This is a quote from the article:
Diane G. Sanford, a psychologist and author specializing in women's reproductive mental health, said while she doesn't know much about Nadya Suleman's background, women that have obsessive-compulsive disorder can become fixated on different obsessions.
Whether it's washing your hands 180 times a day or being obessed with popping out babies you have NO intention or plan on supporting, goes beyond the realm of normal behavior. I guarantee that she can be diagnosed with multiple issues, - probably lacks a sense of the reality surrounding her. Her extreme case is being confused with a woman wanting a large family, but having the right supportive elements in place. Living off your parents and driving your own mother to have psychiatric problems and not caring about how all these children will be fed and cared for, also seems a bit narcissistic (sp?)
