When Sonia Rochel posted this video of two twins two years ago, she was simply trying to demonstrate her "baby spa" method of bathing newborns in warm water. She inadvertently captured something pretty special: these babies holding each other, as though still nestled in the womb.
The video illustrates the bond between twins that begins before birth.
A 2010 article by Scientific American states that at least one study shows that twins begin forming social bonds before birth: the first person a twin meets is his or her twin.
But what's surprising is how early that bond begins...
According to the article, one study "found that fetuses begin reaching toward their neighbors by the 14th week of gestation."
But there's more...
As the twins mature, they spend more time interacting.
The article continues, saying, "Over the following weeks they reduced the number of movements toward themselves and instead reached more frequently toward their counterparts."
"By the 18th week," Scientific American writes, "they spent more time contacting their partners than themselves or the walls of the uterus. Almost 30 percent of their movements were directed toward their prenatal companions."
Pretty amazing, right? Check out the video on the next page.
Here's the full video:
Although there's been a huge spike in twin births, they're still relatively rare.
Twin births remain a relatively rare occurrence, despite having risen 76 percent in the United States from 1980 to 2009, according to the CDC.
Are you a twin? If so, do you feel a special bond with your sibling? Let us know!
