HI, if all else fails, you could use a forehead thermometer, but it's hard to keep the child still for long enough to get an accurate temperature. If your child is feeling really hot (hotter than normal) then I would say that they have a temperature and you may not need to know exactly how high. You know your child and how they normally feel.

hi i'm not sure but i think under the arm or mouth is fine. to be honest it's def. worth investing in an ear thermometer as they are super quick to use whereas with under the arm or in the mouth you have to keep it there for at least a minute and if they are ill then you'll struggle to get an accurate reading as they are unlikely to sit still. x
