Indigo/Crystal children

I have two young boys, aged 8 and 4 who i believe to be indigo children. I knew from a young age that my eldest son was different.. He talked of his passed life over and over as soon as he could talk. He described his job,his house and even knew how he died.. He was only two when he started talking to a man called Jim Jackson and Peter Jackson who apparently lived at my mothers house.. He had a number of imaginary friends too.. He is now a member of Mensa hes amazing.. He loves to learn about Crysal healing.. I f any one comes in to our hose with a headache,toothache etc.. He knows exactly which stone will cure them.. I discouraged his abilities at first as i was unsure of what to think.. He now speaks telepathically to my four year old son.. They play games reading each others minds they are both amazing and there is not a day goes by that i dont thank the universe for my amazing two gifts!! I just wondered if there are any others out there??
