Exclusive breastfeeding for less than 6 months contributed to the 1,4 million deaths of infants and 10% toddlers’ morbidity. Perceived Insufficient Milk (PIM) became one of the main causes of exclusive breastfeeding failure in the world. PIM could occured by inability of pregnant women to achieve the recommended weight gain thus mothers have the risk of giving birth of low birth weight (LBW) infants and have low fat reserves to produce milk. Low production of breast milk will negatively affect the confidence of mothers to breastfeed. This study aimed to examine three studies that analyzed the relationship between maternal nutritional status and PIM. The study was conducted in three places Karawang district, Tanjung Priok subdistrict, and Cilandak sub district in 2010 and 2011. The results of this study showed significant associations between maternal nutritional status and PIM with odds ratio (OR) 3,7 (1,47 to 9,08); 3,9 (1,55 to 9,83); and 4,5 (1,86 to 11,01) respectively. It concluded that PIM was experienced by breastfeeding mothers whose maternal weight gain during pregnancy did not achieve the recommendation and caused the mother to stop exclusive breastfeeding. This discovery is important and useful to change the existing perception among breastfeeding experts and communities all mothers, regardless their nutritional status, are able to breastfeed exclusively. The study is expected to provide input for policy makers to pay more attention to the nutritional status of breastfeeding mothers.
