The percentage of exclusive breastfeeding in Indonesia is still quite low, which is only 37.3%, followed by 9.3% partial breastfeeding and 3.3% predominant breastfeeding. This is motivated by mothers who give other types of food to babies. Low breastfeeding will affect the incidence of diarrhea in children aged 0-24 months. In Indonesia, the Ministry of Health of the Republic of Indonesia supported by the Indonesian Doctors Association has issued a guideline to reduce diarrhea rates, namely the Five Steps to Complete Diarrhea. A program consists of giving zinc for 10 consecutive days, fluids, selective antibiotics, advice to the patient's family, and breast milk and food.
