Growing up with a brother or sister is a special experience for everyone. When you’re young, you have a ready playmate just steps away. As an adult, siblings also have incredible bonds, always there to lend a hand or talk when you need them the most.
The bond between twins is particularly strong. Twins grow together in their mother’s womb and spend their childhood celebrating birthdays, first days of school, and other major milestones together. Some twins are so close that they even come up with their own secret language and communication system, as discerned from a new viral video.
In the cute video, two twin baby girls lie next to one another on a bed. The twin on the right then begins their conversation, gurgling and grabbing her sister’s hand. After a while, the little girl on the left joins in with her own coos and wraps her fingers around her sister’s hand.
While we, as adults, cannot understand the twins’ baby talk, those who have seen the video have their own theories as to what the two cuties are talking about. One commentator jokes that they are gossiping about the 4-month-old twin boys down the street, while another guesses that they are expressing their displeasure at their new formula.
Joking aside, studies have proven the undeniable bond between twin siblings. As reported in Very Well Family, twins can often feel a psychic sensation that “something is wrong” when their other sibling is experiencing a traumatic situation or physical pain like a heart attack. When separated, twins have also been shown to share similar preferences, such as liking the same types of food.
An article from the U.S. National Library of Medicine also presents evidence of personal languages developed between twins. The study found that 40 percent of twins develop what they call autonomous language, idioglossia, or cryptophasia. Most of these autonomous languages between twin siblings fade overtime, but one can surmise that the two little girls in the video are developing their own method of personal communication.
