In my child psychology course in college (which I dropped out of because I was so disturbed and offended) the professor did speak about these difficult to raise infants and young children who acted in a rejecting, difficult-to-satisfy manner. She spoke about the research and reality that showed they were more likely to be abused.

It was a very very very difficult discussion.

At the time, I literally couldn't handle it- I was young and had just left my abusive parents, I was afraid and disturbed to consider the abuse might be my fault or any child's fault.

Of course, my professor was NOT saying abuse was the child's fault, she was explaining that certain behaviors and types were more likely to be abused, a correlation, not a justification.

So, yes, I've heard and talked about this some. Sigh.
