<![CDATA[Insufficient breast milk production remains a major challenge during the postpartum period and may contribute to early discontinuation of exclusive breastfeeding. Non-pharmacological interventions that are safe, accessible, and applicable in maternal healthcare settings are needed to support improvements in lactation. Woolwich massage has been proposed as a supportive technique to stimulate physiological mechanisms associated with breast milk production; however, evidence regarding its effectiveness in specific postpartum care settings remains limited. This study aimed to evaluate the effectiveness of Woolwich massage in increasing breast milk production among postpartum mothers at KRI Madinah Pujon. A quasi-experimental study with a two-group pre-test and post-test design was conducted among 30 postpartum mothers. Participants were selected using quota sampling and divided into an intervention group that received Woolwich massage and a control group that received standard postpartum care. Breast milk production was assessed before and after the intervention. Data were analyzed using the Wilcoxon Signed-Rank Test at a significance level of p < 0.05. The findings showed an improvement in breast milk production following the Woolwich massage intervention. The mean production score increased from 9.377 before intervention to 11.310 after intervention. The Wilcoxon analysis demonstrated a significant difference between pre-test and post-test measurements (Z = −4.787; p < 0.001), indicating that Woolwich massage was associated with increased breast milk production among postpartum mothers. Woolwich massage represents an effective complementary intervention to support breast milk production during the postpartum period. The findings highlight its potential for integration into postpartum breastfeeding support programs as a practical, non-pharmacological approach to improving lactation outcomes. Further studies with larger sample sizes and rigorous experimental designs are recommended to strengthen the evidence for its clinical effectiveness.]]>
