It is generally not recommended to drink milk when you have diarrhea, because milk contains a lot of fatty substances, which, after entering the body, will stimulate the stomach and intestines and increase the peristalsis of the gastrointestinal tract, thus aggravating diarrhea. In case you can’t drink milk, you can replace it with other dairy products, such as yogurt. In the case of lactose intolerant infants and children, the usual diet should be based on zero lactose dairy products. When a child has diarrhea, it is generally recommended to drink more starchy foods such as rice and noodle soups. For small infants, it is recommended to feed rice paste, rice oil and other types of food. At this time, it is not recommended that the affected child eat foods that are difficult to digest, and it is also not recommended to wean at this time. Usually, mothers are advised to eat more rice soup and noodle soup to increase the secretion of milk. At the time of diarrhea, there is usually no problem as long as the child’s fluids enter, even if fasting for 4-6 hours. For adding complementary foods, it is not recommended to add new complementary foods to the child at this time to prevent aggravating diarrhea symptoms. If the child appears to have vomiting, crying, sunken fontanelle and other serious symptoms, parents must promptly take him/her to the doctor.
