There are several articles under the Autism & Autism Spectrum Community. Here is a sample with useful information regarding the 6 year old girl's diet: http://www.wellsphere.com/autism-autism-spectrum-article/diet-and-autism-fresh-evidence/1113473, http://www.wellsphere.com/autism-autism-spectrum-article/application-of-a-ketogenic-diet-in-children-with-autistic-behavior-pilot-study/739471 (discussing the possible success of a ketogenic diet), and http://www.wellsphere.com/autism-autism-spectrum-article/gfcf-diet-treatment-for-autism-unsupported-by-evidence/335472 (with evidence of the gluten-free, casein-free diet succeeding). I suggest you explore more of the community for the advice that other members can offer you.
