The purpose of this study was to analyze the relationship between the initial age of complementary feeding and the nutritional status of children aged 12-24 months. This type of research is quantitative with an observational analytic approach with a cross-sectional research design. The study was conducted in the village of Padanglampe, Pangkep Regency. The population is all young children aged 12-24 months, the sample is 70 people, and the total sampling technique is used. Nutritional status data were collected by measuring body weight using a scale and anthropometry using Microtoice to measure TB. The data were processed using the SPSS program and analyzed univariately to determine the frequency distribution, and bivariate analysis using the chi-square test. The results of the bivariate analysis showed that there was no effect between the initial age of complementary feeding and the nutritional status of children under five with a p-value = of 1,000. The research suggests that mothers under five should pay attention to the beginning of giving complementary feeding by WHO recommendations, namely 6 months because when babies are 6 months and older their digestive systems are relatively perfect and ready to receive solid food.
