A child with a fever and bumps all over the body may have symptoms of toddler rash, whose main symptom is a high fever at the beginning that may also be accompanied by diarrhea and a mild cough. After the fever has subsided, a small rash will appear on the skin, which is caused by a viral infection. First of all, you need to pay attention to scrub your body with warm water to avoid repeated fever; in addition, drink more water, hot water and hot rice soup to make your body sweat, which can promote the discharge of toxins from the body. Eat light, digestible food. Only after the fever is completely cured will the toddler rash recover completely.
