How to diagnose and treat a fever in a child

Typically, people diagnose fever by determining body temperature. You can measure your baby’s temperature by using a thermometer. If possible, mercury thermometers should not be used because they are fragile and can be toxic to the baby’s body. Parents can place a thermometer under their tongue for 2-3 minutes or pin the thermometer to their armpits to determine the temperature.

Check your baby’s body temperature carefully to find the source of the fever to treat your baby promptly.

How to care for children with a fever at home

Parents should identify three goals for caring for a baby at home: controlling temperature, preventing dehydration, and monitoring the serious illnesses that cause a fever that can be life-threatening.

Temperature control

The first goal is to control the baby’s body temperature. Make your baby comfortable by taking a warm bath or wearing appropriate clothes for your baby. The temperature can drop below 38.9 degrees Celsius. Parents can control the baby’s body temperature with a thermometer.

Besides, parents can use some medicines to reduce a child’s fever under the guidance of a doctor, such as:

Acetaminophen (Tylenol and Tempra for children) and ibuprofen (Advil children, Motrin children) are used to reduce fever. The medication should be used for at least 24 hours so that the fever does not return.

Do not use aspirin to treat fever in children, especially for a fever related to chickenpox or other viral infections. Aspirin can cause liver failure in some children.

Prevent dehydration

When having a fever, the baby’s body easily dehydrates the skin and lungs. Encourage your child to drink filtered water (say no to caffeine). Mothers can also prepare chicken soup to hold water for babies.

Supervise the child’s signs

Let your child drink enough water and reduce their body temperature to below 39 degrees C. If both of these measures are applied and the baby is still sick, a more serious problem may exist.

What should children eat when fever?

When your baby has a fever, parents should supplement foods with high-calorie content, high protein, low fat, and a reasonable water supply regime.

The first two or three days can give your baby plenty of fluids like soup, juice, or milk (if there is no diarrhea). Divide the meal about 2 hours/meal after that can gradually increase to 4 hours/meal.

Provide children with soft, light, easily digested, and easily absorbed foods such as porridge, cereals, milk, and soft fruits such as bananas, papayas, oranges, etc.

The amount of protein in the diet should be increased. So parents should supplement foods with high protein values ​​such as eggs, milk, …

Fatty foods, spicy foods, and fiber should be avoided.

The addition of nutrients is also important in fighting a fever. Supplement Vitamin A, B, C, Canix, Iron, and Sodium for babies.


Wearing too many clothes or a very warm blanket can cause a rapid rise in body temperature. However, wearing thin clothing can make your body cold, forcing your body to produce more heat.

So you should choose clothes according to the surrounding temperature, and they need to be airy and comfortable to help the blood flow.

Bathe or soak in warm water

Instead of applying cool compresses to lukewarm water, moms can also quickly reduce fever for children by bathing or soaking in warm water for 10-15 minutes. Do not use cold water because it will cause chills and fever higher due to peripheral vasoconstriction mechanism. Mom can add a few drops of lavender essential oil to create a sense of comfort for children.

Apply warm compresses or warm baths

Many people still believe that cold compresses help reduce fever more easily. This can cause “cold burns” for patients, which is very dangerous if it is a child or infant. Therefore, you should apply warm compresses to your armpits, forehead, neck, or a warm washcloth over the patient.

 Taking a warm bath or showering in the tub will help you relax and reduce fevers very effectively. However, you should not apply this method to young children or infants!

If your body temperature is above 38.5 ° C, you should take a fever-reducing pill, and apply the same way to reduce fever.

If the fever is too high (above 39 ° C), especially for children, it is necessary to quickly bring the patient to the nearest medical facility for examination and treatment by doctors.

Some note:

Do not force children to eat if the child does not like

Give your baby a lot of rest

Give me a sponge bath at room temperature

Wear lightweight clothes

Keep the baby’s room cool, well ventilated, and not too cold or too hot.

Wash your hands with soap and water

Wash food before processing

Vaccination on schedule
