This is absolutely crazy if it did happen. Okay I have a clinical background - the first thing I would do is look up the "lay in bed with little girl" intervention. The other thing I question now, is, after all of this trauma, how are these people not living on skid row with a needle in their arm? They seem relatively normal and put together - life doesn't usually work like that.
Also, the parents didn't press charges for fear of their personal relationship with B. However, they are okay with the whole world knowing now? Why?
