A Bronx tow-truck driver gave a big boost yesterday to a stranded couple — he delivered their baby.

Antonio Paulino, 50, was driving in East Harlem yesterday afternoon when a man flagged him down.

“He said, ‘My wife is giving birth,’ ” Paulino said. But the Orthodox Jewish father-to-be said his religion forbade him from touching the baby or the mother.

“I reached in and took the baby out,” Paulino said.
