Alec, 64, is "a little bit" of a pushover when it comes to their kids around Christmas time, Hilaria, 38, shared with PEOPLE at the American Museum of Natural History's Annual Gala in New York City Thursday.
"I feel like I'm both good cop, bad cop," she added jokingly.
Like all busy moms, the yoga pro — who dazzled on the red carpet in a sparkly black Joy Cioci gown with dramatic cutout sides and silver heels — is also frantically preparing for the holiday season.
"Well, we have our stockings … and the elves — oh my God, the elves," teased Hilaria, who gave birth to 10-week-old daughter Ilaria Catalina Irena on Sept. 22. "I can't find the elves right now! It's actually a big emergency right now!"

This is particularly important when it comes to the couple's son Rafael Thomas, 7, who Hilaria said "has always been Mr. Christmas."
"He just loves it, it's just so magical," Hilaria continued about Rafael. "He thinks Santa's a superhero. He used to dress up like Santa. He just really loves Santa!"

"I think we want to go and see the [Rockefeller tree] lights," she said. "It was raining on the day that they lit up the tree — which we love, because Carmen lit up the tree one year when she was little and that was really nice."
As for 2023, Hilaria shared that she has a simple yet effective way to remain positive all year round: never make New Year's resolutions.
"You know what, I make resolutions when they come to me," she told PEOPLE. "Every day. 'You should try better with this, do better with this.' "
