When President Barack Obama was elected, he said he and his family had to convince his mother-in-law to move to Washington. He encouraged her to try it for three months. A year later, it looks like she's staying put.
Robinson, who is widowed, spends much of her time looking after her granddaughters-- taking Malia, 11, and Sasha, 8, to school almost every day. But she has also made a place for herself in D.C., making friends and inviting them over the White House.

Robinson is often seen out and about shopping on her own, at the Kennedy Center, or with the first family at events.
