Are you supposed to get plastic covers for this when using for rectal?
Sarah L

Best Answer:  No. The Frida Baby 3-in-1 True Temp Thermometer is designed to be used without disposable probe covers for rectal, oral, or underarm temperature readings. The instructions recommend lubricating the tip for rectal use (for example, with coconut oil or another water-safe lubricant), then cleaning and disinfecting the thermometer thoroughly after each use.

Worst thermometer ever used.
This is the worst, least reliable thermometer we’ve used. It can’t read most of the time and when it does it is inconsistent.

Do not buy this
I added this to my registry thinking Frida is a pretty trustworthy brand. My 8 week old was extra sleepy and not wanting to eat as much so figured I'd take her temp. Three times, twice rectally for best accuracy and once in the armpit all read 94-95. Called my pediatrician obviously and they made me hang up and call paramedics. They took her temp and blood sugar and all was normal. Read the other reviews and beware- I'm one of several parents who had to seek emergency intervention due to this faulty thermometer.

Significantly inaccurate.
Consistently 3-4 degrees low. Compared with another thermometer that I know is accurate. My baby had a 100 degree fever and it read as 97.4.

Dangerously inconsistent and inaccurate readings
Dangerously inconsistent and inaccurate readings. The ear would read 97.8 and then on one part of forehead it read 98.9, another 101.4. For use on child or infant, you can see how gravely problematic this could be. I should have read more reviews before purchase, as this appears to be a known problem with these thermometers.

Do not buy. Low temp readings!
Don’t buy. Temp reading is so low. Made me panic as a newborn mom when I saw consistent 95.5 readings. Took it to the pediatrician appointment to compare to the doctor’s, and the doctor’s thermometer read normal, 98. Threw it away.
