Babies with mucus and milk flaps in their stools are usually considered to be related to indigestion, enteritis or dysentery. If the baby does not have a fever, is in good spirits, does not vomit, and has a small number of stools, it is recommended to stop supplemental feeding in this case, breastfed babies can continue to nurse, and artificially fed babies are recommended to switch to diarrhea formula. Breast-feeding mothers should pay attention to their diet, not to eat greasy, stimulating cold things, and give their babies probiotics, as well as stool tests to rule out bacterial infections. If the stool routine has more than 5 white blood cells, it is recommended to add antibiotics and separate the antibiotics from the probiotics for 2 hours. If the baby has fever, temperature repeatedly exceeds 38℃, poor mental state, accompanied by vomiting more frequently, or with symptoms of dehydration, it is recommended to go to the pediatrician for a face-to-face consultation, routine blood tests, and better treatment by infusion.
