It’s official: Marian Robinson, the 71-year-old mother-in-law of President-elect Barack Obama, will be moving into the White House, transition officials said on Friday.

In fact, Mrs. Robinson is already in town, helping to smooth the family’s personal transition as Mr. Obama, his wife, Michelle, and their two daughters prepare for new lives at 1600 Pennsylvania Avenue.

“She is here to help them get up and running,’’ said Katie McCormick Lelyveld, a spokeswoman for Mrs. Obama. “She will determine in the coming months whether or not she wants to stay in D.C. permanently.”

In some ways, Mrs. Robinson’s decision to move – at least temporarily — is no real surprise. During the presidential campaign, Mrs. Robinson was a family mainstay, caring for the Obama girls, Sasha and Malia, while their parents were on the road.

She took them to school, to piano lesson and dance lessons, cooked their meals, ran their baths and got them to bed on time. She was a critical part of the family’s effort to keep the girls’ lives as normal as possible in the midst of extraordinary times.

But Mrs. Robinson is also deeply rooted in Chicago. She still lives in the house where Michelle Obama grew up. And she has often expressed ambivalence about the notion of moving to Washington.

“I’ve never lived outside of Chicago, so I don’t know,’’ said Mrs. Robinson, hesitating a bit as she considered last year whether she was willing to move into the White House. “In the end, in the end, I’ll do whatever. I might fuss a little, but I’ll be there.”
