A girl I once knew told me that she be able to accomplish an autistic child by simply "coming into their world".
If he was sitting and rocking, she would sit and rock next to him...she'd mimick his every move...and eventually developed a trust with him, and consequently he overcame it.
Nutritional support is just one of the lots therapies that can give support to an autistic child. I think that you will requirement a multitude of therapies for better results. Many say that it is unachievable to recover from autism but incontestably brain functions can improve next to vitamins and other methods.
