A pregnant woman heading to the hospital collapsed on an Upper East Side street — then gave birth smack in the middle of a crosswalk.
Polly McCourt, 39, went into labor at around 4 p.m. on Monday then tried to hail a taxi to the hospital near her home on East 68th Street and Third Avenue — until her baby decided she had other plans: To come out immediately.
A young doctor spotted the commotion and rushed to her side as other bystanders propped her up and covered her with coats.
“It was a crazy experience,” the baby’s father Cian McCorty, 40, told The Post.
“My wife was really calm very together….She’s a strong woman,” he said.
A crowd of roughly 50 onlookers formed and an ambulance arrived in minutes — but not before McCourt gave birth, while laying on the pavement, in less than five minutes, witnesses said.
Her doorman, Anton Rudovic — who had been helping her to the cab — said the baby simply couldn’t wait.
“Everything seemed normal, and then out of nowhere she screamed, ‘Stop, stop!’” said Anton Rudovic, her doorman who had been helping her find a cab.
“I asked her what was wrong. She said, ‘I’m having the baby! I’m having the baby right now! It happened so quickly, just like 1,2,3!,” Rudovic said.
“I’m overjoyed for the birth of my little girl. It’s been quite emotional,” said the baby’s father Cian McCorty, 40.
The couple named the baby Ila Isabelle McCourt after a good Samaritan named Isabelle, who helped deliver the baby, Cian said.
He hopes to eventually track down Isabelle, who left a gray coat at the scene, he said.
Neighbors and witnesses, some of whom caught a glimpse of the baby on her way out , called the experience strange and surreal.
“Having a baby in a hospital is a miracle. I don’t know what to call it when you have a baby in the street. It’s incredible,” Rudovic said.
He added, “[McCourt] said to me yesterday, ‘All my babies come out so fast. They just pop right out. I can’t believe it.’”
McCourt, a mother of three, was in good condition on Tuesday, family members said.
She declined, through family, to comment, saying she was simply too tired.
“It was quick —she popped that baby out in less than five minutes,” Angela Ciao, another witness, said.
