WASHINGTON - Michelle Obama loved Barbie dolls as a girl. She now prefers Christmas without snow, after living most of her life in Chicago. She isn't sure how she'll celebrate her 50th birthday in about a month but says "it might involve some dancing."

Revelations from a new interview with a glossy magazine? Guess again.

The first lady disclosed these tidbits and a few more during an annual holiday visit Monday with patients at Washington's leading children's hospital.

It included a question-and-answer session with the pint-size patients, 14 questions in all.

"I don't take questions from the press. They will tell you that," Obama replied to one questioner as she sat in front of a towering Christmas tree in the atrium of Children's National Health System.
