More than 100 parents and  their kids packed City Hall Park on Sunday to rally against Mayor Eric Adams’ mask mandate for children ages 4 and younger  — demanding the city “unmask our toddlers.”

The protest was the just latest example of the vehement pushback from Big Apple parents who want City Hall to do away with the regulation on youngsters, given  local plummeting COVID-19 rates and high vaccination levels among the much more vulnerable older set.

 “[The mandate] is not following the science. This is making a mockery of the science. This is playing us for fools,’’ said rally-goer Daniela Jampel, a 38-year-old mother of three, including a 4-year-old in public pre-K, from Washington Heights.

“New York state recognizes the science. Everywhere else in New York state — 10 miles away in Nassau County, 10 miles away in Westchester County — toddlers are allowed to take off their masks along with their older brothers and sisters,’’ she said.

But  “our mayor and our new health commissioner tell us it’s not safe for toddlers to take off their masks,” Jampel told The Post at the rally.

Earlier this month, Gov. Kathy Hochul rescinded mask mandates for everyone, although she left it up to the state’s counties to continue to enforce the requirement if they wanted.

New York City ended up lifting its school mask mandate a week later but  not for its youngest population, even though the  mortality rate for the group is the lowest of any age.

Kids under age five  aren’t  yet eligible for vaccines.

Adams and his new health czar, Dr. Ashwin Vasan, only added fuel to the fire recently when they appeared to be at odds over how long the city’s kiddie face-covering mandate would last.

Sunday’s irate parents held aloft signs reading, “My kid, my choice,” and “Follow the science” during the protest.

Adams has already  lifted the city’s Key2NYC vaccine mandate for restaurants and other indoor venues — a move that critics point to as inconsistent with the toddler mask mandate.

According to statistics collected by the American Academy of Pediatrics, only between 0.1 percent and 1.5 percent of children who are infected with COVID-19  have to be hospitalized — and 0.01 percent or  less die from contracting the global pandemic.

“Why do the kids who carry the least burden and the least amount of hospitalization in this country, in New York City, have to be masked, when the mayor just dropped the mandate for vaccinations at public restaurants, movie theaters, for elderly, unvaccinated, morbidly obese, cancer patients who are going to put a huge burden on the health system if they get COVID?” argued Dr. Dyan Hes, a pediatrician and medical director at Gramercy Pediatrics, at Sunday’s protest.

“But these little children, who put the least burden on the health system and have the least risk, are still forced to mask?”

Eric Olson, 45, of Park Slope, Brooklyn, who has a 3-year-old son James, called on Adams to provide a timeline for when the tots can forgo masks.

“How long is this going to last? We want a timetable from the mayor on when this is going to end, and he hasn’t given us any information that we know of,” Olson said.

The debate over the mask mandate comes as a new Omicron subvariant known as BA.2 has been surging — a less severe strain of the virus that is nonetheless more easily transmitted, medical experts contend.

Confronted by an irate parent earlier this month, Adams assured that the toddler mandate would not be around for long, telling the concerned dad that the children  would “be unmasked.”

“I got this. I’ll take care of this,” the mayor said. “They’ll be unmasked.”

The comment seemed to be at odds with statements made last week by Vasan, who said that the mask mandates for children should remain “indefinitely.”

“I think it’s indefinite at this point,” Vasan said Friday. “People who have tried to predict the future in this pandemic have had egg on their face, and I’m not going to do that today.”

Citing his own toddler, the commissioner said he wants to keep Big Apple youngsters “as safe as possible.”

“I would love nothing more than to send my son to daycare without a mask,” Vasan said. “But as scientist  and as a doctor and an epidemiologist, I want to keep him safe.”

Following Adams’ statements to the contrary, a City Hall rep sought to “clarify” the seeming disagreement between the two.

“There is no difference in their positions on masks or vaccine mandates,” spokeswoman Kate Smart said Saturday.

“The commissioner was explaining why children should remain masked currently, but they both look forward to lifting the mask requirements when it is safe to do so,” Smart said, “and we expect to share an update very soon.”
