Kathryn Hahn added summer blockbuster to her resume when she starred in the hit comedy Bad Moms, and now she says she’s dealing with another bad thing: her daughter’s language.

Hahn, 43, shared that Mae, 7, her daughter with husband Ethan Sandler, 43, just hit a milestone every parent dreads: swearing.

“Oh my God. My daughter said her first proper swear word. That was a milestone in our house,” Hahn told PEOPLE at the Alliance of Moms Presents Raising Baby event in Los Angeles on Saturday.

“It was not a good one, but it was used correctly,” she says. “It was used as an adverb and there was a big old ‘ing’ on the end.”

While it might not be the ideal choice of language for any parent, Hahn chose to see the silver lining in the situation.

“Okay, alright, at least it’s grammatically correct,” she jokes

When Mae isn’t expanding her vocabulary, she spends time reading with her mom, one of many “like mother, like daughter” moments Hahn has experienced with her little girl.

“We’re reading Charlotte’s Web for the umpteenth time,” she says. “Amelia Bedelia — I’m so excited that I can now read it to them.”

Her son Leonard, 9, has a different taste in literature.

“My son is big into Harry Potter, big into Mad Magazine at our house, which makes me laugh,” Hahn says.

Now that her children are older, Hahn says there’s no fooling them anymore.

“They’re starting to read to me,” she says, noting that her daughter has caught on to some of her mom’s shortcuts. “I used to edit … like, it’s too long and boring. I’m just going to cut out these chapters, and now she’ll call me out on it, so it’s not as fun.”
