Role of Soy-Based Nutritional Extract in Enhancing Breast Milk Production After Childbirth

Exclusive breastfeeding refers to feeding infants solely with breast milk, without introducing any other liquids such as formula, juice, honey, or water, and without solid foods such as bananas, papaya, powdered milk, biscuits, porridge, or mashed rice. The investigation will be conducted during the period of June to July 2025 at the operational area of UPTD Kedaton Health Center, Cirebon Regency. The research applied a quasi-experimental approach, a method designed to identify cause-and-effect relationships between two variables through deliberate intervention while reducing or eliminating potential confounding influences. According to the Mann-Whitney test, soy milk significantly influenced breast milk production, as evidenced by a p-value of 0.028 (< 0.05). The study concluded that the administration of soy milk has a significant positive effect on breast milk production among postpartum mothers.
