A 10-month-old baby with a fever of 38 degrees should be undressed appropriately to keep the baby in a cool, comfortable and ventilated environment. Feed your baby milk and water appropriately to avoid dehydration caused by fever. If the baby’s hands and feet are cold with chills, use warm water to soak hands and feet. If the baby is in good spirits, with warm hands and feet and no chills, you can use an ice bag or ice cube wrapped in a towel and apply cold compresses to the baby’s head. If the baby’s temperature rises above 38.5 degrees, take the antipyretic drug acetaminophen orally in a timely manner, giving the appropriate dose according to the baby’s weight. Take your baby to the hospital promptly and ask the doctor to help find the cause of the fever and treat it for the cause.
