Mila Kunis speaks about daughter Wyatt for the first time: 'She moves!'

Though gorgeous Mila Kunis seems to be relishing her new role as mother to nine-week-old Wyatt, the new mom recently opened up for the first time about her plans for her baby girl - especially once the teenage years hit, at which time fiancé Ashton Kutcherwill be taking charge.

Speaking to comedian Craig Ferguson on The Late Late Show, her first interview since Wyatt's arrival, Mila told the Scottish-born host that she's well aware of the difficulties puberty brings and will be taking a back seat, thank you very much.

"That's not my problem. That's daddy's problem!" the first-time mum laughed.

"My sister-in-law had a little boy two weeks prior to us having our little girl and it is completely different. Everything," she added.

Mila, who looked incredible in a black mini dress that featured cut-out side panels, also credited her post-baby figure to breastfeeding.

The Black Swan star, who has previously revealed that she and Ashton do not have a nanny, seems to have her hands full as she quipped about baby Wyatt: "She's not lethargic. She moves!"

The family of three were most recently spotted enjoying an evening out together, when Mila, 31, and Ashton, 36, had an elaborate ten-course dinner at The Gadarene Swine in Los Angeles.

"They came in and did the chef's tasting," a fellow diner told People. "They came in and gave the chef a hug. They seemed to enjoy themselves. They were happy and laughing the whole time."

Mila and Ashton, who starred together in That '70s Show but didn't start dating until 2012, welcomed their baby girl on Sept. 30 at Cedars-Sinai Medical Center – a favourite with celebrities including Kim Kardashian and Jessica Simpson.

The couple named their first child Wyatt Isabelle, with Ashton revealing that he came up with her moniker after making suggestions to Mila.

"I just started listing off anything and everything I saw: 'sign, truck, wall, door,'" he said on Conan O'Brien's talk show. "She [was] like, 'Shut up!' I said, 'If you don't accept my bad ideas, you'll never accept the good ones.'

"Then I was like, 'I've got a really dumb idea. What about Wyatt?' She goes, 'That's it.'"

Ashton added: "We gave her the name Isabelle after Mila's grandfather, who was Yitzhak. And so it has a little heritage."
