" Young children cannot possibly understand the motives of adults. It means little to a young child that the parent feels love for him if that parent keeps disappearing at almost any time. The child experiences a sense of abandonment, a subliminal knowledge that there are things in the world much more important to the parent than he, the child, that he is not worthy of the parent’s attention. He begins to feel, at first unconsciously, that there must be something wrong with him. He also begins to work too hard to get his needs met: demanding contact, acting out or trying to please the parent to gain approval and attention. "
