Sienna Miller had her daughter, Marlowe, in 2012 with her then-fiancé, Tom Sturridge. For Miller, having a child "changed everything." "The stakes are higher," she explained to The Guardian. "You have someone that you want to be proud of you eventually." She also reached a new sense of mortality. "For me, as soon as I had a baby I had a vision of my life — and what was left of it," she said.
Things changed, on a practical level, too. In her career, she began focusing on theater work or smaller film roles that she could film quickly. "I've done a play, which you can kind of get away with because you have the days off, but the idea of three months on set in every scene is really daunting," she told The Talks. She explained that she was still working on getting the balance right with her job so that she had enough time with her daughter. She even found herself caring less about landing big parts. "To get that balance right, to fulfill your creative needs and also be there for your kids," she explained. "So, I do find that now I'm a parent, my ambition has, to a certain degree, dwindled."
