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.
Or are you saying id (lower case i, lower case d). If it's id (both lower case) as an abbreviation for idem, you do not use a period after the period. The only instance in English that I am aware of when you use two consecutive periods is a 4-dot ellipsis when the ellipsis is at the end of the sentence. Source(s): Mamie Â· 6 years ago. Thumbs up.
