<![CDATA[Breast milk production in postpartum mothers may be affected by psychological conditions and poor sleep quality, which can influence oxytocin secretion. Husband involvement and spiritual approaches may provide practical and culturally appropriate support during the postpartum period. This study aimed to evaluate the effect of the SPEOS (Endorphin, Oxytocin, and Suggestive Massage Stimulation) method administered by husbands combined with Qur'anic murottal therapy on breast milk production, sleep quality, and psychological condition among postpartum mothers. A quasi-experimental study with a post-test-only control group design was conducted among 98 postpartum mothers recruited through accidental sampling from eight independent midwifery practices in Pringsewu Regency, with 49 participants in each group. The intervention was implemented throughout the first four weeks postpartum and consisted of husband-administered SPEOS massage combined with Surah Ar-Rahman murottal therapy. Data were analyzed using bivariate statistical tests with a significance level of p < 0.05. The results demonstrated significant differences between the intervention and control groups in breast milk production (p = 0.002), sleep quality (p = 0.002), and psychological condition (p < 0.001). These findings indicate that husband-administered SPEOS combined with Qur'anic murottal therapy may improve breast milk production, sleep quality, and psychological well-being among postpartum mothers. This intervention may serve as a feasible complementary approach that promotes active husband involvement in postpartum care.]]>
