Katherine Heigl‘s two children are growing up fast — maybe even too fast.

The actress told PEOPLE at 2014 TrevorLIVE that her 2½-year-old daughter Adalaide has become quite the talkative toddler.

“[She] won’t stop talking,” Heigl, 36, said in Los Angeles on Sunday, adding that her youngest is learning to stand her ground.

“She goes, ‘No, no, no,’ ” the State of Affairs star says. “I know it’s so cliché, but I hear that word 100 times a day. It’s literally what is happening every day.”

Although her 6-year-old daughter skipped that phase, Heigl says Naleigh “started talking like gangbusters and hasn’t stopped talking for five years. Except to sleep at night.”

With the holidays right around the corner, Heigl and husband Josh Kelley plan to stay close to home before heading South to soak up some sun with their girls. “[We’re] keeping it chill and mellow in our homes in Utah,” Heigl says.

However, since the actress is a self-proclaimed “bad flier,” the family of four won’t be going far. “I try to go the least farthest possible,” she jokes of their upcoming getaway to Mexico.

TrevorLive is a yearly event put on by The Trevor Project, an organization that helps LGBT youth who are struggling with suicidal ideation.

But when it comes to her own girls — and her best friend, former Grey’s Anatomy actor T.R. Knight — Heigl says there’s not much to discuss.

“We don’t treat it like it’s anything to talk about. It just is,” she says. “I have gay friends … My best friend in the entire world is T.R. They come and spend the holidays with us. My daughters know it’s just Uncle T.R. and Uncle Patrick [Leahy].”
