MILFORD, Mass. - Community EMS responders helped deliver a baby who's father also works with one of the paramedics as a Worcester firefighter.

“I was like, 'I think you need to call 911,'" Kayla Alvarez said. "And he was like, 'Are you sure?' And I was like, 'Yes, I think this baby's coming.'”

Alvarez said at 38 weeks pregnant, her daughter Mariah arrived earlier than expected.

“The night before, I was having pretty inconsistent contractions, like 10 to 15 minutes apart," Alvarez said. "Not my first rodeo, it's my second baby. So, I kind of knew birth was coming, but not right that night.”

At about 4 a.m. on January 29 at home in Milford, Alvarez woke up Mariah’s father, Prescott Caisey, and said it’s time to go.

“I told him, ‘I need to, you know, get ready because I think the baby's going to come,’" Alvarez said. "And as I got up to start getting ready, my contractions just hit me like a truck.”

Caisey, who’s a new Worcester firefighter, said he wasn’t expecting to see a familiar face at 4 a.m. EMT Kevin Carlucci and Paramedic Ruben Torres, who’s also a fulltime Worcester firefighter, answered the couple’s 911 call for Mariah.

“As soon as we were getting ready to go out of the apartment," Torres said. "Prescott ended up coming out of the back room and we automatically know each other from sight, from the academy at Worcester fire department.”

“Seeing him being one of the EMS providers that night," Caisey said. "I knew that she was in good hands. He had trained me in the fire academy, doing EMS and everything.”

Torres has more than 20 years of experience as a paramedic, which proved to be useful as Alvarez gave birth to Mariah minutes into their ride.

“Well, for Kevin, it was his first time. Me it was, this is my seventh one, but this is the first girl," Torres said. "We were on our way to UMass Memorial, usually where she would have given birth. However, the baby was excited to come into the world, and she came early.”

“In the ambulance, I kind of told Ruben I was like, ‘I think I need to push.’ And he looked, he said, ‘You're crowning.’ And he just looked at me, he was like, ‘whenever you're ready,’" Alvarez said. "And then I pushed and now baby Mariah's here.”

And now Mariah’s got a fun story about running into a familiar Worcester firefighter for the rest of her life.

“I could say I trust pretty much anyone in the fire department I work with my life if I really needed to," Caisey said. "So, you know, in that case in time, if he was there to give birth to her, I knew she was in good hands, you know, it would all work out right.”
