Recently indigo children started uniting into groups as nobody understands them as they can’t find friends among other children. Maybe your children are also indigo children or maybe you are indigo child. Somehow or other, indigo children are more developed spiritually.
There was no official term to name the phenomenon of such children for a long time. However there were attempts to give the certain name to it and very attempt had serious scientific bases. They were called "children of the new millennium" because these young creatures have unusual psychological possibilities.
They were also named "children of the Light" because their views on the world are different from the views on the world of ordinary people.
They are also often called "gifted". Any test fixes the level of development of these unusual children. (The school marks are not able to fix their knowledge). There are a lot of unusual children in France that were called "Teflon" as usual models of behaviour don't "stick" to them. But the most common term to call them is "indigo-children".
The first one to investigate these people was Nancy Ann Tapp. According to her, people of every stage of the development of humanity had auras of different colours. And in 80-s she saw the baby with dark blue aura and from that time she decided to add one more colour to the spectrum of the world. And indigo-children became the discovery of the 20th century. And this has become the first stage of the development of investigations.
