Background: Early breastfeeding practices are important determinants of later breastfeeding behaviors and can be influenced by multiple factors. Despite the Baby-Friendly Hospital Initiative reported positive influence on breastfeeding initiation, its influence on the association between maternal country of birth and first day in-hospital breastfeeding has not been examined. Research aims: To determine (1) if association between maternal country of birth and first day in-hospital exclusive breastfeeding exists in Portugal and (2) if any association is affected by giving birth in a Baby-Friendly Hospital. Methods: Data were drawn from baMBINO—a longitudinal, 2017–2019 nationwide study designed to assess the perinatal health and healthcare experiences of migrant and native Portuguese women. Data from participants (N = 5,340) were collected during their hospital stay from 32 maternity units. Missing data were handled through multiple imputation. After stratifying by Baby-Friendly Hospital Initiative accreditation, a multivariate logistic regression was performed. Results: First day in-hospital exclusive breastfeeding rates were high among both migrant and native participants (89.2% vs. 87.4%). Migrants were more likely to exclusively breastfeed when compared to natives (OR = 1.19, 95% CI [1.00, 1.41]). In non-Baby-Friendly Hospitals, a positive association was found between participants from Eastern European countries (aOR = 2.46, 95% CI [1.27, 4.78]) and first day in-hospital exclusive breastfeeding. In accredited hospitals, maternal country of birth did not influence exclusive breastfeeding during the first 24 hr. Conclusions: The Baby-Friendly Hospital Initiative attenuates differences between migrant and native participants, promoting optimal breastfeeding practices among natives.
