Sienna Miller recently offered a glimpse into her summer on Instagram, sharing a series of photos that included her newborn son and model Cara Delevingne. Miller, 44, posted an image of her baby boy, her third child and second with fiancé Oli Green, being held by Delevingne, 34. The infant's name has not been publicly disclosed.
Delevingne responded to the post with heart emojis, while singer Rita Ora commented, "I miss you." The photo collection also featured Miller with Green, 29, who recently proposed shortly after welcoming their second child together. One image shows Miller and Green posing in a mirror selfie, with Miller wearing a crochet dress, straw hat, and sunglasses.
Another clip shared by the actress shows Green pushing their baby's pram and smiling. Miller also documented moments of relaxation, including receiving a massage and getting her hair done while wearing a face mask.
In a previous interview, Miller spoke about her surprise pregnancies in her 40s, expressing a long-held desire for another child that she had begun to make peace with not happening. "I'd wanted another baby for so long that my postpartum was just bliss," she told Vogue. "I had thought, by the time I was 40, that it wouldn't happen. That I'd have my one baby and I kind of made peace with it. It was such a surprise, and it was such a bonus that I was just euphoric. I felt existentially relieved."
She also reflected on the challenges of first-time motherhood with her elder daughter, Marlowe, 14, noting that there was less focus on postpartum care at the time. Miller experienced a difficult postpartum period after Marlowe's birth, which involved an emergency C-section, leading her to feel "disappointed" and like she had "failed."
For her third child, born in May, Miller planned for a natural birth after two previous C-sections, a feat she described as "unheard of." She enlisted the help of Dr. Gowri Motha and the Gentle Birth Method, a program combining self-hypnosis, visualization, and Ayurvedic teachings. Despite the natural birth and subsequent care, Miller expressed regret about returning to work too soon, appearing on The Tonight Show Starring Jimmy Fallon just five weeks after giving birth. "It was all too much," she stated. "I thought I could manage it, but it was just complicated and hard."
Miller announced the arrival of her third child in May with a simple message: "It's happened. I have a tiny baby next door." She had revealed her pregnancy in December, showcasing her baby bump at the Fashion Awards.
