Diarrhea during breastfeeding has certain effects on the baby. Diarrhea during breastfeeding is related to many factors, some of them are caused by cold in the abdomen or eating greasy food, this situation does not affect the baby much and can continue to breastfeed. However, some women have diarrhea caused by bacterial infections in the intestines, which can lead to some of the bacteria entering the baby’s digestive system through lactation, which can affect the baby’s health and lead to diarrhea symptoms in the baby as well. For diarrhea caused by viral infections, breastfeeding should be stopped for a period of time and treated with medication as soon as possible. Antibiotics should be avoided because they can be secreted through the breast milk and affect the baby’s health. During the use of antibiotic medication, breastfeeding should be continued only 48 hours after the medication is stopped to reduce the impact on the baby’s development.
