Background: Despite increasing interest in responsive feeding, current literature lacks a clear and specific definition of this concept, particularly as it applies to infants under one year of age.<p>Purpose: The purpose of this study was to clarify the concept of responsive feeding in infants under one year old, ad-dressing definitional ambiguities in existing literature.<p>Methods: This study employed Walker and Avant’s concept analysis method, which was applied to a comprehensive literature review about the conceptual framework for responsive feeding. A systematic literature search was conducted across databases including the Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, Med-line, and Google Scholar. Studies published in English between 2000 and 2022 that defined or evaluated responsive feeding were included. Search terms included “infant,” “feeding interaction,” “responsive,” and “reciprocity.”<p>Results: Seventeen original studies focusing on responsive feeding in infants under one year of age were included. Defining attributes identified were: (1) maternal sensitivity, and (2) appropriate responses to infant hunger and sati-ety cues to optimize feeding interactions. Antecedents of responsive feeding included: (1) maternal perception and awareness, (2) maternal beliefs and attitudes, and (3) socio-environmental factors such as cultural context, maternal psychosocial status, and responsive environments. Consequences of responsive feeding were noted at both infant and maternal levels.<p>Conclusion: This concepts analysis article enhances the theoretical understanding of responsive feeding behaviors in early infancy. By synthesizing empirical evidence, the study provides a clearer conceptual framework that may inform future research, clinical assessment, and intervention design.
