Breastfeeding is a natural process. However, in todays environment, doing the natural thing is not always easy, because there are many factors that influence the success of this natural process. To achieve success in breastfeeding, the mothers factors, the babys factors, and the environment must be supportive. If one of them is not fulfilled, the breastfeeding process will not be optimal. Therefore, health workers must highlight not only mothers, but also families, husbands, mothers/in-laws, even community leaders or religious leaders to jointly support and support the success of breastfeeding. Efforts to increase mothers knowledge about exclusive breastfeeding begin during antenatal care and not after delivery, because if it is done after delivery it will be too late.
