I have bought two thermometers so far (a forehead one and an armpit one) and both give such varying readings at any one time that I don’t feel that I can even trust them. Checked my daughter just now and had results ranging from 36.5-37.8 on the forehead one and the armpit one was just as useless.
Can any one recommend a trustworthy thermometer? Don’t want to keep buying ones that are rubbish. Links to exact models would be helpful, thank you.
(For a 6 month old).
We can see this thread is quite old now and some of the suggestions may be outdated, but our best baby thermometer page has lots of great options, as recommended by parents – we hope you find it useful.
