This randomized controlled study aims to evaluate the effect of an animation film on breastfeeding self-efficacy and maternal attachment levels in women with perceived insufficient milk. Women who perceive their breast milk as insufficient often experience decreased breastfeeding confidence and difficulties in mother-infant bonding. The animation film developed within the scope of the study provides information and supportive guidance about breastfeeding. The findings of this study are expected to contribute to improving breastfeeding self-efficacy and strengthening maternal attachment.
