"We're really privileged that we have time and can afford to take time. We don't have a nanny or a night nurse or anything. It's just the two of us," Kutcher said.

"It's unbelievable. It's the greatest thing on earth. As soon as this child was born I immediately wanted to call my parents and just apologize because I never knew how much they loved me," he continued.

Their baby daughter, Wyatt Isabelle, was born Oct. 1.

Kutcher said that he has already learned the things that will calm down his baby, making him feel that he like a "baby whisperer now."

The "Two and a Half Men" actor also shared with Conan how he and Kunis agreed on  the baby's name.

"We had another name. We had it picked out and we're like, 'All right, this is the name.' Then we got pregnant a week - a couple weeks after we picked the name. But then when we were pregnant, the name just didn't fit the energy that we were feeling," he said.

"We were calling it the baby, but never by the name that we had given it. One night Mila was just like, 'This is not the name.' I'm like, 'okay it's not the name.' I had to get the creative juices going."

"We were going to a Lakers game and I've got name Tourette's. I just started listing off anything and everything that I saw," the funny man said.

"I was like, 'Sign! Truck! Wall! Door!' She's like, 'Shut up!' I'm like, 'If you don't accept my bad ideas, you'll never accept the good ones.' Then I was like, 'All right I've got a really dumb idea. What about Wyatt?' She goes, 'That's it.' I was like, 'Really? I did it?' She was like, 'Yeah, that's it.'"

The couple agreed to give her the middle name Isabelle "after Mila's grandfather ... so it has a little heritage."
