Michelle Obama and incoming first lady Melania Trump have spoken about the challenges of raising children in the White House.
Mrs Trump's 10-year-old son Barron Trump will become a teenager during President-elect Donald Trump's first term.
White House spokesman Josh Earnest said that is "a rather unique childhood".
He pointed out that Mrs Obama and President Barack Obama also had the experience of raising children in the White House.
Mrs Obama and Mrs Trump spoke about the experience of being a good parent under those unique circumstances, Mr Earnest said.
The two women then walked to the Oval Office to visit the president and the president-elect, he said.
