This study investigated mothers’ narratives about their chronically ill babies' hospitalization at a public maternity hospital in São Paulo, during 2022, based on thematic analysis of four semi-structured interviews. The main qualitative data from interviews were analyzed concerning its psychoanalytic contribution, organized by three central themes. Interviewed mothers seemed to have found possible ways to perform the maternal function and bond with their babies. Their experiences were affected by ambivalent feelings and psychic suffering that demands mental health care. The aim was to come closer to this reality, remarking original motherhood experiences and the importance of developing caregiving practices worried about the needs of parental figures and their babies in the context of hospitalization and illness.
