Rooming-In and Breastfeeding Duration in First-Time Mothers in a Modern Postpartum Care Center.

Uncertainty concerning the associations between rooming-in and breastfeeding duration remains at postpartum care centers. This cross-sectional study investigated the associations between the rooming-in policy and continual exclusive breastfeeding among first-time mothers at a postpartum center. Of the 160 participants, only 12.5% ( n = 20) implemented full rooming-in. At 3-month follow-up, 85% ( n = 17) of those individuals were exclusively breastfeeding. At the same time point, no participant practicing partial rooming-in ( n = 140) was exclusively breastfeeding. The generalized estimating equation analysis indicated that full (24 h) rooming-in was statistically associated with continual exclusive breastfeeding 1 month postpartum (odds ratio (OR) = 0.90, p < 0.001) and 3 months postpartum (OR = 0.73, p < 0.001). Significant factors associated with a first-time mother's willingness to practice full rooming-in included vaginal delivery, a prenatal decision to practice breastfeeding, and undergoing prenatal classes on both rooming-in and breastfeeding. Success with continual exclusive breastfeeding in the postpartum period is dependent on full rooming-in. The findings serve as a reference for promoting exclusive breastfeeding for the first 6 months, as recommended by the World Health Organization.
