Are Mom and Dad capitalized?
You should capitalize “mom” and “dad” when they're being used as proper nouns. The words mom and dad (also grandma and grandpa, et al), should be capitalized when they are used as a proper noun, in place of their given name.
First of all, "proper noun" isn't one. It should not be capitalized. Note that we all agree that Dear Mom or Dear Dad are appropriate when we are using "Mom" or "Dad" as nicknames. If you're using "Parents" as a nickname to address your parents, I suppose you could make a case for it.
