Childhood diarrhea is a manifestation of acute gastroenteritis. During this process, his digestive function will definitely be affected, so it is important to pay attention to diet. Provide light and easy-to-digest foods. If breastfeeding, the mother's diet should also include light and easy-to-digest foods. For babies fed with formula, we can use diarrhea-specific formula, and supplementary foods such as rice porridge and noodles can be added. Avoid greasy, spicy, and irritating foods. It is appropriate to add vegetables, but do not orally administer sugary foods, including sugars, biscuits, etc., as these are not suitable for the baby.
