(nyt) Consider the perils of parenting in the White House. There is a movie theater, a bowling alley, a horseshoe pit, a swimming pool, five full-time chefs and dozens of household staff members ready to dish up ice cream at all hours. There are trips to foreign lands, dinners with kings and celebrities, swarming paparazzi and blaring motorcades, all with the potential to transform sweet little children into bossy, self-important ones. (Or lonely, dysfunctional ones.) What are presidential parents to do? Lay down the law, according to the newest parental unit in the executive mansion. President Obama and his wife, Michelle, might not be in Chicago anymore, but they say the old rules still apply when it comes to their daughters, Malia, 10, and Sasha, 7. In the Obama White House, bedtime is still at 8 p.m. The girls still set their own alarm clocks and get themselves up for school in the morning. They make their own beds and clean their own rooms. And when the much-anticipated pet arrives, they will walk the dog and scoop its poop. “That was the first thing I said to some of the staff when I did my visit,” Mrs. Obama said in an interview with ABC News, describing her talks with White House employees. “Don’t make their beds. Make mine. Skip the kids. They have to learn these things.”
