What under-the-arm temp is considered to be a fever?

Jazz had 2mo immunisations yesterday (about 11ish), got really cranky, clingy and restless mid-afternoon (though it was extremely hot as well), and had a temp of 38 under the arm last night. We gave her panadol at 9pm to help bring it down, and i took her temp every two hours and by this morning it was 36.5, but has risen to 37.3 again. I'm just wondering, as under the arm temps are usually lower (i think), what is classified as a fever? What is normal under the arm range. I've read 36.4 is normal for under the arm?

I was going to say 37, so 36.4 is probably about right.

I got a great thermometer on ebay for $20. It can either be in the ear or just against bubs skin. item # 260294519321

anything about 37.5 is considsiderd a fever , generally temps taken from the ear /forehead are more accurate as under the arms can be hot due to clothing/hotweather or cooler due to persperation ..

i am soo not looking forward to G's 1st needles ... ouch

At hossy I was told that anything above 37.3 was considered a high temp. That was for a newborn so I'm not sure if it changes when they get older.

dont forget if you do it under the arm you need to add .5 of a degree onto the temp displayed, id give panadol if its over 38 and she needs it but not really under that! the body needs to do its thing and having a temp means its fighting which is what it is ment to do

Up to 37.2 is normal, above that is a temp, but as AJP says, it is now recommended not to give panadol until the temp is higher - above 38.5 or more. However, if she is unsettled and possibly in pain and the panadol settles her, I'd use it for that reason anyway. I hope she is better soon.

I can never tell what is considered to be a temp, and I forget what I have been told. I keep meaning to take bub's temp when she is feeling good and use that as a benchmark.
