altMichelle Obama said that while she has "a lot of fun" in her job as first lady, it's a challenge to raise her children within the bubble of the presidency.

"You absolutely live in a bubble. There's shatterproof glass on our windows, you know, men with guns on the roof and that's just the reality of it," said Mrs. Obama in an interview with Gayle King on "CBS This Morning."

Obama told CBS's King, during a tour of the East wing of the White House, that she has to work to try to maintain a normal life for her daughters, Sasha and Malia.

"I have to keep my kids on track to do things we would do if we weren't here, whether it's vacation or camp or taking a trip we would normally take," she said.

The first lady particularly values her family's annual vacations to Hawaii for giving the first daughters the chance to be with other young people outside of the White House.

"They can run on the beach and be away and be normal. That's so important and I fight for that for them," she added.

The Obamas spent this past Christmas vacationing in Hawaii, a state where the president grew up and has visited every year for the holidays since his election.

Mrs. Obama praised her daughters and said they have handled the pressure of the presidency with "grace."

Despite saying her children "don't complain," Obama did admit that the girls occasionally get embarrassed by their famous parents. 

"For me it's singing and dancing," said Obama as she showed off her moves. "When we're at a place somewhere and I want to get Sasha to laugh, because I think she's focused too serious it's like 'if you won't smile I'm going to start dancing. She's like 'no, don't dance,'" Obama said.

As for the president's embarrassing behavior: just showing up at school is enough to make his daughters cringe.

"They don't really want us to come up to school, especially the president, because when he comes for parent-teacher conference it's like a motorcade. And the other day Malia was like 'Oh, no. Is dad coming? Is he bringing all those cars?'" she joked.
