Clearly, these two adorable twins have a bond that can't be broken. The twin unit is a powerful and unique relationship that can last a lifetime and science can back it up.
Because twins are given an intimate amount of space during fetal development, a physical and emotional bond is formed almost immediately. There is a sense of familiarity between the pair, which can lead to an increase in early social skills. Children who are a part of a twin unit are more likely to be extroverted and tend to enjoy working in groups.
These two look like they already have an amazing and socially bountiful relationship. Hopefully, this beautiful bond will remain throughout their lives.
