Girls, hi everyone! It seems like my little one has diarrhea. Yesterday he pooped 4 times, and it's watery stool. I attached photos in the comments, just in case some girls have toxemia. In the stool I found something black (photo 1) and on the second photo there is green stool with white spots, this happened today. Yesterday and today I gave him enterosgel. By the way, we had a bout of chickenpox (we were hospitalized), maybe that's why the stool is green. What should I do? Can you tell me? I'm going to see a doctor tomorrow.
