A Florida mother hit up a nightclub for over an hour as her toddler slept on a sidewalk and her two other kids were home alone, authorities said.

Shyla Heidelberg, 25, was arrested Saturday after one of her children — a 3-year-old — was discovered at 1 a.m. wrapped in a blanket while asleep on a sidewalk outside an apartment complex in Fort Walton Beach, according to the Okaloosa County Sheriff’s Office.

Responding deputies then found Heidelberg’s two other young children asleep and alone inside a unit at the Choctaw Village Apartments, where a security officer at the complex had initially spotted the 3-year-old outside, WKRG reported.

Heidelberg — who was busted when she returned home — admitted to investigators she had “gone out to a nightclub” about 90 minutes earlier and left her kids behind to fend for themselves, deputies said.

Heidelberg was charged with three counts of child neglect without great bodily harm. She was released from custody Sunday, jail records show. She denied the allegations when reached for comment early Monday.

“It wasn’t true,” she told The Post during a brief interview. “I have proof that I wasn’t in the club.”

Heidelberg said she has footage from her Ring doorbell camera that proves she didn’t leave her children to go to the club, as well as a few witnesses who will vouch for her whereabouts.

“A couple people can state that I wasn’t there,” Heidelberg insisted before hanging up.

It’s unclear if Heidelberg, of Fort Walton Beach, has hired an attorney.
