This paper explores the sociocultural aspects in the reasons mothers gave for terminating exclusive breastfeeding. These sociocultural aspects were anticipated to influence the variance between actual breastfeeding practice and the current recommendations for exclusive breastfeeding. The complementary feeding patterns and the reasons for introducing complementary foods were assessed using a dietary recall called the Food Choice Map, in a sample of 40 mothers living in a sub-district of South Jakarta. The results showed that the most common reason for introducing first foods in this study was 'insufficient breastmilk'. The influential social factors, including parents, friends and medical professionals were identified. The feeding pattern of the infants in the first six months was highly variable, and commercial baby food was frequently used. We suggest that, even though current exclusive breastfeeding recommendations are beneficial, their promotion should be more sensitive to the social reality of the mothers.
