<![CDATA[Introduction: Suboptimal milk production is often the reason why mothers stop breastfeeding, one of which is due to the lack of proper stimulation of the breasts. Breast massage, such as lactation massage, has been proven to stimulate the prolactin and oxytocin hormones that play a role in milk production and secretion. This study aims to determine the impact of breast massage training on the process of breast milk formation in third trimester pregnant women. Methods: This study used a one group pre-test and post-test design with pre-experimental quantitative methods. The sample consisted of 23 third trimester pregnant women who were selected using purposive sampling technique. The research was conducted at the Sulili Health Center, Pinrang Regency, in August-September 2024. Data were collected through questionnaires, skill checklists, and observation of colostrum production before and after training. Data were analyzed using the Wilcoxon non-parametric test. Results: The results showed a significant increase in mothers' knowledge and skills after breast massage training. Before the training, all respondents had low knowledge and moderate skills. After the training, 100% of respondents reached the high knowledge and skill categories. In addition, colostrum production increased significantly, from 0% before training to 88% after training. Conclusion: Breast massage training is effective in improving knowledge, skills, and colostrum production in 3rd trimester pregnant women. It is expected that this training can be integrated in routine health education programs for pregnant women to support successful breastfeeding.]]>
