Stunting is a problem of chronic malnutrition due to lack of nutritional intake from birth to the age of two. Of the 11 districts in Jambi, Kerinci Subdistrict is recorded with the second highest prevalence of stunting in toddlers aged 24-59 months, which is 26.7%. A very important factor in the incidence of stunting is the rate of exclusive breastfeeding and adequate nutrition. A case control study, with purposive sampling technique and obtained 184 samples (46 cases and 138 controls), based on sex matching. The independent variables were history of initiation of early breastfeeding, exclusive breastfeeding, and practice of giving complementary feeding (time, frequency, amount, type of basic ingredients, and variety of nutrients), while the dependent variable was the incidence of stunting. Data analysis was performed by Chi-Square and Enter logistic regression method. There was a significant relationship between the history of early initiation of breastfeeding and the practice of giving complementary feeding with the incidence of stunting. The factors that contributed the most were the type of basic ingredients (p=0.004; OR=22.545), the amount (p<0.001; OR=8.115), the variety of nutrients (p=0.006; OR=7.512), and the frequency of complementary feeding (p=0.017; OR=5.059). In preventing stunting it is important to pay attention to the type of basic ingredients used with attention to the nutrients contained. In addition, the frequency and amount are also important to note according to the age of the toddler.
