Ashton Kutcher is basking in the glow of fatherhood, having welcomed daughter Wyatt Isabelle with fiancee Mila Kunis just 10 weeks ago.

Kutcher sat down with Ellen DeGeneres for an episode airing Friday and gushed about raising a child with Kunis.

“The most amazing thing about having a baby is my partner, Mila,” he said. “She’s the greatest mom. I go to work everyday and I come home, and she’s perfect, and it just seems like everything went amazing. And I know that something probably didn’t go amazing but she never complains. It’s unbelievable. She’s incredible. I’m really lucky.”

Kunis, 31, gave birth to their baby girl on Sept. 30. This is the first child for the engaged pair and Kutcher said they’ve decided not to hire a nanny.

“We just want to know our kid,” he explained. “We want to be the people that know what to do when the baby’s crying to make the baby not cry anymore. We want to know, like, when she makes a little face or a little something, we want to be emotionally in touch with her. And I think the only way to do that is by being the one who’s there. And that’s it.”

Earlier this week on “The Late Late Show,” Kunis talked about getting to be a stay-at-home mom (for now) with host Craig Ferguson, calling it a “luxury” and a “blessing.”

As for the “Two and a Half Men” star, he said becoming a dad is the “greatest opportunity of my life.” He referenced a quote by businessman and philanthropist Carlos Slim, who said: “Many people want to leave a better world for their children. I’m trying to leave better children for my world.”
