Nicole Kidman is finding it harder to work now her daughter is getting older.

The Oscar-winning actress doesn't want to disrupt 17-month-old Sunday Rose's schedule too much so has turned down roles so they can remain in their Nashville home.

Nicole - who is married to country singer Keith Urban - said: "I just can never be away from her, so she comes wherever I go, as you see. Have baby, will travel. She's OK on planes, but honestly, we stay in Nashville a lot. That's why I don't work that much. It's harder now to pack to her up. At 17 months, it's a different type of travelling. When they're six weeks, they're easier to travel with. And you're breast-feeding, so it's easy to feed."

However, Nicole did sign up to star in new musical movie 'Nine' shortly after Sunday's birth and says she has her daughter to thank for the curves she shows off in the film.

She told the USA Today newspaper: "I was wrapped into that dress. I was! That's when I had big boobs from the milk! That's the benefit of the breast-feeding."
