Mila Kunis and Ashton Kutcher welcomed daughter Wyatt last October and it’s clear that the couple are relishing the nesting phase.

I am proud to be a stay-at-home mom. I have no desire to be in front of the camera. I find her to be the most challenging job I've had,” the “Ted” actress admitted in a Reddit Q&A.

"It is the most life-changing experience you can have, in my opinion. EVERYTHING changed," said Kunis of giving birth to Wyatt. "The amount of love that you have, the type of love that you have, changes, the way you look at the world changes ... everything has changed, because of her. I want an ecofriendly car, I want to compost everything, because I want the world to be better for her. And you have the opportunity to make a really great child for the world. Or a really great human being."

Kunis who was born in the Ukraine revealed that she speaks Russian to Wyatt all the time and Kutcher is also taking Russian lessons.

The 31-year-old actress also opened up about playing World of Warcraft.

"I have not played WOW in probably 5 years! Yes, I used to play. I played a LOT. I was in a guild, I led raids, I was a pretty badass mage. I had multiple characters. I was a frostmage, I think, by the time I stopped playing? But no, I stopped playing when everyone started having children. I was level 70, I quit at level 70, before the expansion pack."
