ABSTRACT:
Background: Breastfeeding is often conceptualized as a unidirectional transfer of nutrition from mother to infant. However, emerging evidence highlights a complex, bidirectional relationship characterized by mutual physiological and psychological interdependence. Objective: This paper examines the dynamic interplay between mother and infant during breastfeeding, emphasizing how both mother and infant actively shape and benefit from this dyadic process. Methods: This paper synthesizes evidence from lactation physiology, neuroendocrinology, and attachment theory to elucidate the mechanisms of breastfeeding interdependency. Key Findings: The infant regulates milk production through suckling efficiency and feeding cues, while maternal factors (hydration, stress, responsiveness) directly influence milk composition and ejection. Oxytocin-mediated emotional bonding during feeding enhances maternal-infant attachment and may reduce postpartum depression risk. The relationship evolves as both partners adapt, fostering infant emotional regulation and maternal caregiving confidence. Conclusion: Breastfeeding represents a co-created biological and emotional partnership. Clinical practice should prioritize supporting this dyadic system through holistic interventions addressing both maternal well-being and infant feeding behaviours. Recognizing breastfeeding as interdependent—rather than mother-centric—can optimize lactation outcomes and attachment quality.
