How To Check Your Baby’s Temperature?

Most pediatricians recommended checking baby’s temperature rectally. This method will give you the most accurate result. There are other methods to check baby’s temperature—axillary or forehead. Both convenient methods, but they will not give the same results as rectal temperature checking. It’s better to wait with those methods until baby is a little older.  

Investing in a reliable rectal baby thermometer is a must when you have a baby on the way. You never know when baby gets a fever. Try iProven’s DTR-1221 BLU. It’s inexpensive and designed to check baby’s temperature rectally. With the small, flexible tip, discomfort will be kept to a minimum. 

How to check baby’s temperature rectally? 

Checking baby’s temperature can be a wild ride. Inserting the tip of the thermometer in baby’s rectum is uncomfortable. It sometimes makes baby fuss, protest or even cry. Here are some guidelines to make it a more pleasant experience with the results you need. 

  1. Make sure the thermometer is clean. iProven’s DTR-1221 BLU is waterproof, making it easy to clean it with soapy water. Or use rubbing alcohol. After the tip of the thermometer is cleaned and dried, coat it with the smallest amount of petroleum jelly to make insertion as easy as possible.

  2. Place baby on their back. Lift and bent baby’s legs to baby’s chest. This position is most comfortable for baby since it’s similar to changing the diaper. Try to give baby a toy or entertain baby with silly faces to distract baby during temperature checking. This way, baby is less likely to start fussing and protesting.

  3. Press the button of the thermometer to turn it on. Then, gently insert the tip of the thermometer no more than 1 inch.

  4. Wait while the thermometer checks the temperature. iProven’s DTR-1221 BLU takes only 10 seconds. Hold baby’s legs firmly with one hand while holding the thermometer in place with your other hand. In case baby starts wiggling, you can keep the thermometer in place.

  5. After the thermometer is done, it will beep. Remove the tip and read baby’s temperature. Before storing the thermometer again, clean it thoroughly with soapy water or rubbing alcohol. 

Fever is a common sign of illness and not necessarily bad. However, contact your doctor if baby’s temperature reads 100.4℉ and is younger than 3 months old or if baby’s temperature reads 102℉ and is younger than 6 months old.
