I got one and it's great, it's abit hard to get bub to keep still.
I remember from when the lil man was in the NICU they told us that the only thermometers that are reliable for lil kids under about 3 are the under the arm ones... Their ears are too little to get an accurate scan with the ear ones and the forehead ones are just crap...
Best recommendation is get one that just goes under the arm, yes they tend not to like it but at least its accurate
How underarm one is hopeless. Unless we get it int he exact position needed it gives us a really low reading. And is it true with the underarm ones you are supposed to add .8 of a degree to it?
Ive found the dummy themometers are the best. As long as it isnt taken out of the mouth. itsa the only one that has been reliable (till it got broken sad)
