Background and Objectives: Although breastfeeding is recommended by WHO, the breastfeeding rate in Indo- nesia remains low, because many women fail to maintain their breastfeeding intention during the breastfeeding period. The decision whether to breastfeed or not, like any other nutritional behaviour, may develop over a life- time and is rooted in many aspects of life; however, many factors may affect a mother’s decision about whether to stop or continue breastfeeding during the breastfeeding period. A critical time point of contact for breastfeed- ing is a time point when the mother experiences difficulties and encounters influences that may affect breastfeed- ing continuation. Methods and Study Design: A qualitative approach was used to investigate the factors affect- ing breastfeeding intention and continuation. A follow-up approach was used to assess actual experiences and problems at each time point of contact. The interviewees in this study were pregnant women who lived and worked in West Jakarta and were in at least Week 36 of their pregnancy. The key interviewees for triangulation were 2 grandmothers and 2 healthcare providers. Results and Conclusions: Knowledge, beliefs, and support were the factors affecting the women’s intentions. Perceived obstacles; common beliefs; stigmas regarding breastfeeding; and support and influences from husbands, mothers, family members, and relatives were the fac- tors influencing breastfeeding continuation within the first month postpartum.
