Rectal Temperature

Getting the thermometer ready

• Be sure to use a thermometer that is for rectal use.

• Wipe the thermometer with warm, soapy water, then wipe with clean water. Wipe dry or let the thermometer air-dry.

• Put a small amount of petroleum jelly or water-based lubricant on the tip.

Positioning your baby

Use the position that works best for you:

• Put baby on their back on a firm surface. Hold baby’s ankles and lift both legs, as if changing a diaper.

• Or place baby face down across your lap. Use one hand to part baby’s buttocks.

  

Taking the temperature

Follow the directions for using your specific digital thermometer:

• Gently slip the tip of the thermometer into the anal opening (where stool leaves the body), no further than 1/2 inch to 1 inch.

• Hold the thermometer in place until it beeps. Slide the thermometer out. Read the temperature on the digital display.

• Before putting the thermometer away, clean it with soap and warm water.

• When you report your baby's temperature to the doctor, make sure you include that the temperature was taken rectally.
