Maturity Over Conflict

Miller highlighted the mental shift that comes with a decade of self-discovery. While her 20s were marked by a feeling of being "scattered" and wanting to be everywhere at once, her 40s have brought a newfound appreciation for stillness.

"If I’m in bed at 9 p.m. with a book, I’m so happy now. Life is in a more grounded space. I think the 30s are chaos... by the time you hit 40, you’re like, 'I kind of know who I am.'" — Sienna Miller to Glamour.

The "Existential Relief" of Egg Freezing

Though Miller conceived her third baby naturally, she revealed that she froze her eggs in her late 30s. While she didn't end up needing them, she described the act as providing "existential relief," removing the biological pressure that many women feel as they approach 40.
