[Neonatal death of a newborn twin]

In France, in 2001, 33,000 children were born from multiple pregnancies (4.2% of births). Lately, with the stimulated fertilization improvement, this number has strongly increased. These pregnancies are pretty often difficult and the hospitalizations of the twins (or other multiples) in a neonatal intensive care unit are more frequent than in a single pregnancy (48 vs. 5.3%). Newborn twin death leads the parents to face a tough mourning because of the surviving twin presence. The psychiatrist's function is crucial with the parents, the deceased child, the surviving child and the pediatric staff. Therefore, as much as possible, the psychiatrist (or the psychologist) has to gather and work through the confused feelings of the parents. Several splittings occur in this situation. Some of these splittings concern the medical staff, some others affect the children, the dead one and the living one, either rejected and disinvested or idealized and overprotected. The child psychiatrist is a preferred recipient for the different projections of the parents.The hospital staff as a whole has to understand their full significance and their important psychic sparing for the couple. As the deceased child, the psychiatrist may look bad and unsatisfying, for instance: "he doesn't answer as we would like", "he doesn't come up to the couple's expectations", "he doesn't talk enough", "he's leaving too soon", etc.In addition, the psychiatrist may be attacked as the representative of the pediatric staff, in order to preserve in a better way the others medical protagonists, still essential for the survival of the alive child. These parents are in mourning and the psychiatrist must help them in this process in order to improve the specific investment of the surviving child, the attachment and the communication with him.
