Siobhan and Bryan Anderson expected to welcome their twin baby boys next Friday, but Siobhan's water broke at about 5:30 a.m. Saturday morning -- nearly a full week early, Bryan said.
Heeding their doctor's advice not to rush or panic, they took their time and got into the car at about 7 a.m.
Siobhan said she felt a big contraction, and suddenly felt the baby's head, a few minutes after they pulled onto Southern State Parkway. She told her husband he was going to have to deliver the twins right there on the side of the road.
"She kept screaming, 'The babies are coming,'" he said. "I was like, 'I think we have time to at least get to the hospital.'"
Siobhan told Bryan to pull over near Exit 30, where he called 911....
"They were helping her out of the car and into the stretcher and that's when Gavin was born," he said. "Born right there on Southern State Parkway...."
Once Siobhan delivered the first baby, EMTs got her in the ambulance. The plan was to drive to the nearest hospital in time for her second son to be delivered.
Meanwhile, Bryan got back in his car and followed the ambulance, calling his brother-in-law to himself calm down.
"You don't think at the time that this is the way they used to do it back in the day," he said, adding that seeing his wife go through a surprise birth without pain medications was "very scary."
But less than 10 minutes later, the ambulance pulled over on Wantagh State Parkway.
Confused, Bryan said he jumped out of the car. EMTs told him "baby number two" was coming, and let him in the back door of the ambulence.
At 7:46 a.m. Declan was born at 5 pounds, 15 ounces.
