Cuties Down Under!

Nicole Kidman, Keith Urban, and their adorable daughters--Sunday Rose, 3, and Faith Margaret, 14 months--caught a flight to L.A. from Kidman's hometown of Sydney, Australia Wednesday afternoon. While her mom held tight to little sister Faith, the pink-clad Sunday held both parents' hands as the family strolled through Sydney Airport.

In the past, the Rabbit Hole actress, 44 has spoken about the issues she faced starting a family later in life with Urban, also 44. Kidman--who has admitted to struggling with infertility--gave birth to Sunday in 2008, and welcomed Faith via a gestational carrier in December 2010. (The Moulin Rouge star also helped raise Connor and Bella Cruise, whom she adopted with ex-husband Tom Cruise).

"I'm in a state of absolute wonder, having all this in my life," Kidman has said of her experience with motherhood. "I never thought this was going to be me in my forties."
