For students hospitalized because of chronic or complex conditions, maintaining SoSB is challenging yet essential for successful school reintegration.\n\nMethods\nUsing a Grounded Theory approach, this study combined interviews with 16 parents, 32 mainstream teachers, 31 hospital teachers, and one association, alongside drawings from 14 hospitalized students. Data were collected pre‐ and post‐COVID‐19. Drawings were analyzed through a meaning‐making approach, and all materials underwent iterative coding and constant comparison.\n\nResults\nStudents reported strong emotional bonds with hospital teachers but felt forgotten by their mainstream schools. Peer contact was limited, and teachers felt unprepared to manage absences and reintegration. Structural gaps and weak communication between schools hindered continuity. Both formal (e.g., remote lessons) and informal (e.g., messages, drawings) exchanges, along with psychologists and associations, emerged as protective factors.\n\nImplications for School Health Policy, Practice, and Equity\nFindings highlight the need for integrated school–health policies, teacher training, and structured collaboration to ensure equitable relational continuity.\n\nConclusions\nPromoting SoSB during hospitalization is crucial for recovery, resilience, and educational equity.\n"]
