This study aims to evaluate and compare the effects of two different kangaroo care (KC) models on pain management in neonates undergoing phototherapy. Specifically, the research investigates the impact of mother-administered versus nurse-administered kangaroo care on pain levels during mandatory heel-stick blood sampling. The study seeks to determine which provider model is more effective in reducing procedural pain for these vulnerable newborns, thereby optimizing comfort and care protocols during phototherapy treatment.
