"Everything glows in the dark!" shouts Katourna. She asks me to reattach her glow stick bracelet. I can barely hear her over the thumping electronic music in the club. People are wearing blinking green sunglasses. Some girls are dancing on tables.

Before today, Katourna didn't know what a black light was, and she certainly didn't expect it would make her Ariel costume glow green. Katourna is six years old, as are many of the children at this nightclub. Instead of cocktails, they're balancing cupcakes. Rather than bottle service, it's literal bottles of milk.

Halloween Extravaganza is a "cool kid's dance party" for six- to 12-year-olds, presented by CirKiz. We're at a nightclub called VIP Room, in the Meatpacking District of New York City. Only it's a Sunday afternoon, and enough time has passed that the fumes and pheromones of last night's 21+ crowd have dissipated.

Event organizers and founders of CirKiz, Jenny Song and Jesse Sprague, are spouses and have kids of their own, six- and eight-year-old boys.

Song and I retreat near the street entrance to talk, since we can't hear each other over the thundering music inside. She is wearing a rainbow neon tutu, hot pink hair extensions and matching day-glo lipstick. It's your standard electronic dance music (EDM) uniform.

I ask her whether parents are comfortable bringing their kids to a rave. The parties are typically associated with all-night MDMA-fueled dance orgies (imagine a Miley Cyrus music video).

"For the kids, it's not about that," she says. "All the lights and colors are good for sensory, good for their eyes." And once the parents come, they "realize what wholesome family fun it is."

Song and her husband, who have been in the club business for 20 years, got the idea when they threw their oldest son's first birthday party at Cielo, another popular nightclub a block away. Parents loved it, she says, and urged them to plan more events where parents and kids could safely party together.

"A grown-up party would be more sophisticated," a fairy princess named Adriana, 11, explains to me. But she does like all the colors.

Today an instructor named DJ Natalie, founder of Baby DJ School, teaches kids about music pitches alongside some roaring house beats — it's like disco Hokey Pokey. Then a dance troupe of middle schoolers clears the floor and high-kicks to Ariana Grande's "Break Free." The youngsters are in awe. Parents look on, smiling between sips of Corona.

I ask Tristan, also six and dressed as Rocket from Guardians of the Galaxy, how a grown-up party might differ than this one. He responds, "More drinking."

His mother gasps in surprise, a wince of concern on her face.

Smart kid.
