This question already has an answer here:
I'm curious if the order implies anything here. I'm pretty sure "Mom and Dad" is standard in English. The issue was hard for me to google, so I'm asking it here:
Is using "Dad" before "Mom" incorrect, or is it just not often seen/bad practice? I see both, but "Mom and Dad" is far more prevalent.
Edit: What puzzles me is that usually masculine comes before feminine. The given umich article on word order is quite instructive, and I have yet to read all of it. In Chinese and I think Spanish, the father comes first usually.
Now that I think of it, I think German features "Mutter & Vater" more often. Probably carried over into English.
Edit 2: Some power googling reveals that "Mom and Dad" is far more prevalent during 2005-2013.
It can make a difference though, as in an example I found: "I became my girls’ Dad and Mom when one was four years, the other three months old." This is quite clearly in the voice of the father, as shown here.
