Please clean the end of the thermometer with rubbing alcohol or soap and water. Rinse it with cool water. Do not rinse it with hot water.
Put a small amount of lubricant, such as petroleum jelly, on the end.
Place your child belly down across your lap or on a firm surface. Hold him by placing your palm against his lower back, just above his bottom. Or place your child face up and bend his legs to his chest. Rest your free hand against the back of the thighs.
With the other hand, turn the thermometer on and insert it 1/2 inch to 1 inch into the anal opening. Do not insert it too far. Hold the thermometer in place loosely with 2 fingers, keeping your hand cupped around your child’s bottom. Keep it there for about 1 minute, until you hear the beep alarm.Then remove and check the digital reading.
Pls be sure to label the rectal thermometer so it's not accidentally used in the mouth.
2.You can test your oral temperature
Once your child is 4 or 5 years of age, you can take his temperature by mouth. The following is how to take an oral temperature:
Clean the thermometer with lukewarm soapy water or rubbing alcohol. Rinse with cool water.
Turn the thermometer on and place the tip under your child’s tongue toward the back of his mouth. Hold in place for about 1 minute, until you hear the “beep.” Check the digital reading.
For a correct reading, wait at least 15 minutes after your child has had a hot or cold drink before putting the thermometer in his mouth.
your child feels warmer than usual, you do not necessarily need to check this temperature unless he has other signs of illness.
3.You can test your underarm temperature.
