I find this an interesting topic, sparked off by Alisa noting some childrens eyes are almond shaped.
What are Indigos?
Indigos are certain people who have been born on the Earth over the past hundred years.After World war 2 a lot of Indigos were born and these are the older adults of today. Apparently another large wave were born, in the 1970's.
The term indigo comes from them having a lot of Indigo in their auric field(electromagnetic field that surrounds the human physical body.Many of them are clairvoyant.Some of the children have been labelled with ADD( attention defecit disorder)and are medicated, sedated, to enable them to conform to what society expects normal behaviour to be. The eyes tend to be large and bright.

What are Crystal Children?
The term refers to the children who have been born from around 2000.
The eyes are bright and large and appears when looking at you they pierce deep inside your soul. They are highly sensitive, psychic and telepathic. They have a kind of pastel iridescence in their aura. Some of them are labelled Autistic and have problems with speech and don't start talking till around 4 years old.

Does any of the above information resonate with you?
