Nicole Kidman loves playing with her kids because it ''brings back the child'' in her.

The 48-year-old actress cherishes the time she spends with seven-year-old Sunday and four-year-old Faith - her daughters with husband Keith Urban - and thinks it is important to ''get down on the floor'' to play the games they like.

Asked how she spends her free time, she said: ''With an hour free, it depends. I love getting down on the floor and playing with my kids. I read an article that says it's so important to actually get down on their level and play with them for an hour a day. So I do that, and I love that. It brings back the child in me.''

When she is able to snatch brief moments alone, Nicole - who also has kids Isabella, 22, and Connor, 20, with ex-husband Tom Cruise - likes to meditate.

She told DuJour magazine: ''With one minute, I'll daydream or meditate. I love just sitting quietly meditating.''

But the ideal day for the 'Grace of Monaco' star would involve a ''long, leisurely breakfast'' and time on the beach.

She said: ''I love breakfast; it's my favourite meal. So a long leisurely breakfast is just beautiful to me. I'd read the papers and go for a swim.

''If I was in Sydney, I love the beach. Even though I'm incredibly pale, I put on these terribly long unattractive rashies, and people laugh at me. My kids laugh at me. But that's what I would do.''
