President-elect Barack Obama's mother-in-law, Marian Robinson, is temporarily moving into the White House to join Michelle Obama and her two granddaughters.
She will help 10-year-old Malia and 7-year-old Sasha get acclimated. Also during this time, she will decide if she would like to stay in DC permanently.
Robinson retired from her job as a bank executive secretary last summer to take care of the granddaughters while their parents campaigned.
The white house has a history of also being occupied by many extended families.
