Globally in 2020, 149.2 million (144.4 to 154.2 million) children under the age of 5, or 22.0% (21.3 to 22.7) of all children under five, are estimated to be stunted (too short for their age). The cause of children experiencing stunting is a multidimensional factor, namely malnutrition experienced by pregnant women and toddlers. This study aims to describe the causes of stunting in toddlers. Subjects and Method: This was a qualitative study with a case study approach.

Data collection was carried out using interviews, observation, and documentation. Data were analyzed using the Miles and Huberman. Results: Parents' education level, toddler's age, toddler's weight, toddler's height, role of health personals in terms of services, exclusive breastfeeding, provision of complementary foods, level of food diversity, sanitation, infectious diseases are factors causing stunting cases in Jombang Regency, East Java.
