Sienna Miller gave the first public look at her newborn baby on July 1, posting a photo dump on Instagram that included the infant for the first time. The baby arrived about two months before the post, and the name still has not been shared.
One image showed Oli Green tearing up while holding the swaddled newborn close to his chest. Another showed Miller cradling the baby against her chest, with a red heart emoji covering the child’s face.

The post matters because it moved the family update from a private arrival to a public image. Miller had already said in May that the baby had arrived, but the July 1 post is the first time she has shown the child’s face area at all, even with the emoji covering it.
That keeps the basic facts simple for readers tracking the family: Miller and Green now have a second baby together, and the new arrival makes Miller a mother of three. She is also the mother of a 2-year-old daughter with Green and Marlowe, 13, with Tom Sturridge.
May 14 and May
Miller had been talking openly about the adjustment before the photos arrived. On May 14, during an appearance on The Tonight Show Starring Jimmy Fallon, she said, "I would have said the teenage girl would be harder to juggle until the transatlantic flight I took yesterday with the toddler and the newborn" and added, "The toddler now wins hands down. It was an absolute disaster. There’s no negotiating."
In May, she told E! News, "It’s happened" and "I have a tiny baby next door." She also said while promoting Tom Clancy’s Jack Ryan: Ghost War, "It feels like stringing sentences together is a bit challenging" and "I’m on very little sleep but I’m madly in love with my baby."

The new images leave one practical question unanswered for readers following the family: what the newborn’s name is. Miller is sharing the baby publicly before sharing that detail, which means the photo update stops short of a full introduction.
For now, the July 1 post gives the clearest public marker of the baby’s arrival: a first look, a visible family unit, and no name attached to the face covered by the heart emoji.
