The Hollywood couple, who raise Maddox, Pax, Zahara, Shiloh, Knox and Vivienne, often travel around for work purposes.
Speaking to OK magazine, Jolie revealed that Pitt creates imaginary games to take their minds off the pressures of relocating.
"Brad is very good at making sure the children never feel stressed when we're moving around," she said.
"He always makes them see it as a little game that we have to play, which in a way it is.
"But we also know we have a very interesting life together and we've just adapted to make things as easy as possible for the kids so they can grow up as happy as possible."
One report last week alleged that the couple, who announced their engagement in April, are planning to marry in the UK.
Angelina Jolie and Brad Pitt have been an item since 2006.
