‘Okay, it’s done!’ Stranger floors parents, crochets their baby a hat mid-flight.

Jake and Kelly Levine were worried about flying with their 5-month-old daughter, Romey.

“Before the flight I was very anxious,” said Kelly Levine.

She’s a naturally nervous flier, she said, and she feared that that Romey might be fussy, which could irritate other passengers.

“You never know what the people around you are going to think, and if they’re going to be bothered by a baby,” Kelly Levine said, noting that this was Romey’s second flight. The first was the week prior, when the family — who lives in Hoboken, N.J. — left for vacation to Cabo San Lucas, Mexico.
