D.F.
I have a temperature chart that came with my Safety 1st ear thermometer that says:
Normal temperature ranges for measuring sites:
Oral: 95.9F - 99.5F
Rectal: 97.9F - 100.4F
Ear: 96.4F - 100.4F
Axillary (Under the arm): 94.5F - 99.1F
Ear temperature ranges by age:
0-2 years: 97.5F - 100.4F
3-10 years: 97.0F - 100.0F
11-65 years: 96.6F - 99.7F
Over 65 years: 96.4F - 99.5F
I hope it helps!
