Did you know it is important to periodically measure your baby’s body temperature? And, getting an accurate reading is crucial. The conventional mercury thermometer is risky to use with children. A digital thermometer is a good replacement because of its safety and accuracy. But can it be used the same way as a mercury-based thermometer? How does one use a digital thermometer to measure temperature in babies?
What Are The Types Of Digital Thermometers?
The type of digital thermometer depends on the part of the body where the temperature is checked (1).
- Standard multi-use digital thermometer: It is a regular digital thermometer with a metal tip that contains a heat sensor attached to an LCD screen. The screen shows temperature up to decimal points for accurate reading. It is used for oral (mouth), rectal (rectum), and axillary (armpit) temperature measurement.
- Tympanic (ear canal) digital infrared thermometer: This thermometer is used exclusively for ear canal temperature. It uses infrared beams, which detect heat levels through a sensor and display it on the LCD screen.
- Temporal artery (forehead) digital infrared thermometer: The thermometer is shaped in a way that it can be easily placed on a child’s forehead. It uses an infrared beam to measure the temperature of the blood flowing in the temporal artery of the forehead.
Digital thermometers are better than the conventional thermometers as they give an accurate reading and are safe due to the absence of mercury and glass. The American Academy of Paediatrics recommends the use of a digital thermometer for babies.

Age Guidelines To Measure Temperature:
The way you take the temperature depends on the baby’s age (4).
- Three months and below: Only a rectal temperature measurement.
- Between three and six months: You can continue using rectal temperature measurement, and you can also use axillary and temporal artery measurement.
- Between six months and four years: Do an axillary, temporal artery, and tympanic temperature measurement. Rectal can also be used if the child is an older infant.
- Above four years: Oral temperature reading will suffice and will provide an accurate temperature reading.
What Is The Normal Temperature In Infants?
According to the American Academy of Paediatrics, the normal body temperature in babies is between 97.5ºF (36.4ºC) and 99.5ºF (37.5ºC); 100.4ºF (38ºC) and higher is considered a fever (5).
How To Measure Baby Temperature With Digital Thermometer?
Here is how you can measure the baby’s temperature using a digital thermometer.
1. Rectal(Rectum) opening temperature
It is the most accurate mode of measuring body temperature as it shows the slightest of temperature changes. It can be safely done at home.
How to: Use a standard digital thermometer and label it for exclusive rectal use.
- Clean the thermometer with a cotton ball dipped in alcohol and then wipe it dry. Apply some petroleum jelly on the tip of the thermometer as it acts as a lubricant for easy insertion, preventing discomfort.
- Lay the baby on the stomach on your partner’s lap, who should hold the child firmly. You can also put the baby on his back on a soft surface and fold his legs till the thighs.
- Gently spread the buttock cheeks so you can see the rectal opening properly. Slowly insert the thermometer for about half an inch into the anus till you can barely see the metal tip. For babies older than six months, you can insert it to about an inch. Do not go beyond it since it may hurt the baby’s bowel. Premark the thermometer so you know how far to insert.
- Hold the thermometer in position for two minutes until it beeps or till you get a reading on the LCD screen.
- Gently remove the thermometer and note down the temperature. Clean it thoroughly with alcohol before storing it.
2. Axillary(Armpit) temperature
Temperature can be measured by placing the standard digital thermometer in the baby’s armpit. However, this should be avoided in babies younger than three months as the reading would not be precise.
- Undress the baby waist above and hold him in a sitting position. Ensure that the underarm is dry.
- Clean the thermometer with alcohol-dipped cotton and place it in the baby’s underarm.
- Close the forearm and hold the elbow close to the infant’s body.
- Leave it there for five minutes or until the thermometer shows a reading. Note the temperature and clean the thermometer with alcohol.
3. Temporal Artery(Forehead) temperature
Use a digital infrared thermometer for checking forehead temperature.
- Hold your baby in a sitting position.
- Bring the end of the thermometer close to the forehead. Read the instruction manual and follow the procedure as suggested in it. A digital infrared thermometer gives you a reading when you hold it close to the skin and swipe it left to right on the forehead without touching it.
- In the case of a contact-based digital thermometer, gently touch the sensor at the center of the baby’s forehead, press the scan button, and swipe to one side of the head up to the hairline. Release the scan button and note down the temperature reading displayed on the thermometer’s screen.

4. Tympanic(Ear) canal temperature
Never use a standard digital thermometer for tympanic temperature as you could accidentally damage the baby’s eardrum. Tympanic thermometers have to be held in correct position for accurate reading. Excess ear wax could interfere with the measuring process.
- Place the tip of the thermometer at the ear canal as directed in the instruction manual. Insert the tip only till the marking.
- Time taken for measurement will depend on the thermometer and could last from a few seconds to a minute
- These thermometers are sensitive to position, and if you do not place them correctly, you will not get an inaccurate reading. Therefore, take two to three readings for accuracy.
- Do not use ear thermometers in infants younger than six months since their ear canal is too narrow for a thermometer probe.
5. Oral temperature
It is a standard body temperature assessment procedure used for adults as well.
- The child should not eat or drink anything hot or cold for 30 minutes before the temperature assessment.
- Make the child sit in a comfortable position. Clean the thermometer with alcohol and put it between the child’s tongue and lower palate. It should be held in place using tongue and lips, and not teeth.
- At four years, the child is old enough to hold the thermometer by himself if shown the procedure. However, do not leave the child unattended with it.
- Let the thermometer stay for three minutes and then record the temperature. Clean it thoroughly with alcohol and store the thermometer away.

Remember, if you get a reading of 99ºF (37.2ºC) or above in axillary, temporal, or tympanic assessment, then immediately check the rectal temperature to verify if it is high temperature (6).
Points To Remember:
It is important to keep certain points in mind before, during, and after taking the baby’s temperature with a digital thermometer.
- Do not check the temperature after a physical activity and after taking showers as it increases the body temperature and gives an inaccurate reading.
- Always follow the instructions in the product manual.
- Keep the thermometer away from the child’s reach even if he is older than four years to avoid a choking hazard.
- Clean the thermometer thoroughly before storing it away in a clean, cool, and dry place.
When To See A Doctor:
A digital thermometer should give you an accurate reading to determine if the baby has a fever. There are some situations when you must see a doctor immediately:
- The baby is below three months and has a temperature of 99ºF (37.2ºC) or above, measured by any kind of thermometer. Newborns have a developing immune system, which is vulnerable to pathogen attack.
- This makes medical intervention necessary.
- The baby is between three and six months and has a temperature of 100ºF (37.8ºC) or more.
- The baby is older than six months and has a temperature of 102ºF (38.9ºC) or higher. Babies and even older children will show signs of fever such as irritability, lack of interest in food, and chronic lethargy.
- Fever is often accompanied by health conditions such as cold, stuffy nose, or stomach problems such as diarrhea.
