If the child’s fever is already in a stable period, it is not recommended to cover the child. If your child has a fever and is experiencing a rapid rise in body temperature, accompanied by pallor, shivering and other discomforts, in this case, you can appropriately cover your child and pay attention to warmth, which will help to avoid further aggravation of the above symptoms.
