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.
Also, we do not use a period with such abbreviations except for in. when it might be confused with the preposition in. When the term of measurement is used as a modifier, we put a hyphen between the number and the term of measurement: a 15-ft board, a 6-lb line, etc.
