Hello Simon,
Welcome to the group...I am fairly new as well and love it here!!
My husband is Indigo and has many books on Indigo and Crystal children...we have found Doreen Virtue has many books out on the subject and are a very easy read.
We are also members of a on-line news letter that focuses on this subject alot!!
I can't remember the name of it at this moment but will look it up for you and send you a link....it is very informative!!
I have so many thoughts swirling in my head right now of things I could/should tell you about what I do know...but it is all jumbled right now and I do not want to overwhelm you with rambling...lol
So I am just going to suggest finding a book called "The Care and Feeding Of Indigo Children" by Doreen Virtue.
My husband loved the book...said it shed light on alot of things for him and also deals with Crystal children in it.
Hopefully that can answer some of your questions for you.
Welcome again
Love and Light
Stacey
