A baby’s visit to Rikers Island took a frightening turn last week when the child started choking on a chip — prompting the city’s Boldest to leap into action to save him.

The 1-year-old began turning blue after swallowing a Dorito around 7:40 p.m. Sunday in one of the jail’s visitation areas, where his mom, Savanah Webb, had just finished seeing an inmate.

One correction officer noticed little Demyri Webb struggling.

“I was standing behind the desk and I noticed the baby bent over trying to cry,” said Aisha Stanislaus, a 14-year Corrections Department veteran. “The baby was turning blue.”

She tried the Heimlich maneuver, but it didn’t work.

That’s when Correction Officer Santos Barbosa Jr. heard an alert come over his radio and sprung into action. When he arrived in the visiting area, he saw people huddled around the child, including the panicked mother.

“She was yelling hysterically that her baby couldn’t breathe,” Barbosa, 41, told The Post. 

Barbosa, a corrections officer for 18 years who’s worked previously at a private ambulance company for three years, began doing CPR compressions to the baby’s back.

But the life-saving technique wasn’t working.

So he put gloves on and “performed a finger sweep” to try to dislodge the chip, to no avail.

The pressure mounted as Demyri struggled.

“At this moment, I asked my partner to open the front door so the baby and I could get air,” Barbosa recalled. “Everyone’s emotions are running high. Once the door is open, I go outside and perform another set of compressions.”

The baby’s abdomen was getting distended, he said.

“I could tell that in a few more minutes if the baby’s not breathing the situation is going to be worse,” he said.

So he pushed his pinky down into the child’s throat even farther — until he felt the chip move.

“The baby started to wheeze, which told me air was moving in and out,” he said.

Then Demyri spit up, and Barbosa knew the child was in the clear.

He performed a final set of compressions to be sure and “the baby started crying,” he said.

Barbosa told the mom to give her baby a bottle, and the tot was taken to the hospital.

“I really don’t get nervous or emotional, but I’m a little teary-eyed,” Barbosa said as he retold the story.

In addition to Stanislaus and Barbosa, Correction Officer Anouk McQueen, who has been on the job 17 years, stayed with Demyri until an ambulance arrived. 

“This is my first for something like this,” she said. “I’m happy the baby’s alive.”

The officers deserve the recognition, said Correction Officers’ Benevolent Association President Benny Boscio.

“Correction Officer Barbosa’s quick thinking and life-saving efforts to save the life of a 1-year-old baby, who was choking and in medical distress, embodies the very best qualities of our essential work force,” he said.

Corrections Commissioner Lynelle Maginley-Liddie said the three officers “are shining examples of what it means to be a DOC hero.”

The baby was back laughing and singing a few days later, the thankful mom told The Post.

“He’s always happy,” she said. “He sings. He’s perfect.

“I was very grateful,” the 24-year-old said. “They were very good, fast, and got the situation under control.”
