Actress Angelina Jolie is happy to take a step back from acting to focus on her family, but admits she is lacking in sleep.

The `By the Sea` star is happy to have taken more of a step back from acting in order to raise her six children with partner Brad Pitt and says the only thing missing from her life is a good rest, reports femalefirst.co.uk.

"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.

Brad still enjoys acting as much as he always has, and I'm fully supportive of him.

"Acting is just not as important in my life as it once was and I'm very happy to be able to spend most of my time looking after our children.

"I don't feel as if I'm depriving myself of anything - except maybe sleep,` she said.

As her kids, Maddox, 14, Pax, 11, Zahara, 10, Shiloh, nine, and seven-year-old twins Knox and Vivienne, get older, Jolie is fascinated watching them growing and changing, and tries to spend as much quality time with them as possible.

She told Britain's OK! magazine: "It keeps getting more interesting watching them grow up and develop their personalities.`

"They ask more and more questions and have such a great curiosity about life. It's so beautiful to be a part of that. It takes up a lot of your time to look after a big family but I try and spend time with all the children every day. Spending time alone with each of them is important too,` she added.
