Two clinical cases where children beat their parents are used to elaborate hypotheses to grasp the issues underlying this phenomenon that are at stake for individuals, the couple and the family. Taking in the broader scope of social changes engendered as to representation of the parental function, attention is devoted to the childhood problematic arising where parents devise narcissistic pacts governing the couple and fail to differentiate their role as parents. This leads on to investigating what is at stake here at the intra-psychic level. Finally, we also examine the special period of pre-adolescence or adolescence when this problematic emerges in all its clarity.
