Our first pedi with ODS always said rectally. That is the most accurate way. Our current pedi says under the arm, add a degree and if it is over 100 then you take it rectally. You just insert the silver tip in. Use some Vaseline or KY or something on the tip. Don't add or subtract anything. The ear and forehead thermometers used at home are not accurate/consistent.
