Normal stools for an 8-month-old baby should be yellow or golden-colored soft stools or thick stools. If your baby has green loose stools, it suggests the presence of gastrointestinal tract dysfunction, and most of the time, green stools suggest the presence of poor digestion or catching a cold, and so on. At this time, you can give your baby oral probiotics to regulate the micro-ecological environment of the intestinal tract, which can help promote digestion and improve stool properties. At the same time, because of the thinning of the stool, you can give your baby oral Simethicone, also known as Montelukast to protect the intestinal mucosa, which helps to form a layer of protection in the intestinal tract, to avoid further damage caused by pathogenic factors. When using the medicine, it is recommended to apply Simethicone on an empty stomach, and 8-month-old babies can take 1/3 bag each time, 3 times a day, about at least half an hour interval before giving the baby probiotics, the effect can be a little better. In addition, if breastfeeding, the mother’s diet must pay attention to, avoid eating too much greasy food, at the same time the baby’s abdomen must pay attention to keep warm, do not catch cold.
