The technology of ultrasound proved to be a helping hand for the researchers as it made them able to change the depth of visual field, frame rate and the sweep angle.
On examining the recordings, it was found that the fetuses made distinct gestures when they touched each other, and movements lasted longer, their hands also lingered. They even took as much care when touching their twin’s delicate eye region as they did with their own.
This study makes it apparent that the twins start deliberately touching each other in the womb. As they are buried too deep inside the womb, so a mother can’t feel their movements. However, after a few more weeks, the twins start kicking.
More facts about twins:
Approximately 90,000 sets of twins are born in the United States every year. Women who delay having children until after the age of 30 are slightly more likely to have twins.
The perinatal mortality rate for twins is significantly higher than that for single babies. During this period that encompasses the time shortly before and after birth, twins are five times more likely to die than individual babies.
The chances of giving birth to twins is roughly 1 in 90.
