Hayden Panettiere has introduced newborn daughter Kaya to the world, along with some details about life post-baby.

The Nashville star and her fiance Wladimir Klitschko, 38, introduced daughter Kaya Evdokia in the Jan. 12 edition of People magazine.

“I’m limping around. I’m still trying to figure out what [pregnancy] has done to my body, how it’s changed it. What’s temporary and what’s permanent,” the actress told the magazine of the “surreal experience.”

“I feel like an 80-year-old woman trying to go down the stairs, you know — please tell me this is temporary! But I know some things will never be the same again,” she said.

Panettiere, 25, said she was “grateful” for her epidural and the help of Klitschko’s mother, who has been there to help out as they adjust to becoming new parents.

“She’s really so sweet,” Panettiere said of her new baby girl “I’m sure that’s the way it’s meant to be, because when they are putting you through the wringer you’re like, ‘You are so lucky you’re cute!'”
