question: My son is 22 months and has had diarrhea for two weeks now. Currently, I change 15-20 diapers a day. His stool ranges from liquid to super soft. He also has been having a lot of mucos in the stool. I ve also noticed tiny, soft gel looking like pellets in his stool. In addition, when his stool is on the soft side versus running, it is brownish, reddish.
