This article describes the infant-parent psychotherapy of a 6-month-old girl. This anxious, almost inconsolable, baby girl used withdrawal, dissociation, self-harm, auto-stimulation, and passive to active reversal, especially with her mother. Both her parent's feared she was autistic. Indeed, the baby, as if protesting what she felt to be a painful interaction with her mother, developed defenses that, to the author, looked autistic. During five months of infant-parent psychotherapy, her parents learned to contemplate her emotional life and helped her become a normally developing toddler. This case raises the question: If the child's defenses had become entrenched, would she have eventually been diagnosed with an autism spectrum disorder?
