You do not want something like this on your resume:
Mother of three children: William (born 1992), Kara (born 1994), and Lee (born 1997)
Why is it there?!?! Why?! Why?! Get it off, immediately.
I do not need to know the names and ages of your children, your pets, or your parents. I need to know about your skills and accomplishments. In the professional realm, not the domestic one.
Obligatory disclaimer that we’re talking about the U.S. here and, yes, other countries share all kinds of personal info on their resumes, like spouses, children, health status, religion, and bra size. The U.S. does not, and people whose resumes make it clear that they’ve spent their entire career in the U.S. have no excuse for this sort of thing.
