Sophie Elizabeth made her Sunday debut in the world in dramatic fashion, arriving in the back of an ambulance on Wantagh Parkway with the help of a trio of Nassau cops and a medic.

In an interview Monday night from their hospital room at Nassau University Medical Center in East Meadow, mom Stephanie, 38, and dad Kevin, 37, both of Wantagh, recounted Sophie's eventful birth.

Sophie, who is healthy and weighed 8.8 pounds at birth, slept in her mother's arms as she was cooed over by the uniformed cops who helped with the delivery.

"She's perfect," said Stephanie, who also has a 4 1/2-year-old daughter, Emma. "She's perfectly healthy."

The married parents, who declined to provide their last name, were at home early Sunday when Stephanie's water broke. Kevin called 911.

"It was a little frightening to say the least," he said.

Police soon arrived at the home and quickly got mom in an ambulance by 4:10 a.m. Dad followed in his own car with a neighbor driving.

"I was scared, but this baby was coming," Stephanie said.

Police medic Thomas Mastakouris, who doubles as a fire commissioner in South Farmingdale, relaxed her, she said.

"He was just very calming," she said. "As soon as he entered the house, he was just like, 'OK, the gloves are on, we're going to do this.' I didn't even worry. I knew I was going to be fine."

Mastakouris rode in the back of the ambulance with rookie Seventh Precinct Officer Jon Steigele. By 4:12 a.m., Sophie was crying.

Seventh Precinct Officer Erik Diaz, a 7-year-veteran, drove the ambulance and Officer Michael Sherlock, a 30-year-veteran, escorted the ambulance and dad's vehicle.

The medic and the officers, who visited the family Monday night, all pitched in and got the baby -- and big sister Emma -- gifts from the Babies R Us in Massapequa.

"We were just doing our jobs," Sherlock said.
