Social interaction happens before a baby is born, that is if there is another baby in there as well!
Twins begin bonding and interacting in the womb when the fetuses are only 14 weeks old, according to research.
As fertility treatments improve, the number of multiple births escalates, and twins are on the increase.
This goes for triplets, and quadruplets too.
Other factors are associated with the rise in multiple births, such as genes, obesity, being tall, older mothers, a diet rich in yam, or perhaps pure luck.
Dr. Rodrigo da Rosa Filho is a fertility expert in Brazil. He has written several books on obstetrics, and is very experienced when it comes to multiple births.
In a video of newborn twins he uploaded to Instagram, we see the precious bond shared between the two.
Just after birth, the pair are seen with their arms wrapped around each other. They appear to be consoling each other.
It’s a huge moment for a newborn on the cusp of life in the world. Having your other half there with you is something precious, and we never tire of watching these heartwarming videos.
