Question
My child is now six months old and their stool has recently turned green and loose, with milk residue. Additionally, the child has been experiencing high fever every afternoon after waking up from a nap, but there are no issues in the morning. We haven’t started treatment yet, and I would like to know what this situation is and how to handle it.
Answer
It is a normal physiological phenomenon for a baby to have green stool at six months old. This could be due to bilirubin oxidizing in the air, turning into green. Bilirubin originally makes the stool yellow, but after hydrolysis, it forms biliverdin, causing the stool surface to appear green. Moreover, due to the action of bifidobacteria, the intestines become acidic, and the stool is hydrolyzed in the intestines, turning green before being excreted. Therefore, green stool is not abnormal and is a normal occurrence; there is no need to worry.
