Kathryn Dennis says that "time flies" when it comes to her two kids.

Speaking with PEOPLE at BravoCon in New York City over the weekend, the Southern Charm star shares that her two children — son Saint Julien, 6, and daughter Kensington Calhoun, 8 — are "growing up so fast."

"Time flies," the proud mom says, adding, "they're great."

Asked about co-parenting with ex-boyfriend and fellow reality star Thomas Ravenel, Dennis, 31, says she's "just focusing on building a better life for me, for them and our family."

"I have a great relationship with my kids," she adds. "We have a lot of fun."

During the Southern Charm panel on Sunday, Dennis made clear her sustained acrimony toward her ex, against whom she's battled for custody and traded allegations.

When a fan asked what advice the show's stars would give to themselves going into season 1, Dennis answered, "Pick a different guy."

Earlier this summer, Dennis shared a photo showing her wearing coordinated pink outfits with her kids as the family trio posed and laughed outside a big pink stone home.

"Be present in the moment," she captioned the set of three photos, which also included a close-up of Kensington in a leopard print "Queen" fleece. "Life is much shorter than we think."

On Mother's Day, Dennis celebrated her kids for making her a mom.

"Yes I gave you life but really you gave me mine," she reflected in the caption of a selfie with Saint and Kensie.

"Happy Mother's Day to us all 🌷especially you in heaven, Mom🦋," she added, referencing her mom Allison Calhoun Dennis, who died in August 2019.
