At two months old, the baby’s stool test revealed white blood cells and hidden blood. After taking probiotics and montmorillonite powder for three days and probiotics for six consecutive days last month, the baby’s stool returned to normal and they no longer had diarrhea. However, this month, when rechecked, in addition to the continued presence of white blood cells, red blood cells and hidden blood were also found. What should I do? The doctor only suggested observation and did not prescribe any medication. In recent days, the baby has been making rumbling sounds in their stomach, and today they had diarrhea three times.
