This research which is focused on how children assume the process of grieving has two goals. First, it aims to understand emotional reactivity when it comes down to those defense mechanisms related to the loss of a close relative. Then, it focuses on understanding how girls build the idea of death when they lose a family member. Regarding methodology, this is a qualitative study with a hermeneutical approach and psychoanalysis, which has been used as a theoretical reference. This work involved the study of two young girls between 4-6 years old who lost one of their parents. Other family members were also interviewed, and various assessment techniques such as: interviews, projective tests and one-on-one meetings were used as well. Therefore, the results indicate that grief in the infant stage is a process that generates displeasure, linked to the forced abandonment of the investiture placed in the beloved object, and the helplessness projected in a psyche in constitution can be almost intolerable. Within the emotional manifestations associated with the loss, there are nightmares with a repetitive dream pattern, memories and daydreams with the deceased person; and the presence of regressive mechanisms after the relative’s death. Death is taken as a transitory event; therefore, death can be played without the definitive absence of the object of love being understood. The meaning of death derives, also, from family traditions and relationships with the other. The girls’ exposure to burial rituals seeks to eliminate from the subjectivity the plot of death as a transitory game, marking the idea of the material absence of the loved one. However, assimilating absence as a definitive and non-transitory act is a complex psychic process that goes beyond these rituals.
