Sienna Miller shares first gorgeous photos of her newborn

by Bryony Jewell / 2 weeks ago

‘Adulting’ is the phrase Sienna Miller used to describe the newborn phase with her third child and we couldn’t agree more.

You adult harder than you ever have before when it comes to the first few weeks of parenting a newborn and Sienna gets it.

The actress kept her third pregnancy under wraps, surprising fans in May when she announced she had a ‘tiny baby’ in her house, but she’s now shared adorable photos of her young family.

The actress and her partner, Oli Green, who have not shared their baby’s gender, are also parents to a little girl, who was born in 2023, and Sienna is also mum to a 13-year-old daughter, Marlowe.

In the new photos shared on Wednesday, Sienna is seen sitting in bed while heavily pregnant and cradling her newborn in the hospital soon after giving birth.

Other snaps show Oli looking tearful as he holds his second child and strolling shirtless along a London street.

The couple’s toddler is also in two of the photos, standing with her back to the camera with her impressive head of curls on full display in one image and walking with Sienna in another.

Sienna simply captioned the photos ‘adulting’, with lots of people sending their love to the new mum-of-three.

Among those leaving comments was singer Paloma Faith, who said: ‘Don’t be silly, you are a teen mum like me! Round three here toooooo!’

Sienna revealed she’d become a mum for the third time in May while chatting with E! News.

‘It’s happened. I have a tiny baby next door,’ she told the outlet. ‘It feels like stringing sentences together is a bit challenging. I’m on very little sleep, but I’m madly in love with my baby.’

She then shared a first glimpse of the little one while getting ready to appear on The Tonight Show Starring Jimmy Fallon. Sienna was seen breastfeeding her baby in the clip, while Oli cuddled their little one.

Sienna and Oli went public with their romance in early 2022 when they were spotted together in New York City.

Their romance was then confirmed when they left the BAFTAs together and headed for British Vogue’s Fashion & Film afterparty.

Weeks later, the two made their red carpet debut as a couple for the Vanity Fair Oscars party and also attended Wimbledon together in July 2023.
