Don't know if this will help but its something to look into. I have been hearing in my quest for knowledge that getting the gut bacteria built up can help with autism. Maybe you already know that but that's what I been hearing from experts that do the research. And I am always skeptical of any shot because I don't know whats in it and have to solely rely on trusting the doctor and he is most likely just trusting someone that told him or her. Hope that helps, good luck.
