If there’s no infection, normal stool, and no rotavirus infection, the issue might be related to what the baby ingests. Breastfeeding babies might experience diarrhea due to their mother consuming greasy or cold foods, while formula-fed babies might have issues with unclean water and bottles. Alternatively, it could be due to catching a cold. In such cases, you can try Danggui Er navel sticker and Simeticon or MamiAi, stopping the diarrhea first before addressing the root cause.
