Have you thought perhaps about music?
If certain types of music stimulate a developping babies brain in the womb, perhaps the mental stimulus can help with this?

It will certainly get connections forming from the geometrics of the music, so I'm talking more classical music, if he enjoys it?

Elestials help you remember perfection....and I am still in confusion over this, certain things have changed for me while working with crystals, others havent and others have changed quickly, so I do know they work, but for me to say helping him remember his perfection sounds upsetting to me....one of the sets of words from Melody's books, all voids must be filled, and voids are filled with Love,...

also, I would ask his doctors whether meditation music might be good for him? there is a series of brain wave cds that move through the levels of waves, alpha, alpha theta, to gamma and the other two escape my mind for the second....delta and oh, theta by itself ;)

but I would definitely ask the doctor about those before you try that, although they will get the brain connecting to different parts of consciousness, but please, ask the doctor first, one of the things about these sorts of sound tapes is you are not supposed to listen to them if you are schizophrenic, which to me means, be careful if you are not completely centred before listening to them, or consider their use wisely...

I think the classical music is a pretty safe and healthy way of stimulating the mind though....
