Ice-cream is not recommended for 3-year-old babies with fever to avoid causing gastrointestinal discomfort. Fever in 3-year-old babies is usually associated with viral or bacterial infections. When in a feverish state, it may affect the gastrointestinal system, resulting in weakened digestion and absorption ability of the stomach and intestines, which may cause significant gastrointestinal discomforts, such as nausea, vomiting, abdominal pain, bloating, etc., after consuming ice-cream. Therefore, when the baby has a fever, parents are advised not to give the child ice-cream, or other cold and greasy food, but to eat a light diet with small meals, and to ensure adequate water intake every day. Parents are advised to take their children to the doctor for appropriate examination and treatment if the fever persists, so as to avoid continuous aggravation of the disease.
