'Nashville' Star Hayden Panettiere on How Her Body's Changed After Giving Birth

— -- Hayden Panettiere is over the moon after giving birth to her daughter, Kaya Evdokia, on Dec. 9.

But the "Nashville" star still says she is adjusting to how her body's changed after carrying a baby for nine months.

“I’m limping around. I’m still trying to figure out what [pregnancy] has done to my body, how it’s changed it," she told People magazine. "What’s temporary and what’s permanent. I feel like an 80-year-old woman trying to go down the stairs, you know, please tell me this is temporary."

She continued, "But I know some things will never be the same again."

The actress and her fiance Wladimir Klitschko have some help though. The boxer's mother has been relieving the new parents so they can get some rest.

Even so, Panettiere, 25, says her baby has an “insatiable appetite.”

"When they are putting you through the ringer you’re like, ‘You are so lucky you’re cute!'” she added.
