To do a warm compress all you need to do is: 1  Take a clean and soft cloth and dip it in hot water. 2  Ensure the water is not too hot but a little more than warm. 3  Rinse the cloth. 4  Hold this warm cloth gently over your childâs sty for about five to ten minutes, depending on how comfortable your child is. 5  Do this a few times a day.
Rule #2: When abbreviating academic degrees and professional designations, use a period between each letter or element in the abbreviation. No internal spaces are necessary.
The general rule is that you should not use an apostrophe to form the plurals of nouns, abbreviations, or dates made up of numbers: just add-s (or-es, if the noun in question forms its plural with-es).
