The Indonesian government, WHO and UNICEF recommend exclusive breastfeeding for the first six months of life. Not only for babies, but breastfeeding is also beneficial for mothers, including helping delay pregnancy, accelerating health recovery and providing positive psychological effects. However, one of the obstacles to exclusive breastfeeding is the problem of working mothers. This study aimed to explain exclusive breast milk by working mothers as a new habit. This study is a literature review with the stages of problem formulation, literature search, data extraction, data analysis and interpretation. However, it is proven that many working mothers experience success in exclusive breastfeeding. Good management is one of the keys. The motivation of mothers and families must be built from an early age. With the right education, the knowledge and attitudes of mothers and families on the importance of exclusive breastfeeding can be realized.
