Some of causes of stunting are the deferment of early breastfeeding initiation and the administration of the non-exclusive breastfeeding. The objective of this study was to elaborate relationship of early breastfeeding initiation and exclusive breastfeeding administration history to the stunting. This sudy used the observational analytical research method with the cross-sectional design. Its subjects were 33 stunting and 77 non-stunting children aged 6-24 months in Boyolali Regency. Data was analyzed by using the chi-square test and multiple logistic regression analysis. The stunting children who got the early breastfeeding initiation were 14, and those who did not get the early breastfeeding initiation were 19. The stunting children who got the exclusive breastfeeding were 4 and those who did not get the exclusive breastfeeding were 29. Early breastfeeding initiation and exclusive breastfeeding had a significant correlation with the stunting as indicated by the p-value <0.05. The children who did not get the early breastfeeding initiation have the possibility of 3.69 times higher to suffer from stunting than those who got the early breastfeeding initiation. In addition, the children who did not get the exclusive breastfeeding have the possibility of 9.5 times higher to suffer from stunting than those who got the exclusive breastfeeding.
