The benefits of breastfeeding are well recognized. However, exclusive breastfeeding (EBF) rates are well below the Healthy People 2030 Guidelines, with a rapid drop in exclusive breastfeeding over the first 3 months of life. Although breastfeeding support has increased the initiation of breastfeeding, the role of perinatal interventions, particularly in the context of breastfeeding support, remains a topic of contradiction. This observational study was designed to assess the impact of a unique prenatal educational intervention in rural East Texas. The study had two aims: (1) to determine whether the addition of prenatal breastfeeding education increased the rate of exclusive breastfeeding at four time points, and (2) to assess the impact of hand expression education on breastfeeding exclusivity. Differences in breastfeeding behaviors were seen between those who received the education and those who did not for exclusivity and duration of breastfeeding. Participants who received the hand expression education were 1.79 times more likely to continue EBF practices at three months postpartum, 6.27 times more likely to continue EBF practices at six months postpartum, and 3.34 times more likely to continue breastfeeding at twelve months postpartum than those who did not receive any hand expression education. This study demonstrates that prenatal education is beneficial for increasing breastfeeding exclusivity and duration and underscores its potential to improve maternal and infant health outcomes. Further research is needed to resolve the ongoing debate and advance our understanding of interventions to increase breastfeeding duration.
