<s>[INST] My 10 month old has been having very loose kind of yellow almost like cottage cheese sour smelling poops for the past week. We had started him on homo milk two weeks ago after he had a case of diarrhea. A few days later our whole family got the 24 hour stomach bug and he threw up twice the one day and again the next day and had non stop diarrhea after that for 3 days we had him on pedialite for four days and the diarrhea never stopped so we put him back on formula. Since then hes only had these loose sour smelling poops. [/INST] Hello. I just read through your question. It seems he may have picked up the stomach bug the rest of the family had. I agree with what you did, and I also agree about putting him back on the formula. The most important thing is to make sure he stays well HY Chat Doctor.  If he is producing 1-2 wet diapers per 24-hour period, you know he is. Otherwise, as long as he is comfortable, you may continue with the current diet. The diarrhea will resolve on its own within a few days. </s>
