come with some worrying side effects. The study, by researchers from Northwestern Academy of Sciences , has revealed that women with a twin brother are less likely to marry, have children, or go to university.
It's equally unsurprising that a Danish study found that twins are less likely to get married than non-twins. As twins have a partner from birth, the study suggests that they may not have the same desire for marriage as singletons.
Moreover, moms with twins at first birth had divorce rates of 13.7% compared to 12.7% for single first births. From the figures above, it's clear to see that twin births may be linked to higher parental divorces.
Key points. Competition, jealousy, sharing, and expectations make twinship a hard relationship to navigate. Twins are sometimes confused as to who they are in relationship to each other. It's important not to make twins feel guilty or ashamed if they don't get along.
Though twins are not that different from non-twin siblings in a social environment, twins deal with a different set of anxieties when it comes to expectations in relationships. Unlike other siblings, twins often have a codependent relationship and may begin to expect their twin to always want the same thing.
The Science of Fraternal Twins. Mixed-gender twins are the most common type of fraternals, some 50 percent are boy-girl. To understand this combination: Males have XY chromosomes, females have XX chromosomes. You have a girl twin when the father's X chromosome combines with the mother's X chromosome.
The longest interval between the birth of twins is 90 days, in the case of Molly and Benjamin West, dizygotic (fraternal) twins born in Baltimore, Maryland, USA to parents Lesa and David West (all USA) on 1 January and 30 March 1996.
Twins suffer more intensely than single-born individuals when they feel “alone.” Although it is hard to put into words, the intensity of twin loneliness makes understanding and managing such loneliness difficult and sometimes overwhelming for twins.
Twins and other multiple-birth individuals can suffer from much deeper and troubling loneliness than single-born individuals. Separation anxiety, which often begins at birth, is the underlying cause of loneliness for twins.
Researchers from all over the world have found that when one identical twin is depressed, the other twin will also have depression 76% of the time. With fraternal pairs, the twin of a depressed person experiences depression only 19% of the time.
"Twins tend to be closer than typical siblings — they share a bond that is oftentimes unexplainable," Maureen Healy, an expert on sensitive children and author of Growing Happy Kids, tells Romper. "Many believe this is rooted in genetics, such as identical twins sharing the same DNA."
Families with twins experienced a significantly higher incidence of child abuse and neglect than did those with single births (p less than . 003).
Twin psychology has been studied to a very limited extent. Only few remarkable peculiarities of the twins'" development are known for sure, such as delayed intellectual development, language retardation with frequent cryptophasia, difficulties and fragility of self consciousness, reduced sociability.
According to the Office on Women's Health , women who are aged 30 years or older are more likely to conceive twins. The reason for this is that women of this age are more likely than younger women to release more than one egg during their reproductive cycle.
However, for a given pregnancy, only the mother's genetics matter. Fraternal twins happen when two eggs are simultaneously fertilized instead of just one. A father's genes can't make a woman release two eggs.
What are the benefits for the twins? Their buddy is always there. They've known each other since they can remember and that is very comforting. They are also a little more social than the average child since they are used to being with another kid since the beginning.
Race. African-American people assigned female at birth are more likely to have twins than any other race. Asian Americans and Native Americans have the lowest rates for twins. White people assigned female at birth have the highest rate of higher-order multiple births (triplets or more).
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). The concept of concordance is important in twin studies.
Some say that twins are always hard (yet amazing), while others say they truly didn't find them to be difficult. A few said that the first two months with twins are easy (being in the rose-colored glasses phase), then reality hits from months 3-6 (when the sleep deprivation catches up), then it can get easier again.
The findings show that twins have a survival advantage over the general population at nearly every age, and between the two types of twins, identical twins have a survival advantage over fraternal twins, said David Sharrow, the lead author of the study and a demographer and postdoctoral researcher at the University of ...
It may be unspoken, but sometimes, parents of multiples do have a favorite child. Of course, this doesn't mean that they don't love each of their children, but rather that they may feel more bonded to one over another.
So the firstborn is really the youngest. Answering the “which twin is older” question from strangers is one thing. Fielding the questions from friends, family, or the twins themselves is another story. You should discuss as a couple your approach for answering this question with people you know.
For the most part, twins and multiples share the same birthday. However, depending on the time of day the babies are born and how long the timespan is between each baby's birth, twins can be born on different days.
The interval between vaginal delivery of the first and second twins (mean, 21 minutes, range, one to 134 minutes) was 15 minutes or less in 70 (61%) cases and more than 15 minutes in 45 (39%) cases.
