Whether they’re fraternal or identical, twins share things. Even if they don’t want to.
A new MRI shows twins “fighting” in the womb. Though it looks like they`re saying, “It’s my womb, no it’s my womb,” they’re likely just jockeying over space or position. This “womb with a view” provides fascinating insight on how twins interact with each other before birth. Even in the womb kicking is a form of communication.
This new view is called a Cinematic MRI and it’s being used to check for TTTS, Twin to Twin Transfusion Syndrome, a serious condition where one identical twin siphons the blood away from the other.
See, sometimes they even fight over blood. Call it sibling rivalry in the womb.
