Two-month-old babies with watery stools may be related to improper feeding, bacterial infection, viral infection and so on. 1. Improper feeding: if breastfeeding, if the mother recently ate spicy stimulation, too greasy food, may cause stimulation of the baby’s stomach and intestines, causing the symptoms of dilute watery stools. 2. Bacterial infection: Bacterial infection can cause damage to the intestinal flora, causing diarrhea and watery stools. 3. Viral infections: Viral infections of the baby’s intestinal tract, such as norovirus infection and rotavirus infection, may also cause symptoms of loose stools. There may be other reasons for your two-month-old baby’s watery diarrhea, so we recommend that you go to the hospital in a timely manner, complete the examination to determine the cause of the problem, and then treat the problem under the guidance of your doctor.
