Children’s temperature measurement (how to measure baby fever):


We must know each method and what is the temperature that needs treatment. Follow us with a detailed explanation of methods for measuring temperature in children:

The rectum (how to measure baby fever):

  • This is the most reliable way to ensure an accurate fever measurement.
  • Clean the thermometer in cold, soapy water and rinse it.
  • Cover the silver tip with Vaseline.
  • Lay your baby on his back with his knees bent.
  • Gently insert the thermometer into the rectum, about 1 inch (2.5 cm) in diameter, holding it in place with your fingers.
  • You will hear a beep after about one minute. Remove the thermometer and read the temperature. Clean the thermometer.

the mouth (how to measure baby fever):

  • The oral method is not recommended for children under the age of 5 because it is difficult for them to keep a thermometer under their tongue long enough.
  • Clean the thermometer in cold, soapy water and rinse it.
  • Carefully place the tip of the thermometer under your child’s tongue. With your child’s mouth closed, leave the thermometer in place for about a minute, until the beep is heard.
  • Remove the thermometer and read the temperature.
  • Clean the thermometer.

Armpit (how to measure baby fever):

  • The armpit method is usually used to check for fever in newborns and toddlers, but it is not as accurate as the rectal temperature.
  • If the armpit temperature does not show a fever but your baby is feeling warm and seems fine, have a rectal measurement.
  • Use a rectal or oral thermometer.
  • Clean the thermometer in cold, soapy water and rinse it.
  • Place the tip of the thermometer in the center of your child’s armpit.
  • Make sure your child’s arm is stretched tightly against her body.
  • Leave the thermometer in place for about a minute, until you hear the beep.
  • Remove the thermometer and read the temperature.
  • Clean the thermometer.

Ear (how to measure baby fever):

  • Although it is quick to use, the ear method can give very low temperature readings, even when you follow the manufacturer’s instructions.
  • It is not as reliable or accurate as taking a rectal temperature.
  • Use a clean probe head every time, and follow the manufacturer’s instructions carefully.
  • Gently pull the ear, and pull it back. This will help straighten the ear canal and make a clear path inside the ear to the eardrum.
  • Gently insert the thermometer until the ear canal is completely closed.
  • Press and hold the button for one second.
  • Remove the thermometer and read the temperature.

What is the systemic temperature (how to measure baby fever)?

The following chart tells you if your child has a fever. The normal temperature range varies and depends on how your child’s temperature is taken:

  • Rectal method 36.6 ° C to 38 ° C.
  • Oral method 35.5 ° C to 37.5 ° C.
  • Armpit method 36.5 ° C to 37.5 ° C.
  • Ear method 35.8 ° C to 38 ° C.

The degree (high) of a fever does not tell you how dangerous your child’s illness is, the way your child behaves is usually a better sign. A child with a mild infection may have a high temperature, while a child with a severe infection may not have a fever at all.

How should I deal with a fever (how to measure baby fever)?

  • Keep your child comfortable and offer plenty of fluids.
  • If your child has a fever, remove extra blankets and clothing so that the heat will leave his body and help lower his body temperature.
  • Do not take off all of your baby’s clothes, as it may get very cold and start to shiver, which increases the body temperature and causes him to overheat again.
  • Sponging your baby with lukewarm water, alcoholic baths and massages is not recommended.
  • Medicines do not always need to be taken to lower a child’s temperature. In fact, the best reason to give your child medicine is not to reduce the fever, but to relieve any pain.
  • Acetaminophen (such as Tylenol, Tempra, Panadol, and others) is a suitable fever medicine. Unless otherwise authorized by your doctor, you can give the recommended dose on the package every 4 hours until your child’s temperature has decreased.
  • The temperature usually drops within one hour and then rises again. If this occurs, the medication may need to be repeated at the recommended time.
  • Do not give more than 5 doses in 24 hours. Alternatively, you can give your child ibuprofen, which is found in products like Advil and Motrin. Be sure to follow the instructions on the package.
  • Ibuprofen can be given every 6 to 8 hours up to 4 times in 24 hours. Do not exceed the recommended dose.
  • Ibuprofen should only be given if your child is drinking reasonably well. Do not give ibuprofen to children under 6 months of age without talking to your doctor.
  • Do not alternate between the use of acetaminophen and ibuprofen as this can lead to dosing errors.
  • A child or teenager with a fever should not be given aspirin to acetylsalicylic acid (ASA).
  • If the fever is due to chickenpox , the flu, or another viral infection, taking aspirin can increase the risk of Reye’s syndrome. This is a very serious condition that can damage the liver and brain.

When to see a doctor (how to measure baby fever)?

  • If your baby has a fever and is under 6 months old.
  • Has a fever for more than 72 hours.
  • Eccentric, difficult or irritable.
  • Excessive sleepiness, lethargy, or unresponsive.
