The aim of this scoping review was to explore the evidence related to breastfeeding education in postpartum mothers from relevant databases (PubMed, Science Direct, and Wiley). There were nine eligible studies in which all of them used quantitative design. The data was organized into seven themes including targets, materials, methods, media, officers and places, time, and the effect or influence of breastfeeding education. Almost all (8/9) articles informed breastfeeding education targets. There were 5/9 articles that reported the methods, 6/9 articles discussed the media, 8/9 articles talked about the officers and places, 7/9 articles concerned about the time of implementation, and all studies reported the effect of breastfeeding education. Breastfeeding education included at least 5 existing components. Breastfeeding education must be planned properly and must be carried out continuously from the antenatal until the postnatal period.
