Background: A mother's knowledge of ANC can increase interest and motivation in carrying out pregnancy checks which aim to detect problems early. Exclusive breastfeeding is one effort that can be made to meet nutritional needs to prevent stunting.
Purpose: Analyzing the correlation between maternal knowledge of ANC, exclusive breastfeeding history, and stunting incidence in Hamlet III, Sukamulya Village.
Method: Quantitative correlational, with a population of 68 families of stunted toddlers living in Hamlet III, Sukamulya Village. The sample size used for the research is total sampling. Secondary data is used for the research with instruments that include a combination of "Environmental Modification through Sanitation, Clean Water, Hygiene and Nutrition for Stunting Prevention" with the research instruments of Khairani, (2012) and Fitriani, (2021). The data analysis method used is univariate and bivariate analysis (Spearman rho).
Results: There was no significant relationship between ANC knowledge and the incidence of stunting, obtained r=0.114 and ρ=0.353. Likewise, exclusive breastfeeding also did not show a significant relationship with the incidence of stunting, obtained r=0.007 and p=0.955.
Conclusion: There is no relationship between maternal ANC knowledge and exclusive breastfeeding with the incidence of stunting.
