How Obama's kids got him to stop smoking

As the president tried to quit, the first lady said there wasn't too much discussion at home. "When I knew that he was trying, we just didn't talk about it," she told me, saying she avoided adding additional pressure with questions such as, "How are you doing today? Is it hard? Did you smoke?"

"And it was probably a year out that he was able to talk to the girls and say, ' I've quit' — or he felt comfortable saying, 'Dad quit," she added. "But it wasn't something that they were asking him about every day because they never really have seen him smoke. He's never smoked around them so it wasn't part of their daily lives."

Mrs. Obama said smoking is just one of many topics she and her husband talk openly about with the girls.  "We talk about drugs, we talk about sex, we talk about smoking, we talk about it all," Mrs. Obama told me. When I asked if she's had "the talk," she said, "We've had all the talks there are to have. I mean Malia is very inquisitive and open, and our view is that you've got to approach kids where they are, and when they ask a question, our reaction and how open and how comfortable we are with the topic really affects their willingness to share."

Come back for tomorrow's video when the first lady reveals something she's never talked about publicly before — and it concerns getting the kids, when they're young, to sleep — something every parent can relate to.
