GFCF DIET ~ Heavy Therapy..one on one. My great-niece was diagnosed at 2.5 yrs. She has been on this diet pretty strictly since first of the year and therapy about 3X/wk. Now they are wondering if she ever was Autistic as she is talking (4 yrs.old) and just acting so much more normal. It was such a joy and miracle feeling when I took her shopping and she said she wanted the Sleeping "Buewy" Doll. Also special milk very strict diet.. no wheat, gluten...there are sites on the web of mom's that chat about this awful problem (sorry I can't remember name) but keep searching it is not easy by no means but it is soooo worth it. One time she ate a regular donut because her little sister had one and by that night my niece said she was going back to her old ways...THAT FAST!
