The aim of this study to assess the characteristics of breastfeeding accompaniment needed by exclusive breastfeeding mothers for the success of exclusive breastfeeding until 6 months. This study used mixed methods, both a cross-sectional survey of 148 mothers breastfeeding infants aged over six months in five PHCs with low level of exclusive breastfeeding coverage and unstructured interviews were conducted by ten PHC midwives in five PHC areas.
