Exclusive breastfeeding is scientifically known to reduce child mortality; however, coverage remains low in Bulukumba Regency, which has the lowest rates in South Sulawesi Province, Indonesia. This study aimed to examine the influence of the Theory of Planned Behavior (TPB) on exclusive breastfeeding behavior among mothers in the region. A quantitative cross-sectional study was conducted with 161 mothers of infants aged 6-12 months. Data were collected using a validated and reliable questionnaire and analyzed using Structural Equation Modeling-Partial Least Squares (SEM-PLS). The findings indicate that maternal attitudes towards exclusive breastfeeding (β=0.619) and perceived control (β=0.338) had significantly positive effects on breastfeeding intention, whereas subjective norms were not significantly associated with breastfeeding intention (p=1.000). Furthermore, attitudes, subjective norms, perceived control, and intentions did not have a significant direct effect on exclusive breastfeeding behavior (p>0.05). The results highlight a gap between intention and actual breastfeeding practice, suggesting that strong intentions alone are insufficient to ensure exclusive breastfeeding. These findings underscore the importance of strengthening maternal attitudes and perceived control while addressing contextual and social barriers to behavior change.
