My child’s stool test had very low bifidobacterium and lactobacillus species, so we considered implementing a probiotic to increase those species. What are your thoughts?

As I discuss in the book, stool testing from a sample from the rectum does not represent the bacterial overgrowth issues present within the small intestine. Furthermore, we can only grow a minority of the bacteria that live within the intestinal tract, so how meaningful can a stool analysis from the distal colon be? I vigorously oppose the use of any probiotics in the treatment of any child with autism or any developmental disorder.
