"Difficult." "Picky." "Oversensitive." "Clumsy." "Unpredictable." "Inattentive."

This guide, written by an expert in the field, explains how SI Dysfunction can be confused with ADD, learning disabilities, and other problems, tells how parents can recognize the problem-and offers a drug-free treatment approach for children who need help.
