Pregnancy is the happiest period of every woman’s life. And, if the babies are twins, the joy is even greater.

According to a research, published in the Public Library of Science One, only the twin fetuses learn to socialize while they are still in the mother’s womb.

Babies Fight

The research has also shown that the behavior of the twins can be depicted even before they are born.

The following video shows cute twin babies moving in their space in the womb. However, the movement of these babies appears as if they are fighting and then apologizing to each other.

Twins argue all the time, but these two started to fight in a very early stage, which is in the womb itself. This video presents an adorable interaction between twin babies.

One of the babies is kicking the other, while the other replies by kissing him on the forehead.
