In general, the course of rotavirus enteritis has three 2-3 day periods of change. First 2-3 days: fever, vomiting, and egg-flake soup-like stools. The second 2-3 days: more frequent diarrhea, up to 7-20 times per day. The third 2-3 days: alternating period, with normal stools alternating with egg-flake soup-like stools. This disease is self-healing when the time comes, and treatment is mainly to address dehydration, electrolyte disturbances, and damage to the heart muscle and liver combined. Your baby must drink more water, and for diarrhea, you can take Siliancon (1 capsule each time, three times a day); and whole intestine (1 capsule each time, twice a day) orally. These probiotics are live bacteria, the main two fears: 1, afraid of heat, you need to use warm water or milk chemical medicine. 2, afraid of oxygen, contact with the air for a long time can be killed by oxygen, so open the package as soon as possible to take. This two points are to be noted.
