If the stool is watery, or egg-like stool, which occurs in autumn or winter, most of them are caused by intestinal viral infections, the number of stools can be about 10 times a day, and the amount of watery stool ejected is relatively large. As babies lose more water, they often show some signs of dehydration, such as dry mouth, dry tongue, sunken eyes, fewer tears or even no tears, less urine, and less elastic skin. If the stool is green and thin, occurs after weather change, cold or eating indigestible food, and the number of times per day is about 5-10, consider intestinal dysfunction caused by cold. If there is mucus or thick blood in the stool, bacterial enteritis should be considered and should be treated at the hospital as soon as possible.
