Myself and my 1 year old have been ill for about week starting off as just a cold but getting worse (temperature, vomiting, migraines etc). Doing her temperature the last few days and certain parts of her forehead are fine and one particular spot is high. I'm using one of those electric thermometers and I know they're not very accurate but when I do it to myself or anyone else it doesn't change on different parts of the head?
