The possible causes of green stools in a two-month-old baby need to be analyzed, and the way to deal with them is not exactly the same. If your baby’s overall milk intake is not enough, and he or she does not eat enough or too much, the stool will easily turn green, so pay attention to enhancing nutrition and ensuring milk intake. If the green stool is caused by cold, pay attention to the baby’s abdomen and lower limbs to keep them warm and avoid getting cold, so as to reduce the greenish stool caused by rapid intestinal peristalsis. If the baby is breastfed and the mother has a special diet and eats food that is not easy to digest, the baby’s stool can also be green in color. If your baby has green stools and also changes in stool status, such as mucus, foam, pus and blood, you need to consider your own indigestion or need to exclude the cause of infection, before doing routine stool examination to determine the infection, you can take oral probiotics to regulate the intestinal microecology.
