Sienna Miller, who recently welcomed her third child, got candid about her journey of motherhood.

The 44-year-old recently appeared on The Tonight Show Starring Jimmy Fallon, where she was asked whether being a mom to a teenager, a toddler, or a newborn was "harder to juggle."

For those unversed, Sienna welcomed their first daughter with boyfriend Oli Green in 2023. The 'Anatomy of a Scandal' actress also shares daughter Marlowe, 13, with ex Tom Sturridge.

“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. Sienna told host Jimmy Fallon.

She further said, "The toddler now wins hands down. It was an absolute disaster. There’s no negotiating."

“And then the looks people give you on the flight ... The baby’s screaming, she’s screaming. It was like, 'Yeah,'" she added. “I got to the immigration line and just broke down."

Sienna announced the birth of her third baby in an interview with E! News on May 11.

"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," added the American Sniper actress.
