The 37-year-old actress, who raises Maddox, 11, Pax, eight, Zahara, seven, Shiloh, six, and three-year-old twins Knox and Vivienne with fiance Brad Pitt, said she and Pitt enjoy family life very much, reported Contactmusic.
"It's just so easy for me to be looking after the kids even thought it takes a lot of energy and you don't have much time for yourself.
"The children are so much a part of my life and Brad's that we don't worry or stress ourselves about not working more often," she said.
However, the 'Maleficent' star said her large brood means she often feels sleep deprived, though that is changing now the kids are getting older.
"I don't feel as if I'm depriving myself from anything except maybe sleep. But now that the twins are older, Mommy and Daddy are getting a little more rest and time to be together."
