Jill Biden's grandchildren are frequent White House visitors.
Some first ladies have raised their families in the White House, moving into 1600 Pennsylvania Avenue with young children who are still in school. Others have become first lady after their children were fully grown, but they remained close with their grandchildren.
In honor of Mother's Day, here's a look back at how motherhood has changed in the White House.

"I remember well my own college years: the good, the bad and the ridiculous," Hillary Clinton wrote. continuing: "I can't imagine having any of those private experiences, all part of finding myself, being interrupted by the bright lights of cameras — and not because of anything I was or did but because of my parents' occupations. I hope Chelsea's college years will be her own, too."
Bill Clinton was president from 1993 to 2001 — his daughter graduated from Stanford that same year.
