Our four year old "is autistic" with pretty bad eczama. He's a pureblood but has a lot of trouble communicating. One mild dose of CDS and he starting forming not perfect but full sentences. That continued to improve over the course of a full course. We then switched him to a full parasite protocol - the old fashion one. Marked verbal improvement the next day and continuing. My neighbor commented he could tell something was different with him from 300 yards away. Never give up!
