Sleep plays a crucial role in the development of newborns, especially for premature and low-birth-weight infants. Clustered nursing care is an effective way to improve these infants’ sleep quality and overall well-being. This approach has numerous benefits, including diminished stress responses, heightened physiological stability and improved growth outcomes. Moreover, it underscores the imperative of adeptly addressing sleep disturbances and mitigating stressors during neonatal intensive care unit (NICU) stays to optimise developmental trajectories. Ultimately, advocating for the integration of clustered nursing care in NICUs, with its capacity to deliver superlative care, becomes indispensable in safeguarding the well-being of these vulnerable infants and securing a healthier prospect through refined sleep quality.
