One Rhode Island couple headed to Florida expecting to embark on a cruise vacation. Instead, they found themselves embarking on a journey of parenthood after the mom, who did not know she was pregnant, unexpectedly gave birth.

Key Takeaways:

• Gary Glenn and Lauren Siwinski were preparing to leave on a cruise when she unexpectedly went into labor. Siwinski hadn't known she was pregnant.

• Baby Sebastian was born at 33 weeks gestation.

• The couple was overwhelmed at first but are grateful for the support they have received from family and friends.

The Details:

Gary Glenn and Lauren Siwinski traveled to Florida in early July to embark on a Royal Caribbean cruise. The night before they were scheduled to leave, Siwinski started experiencing sharp stomach pains and decided to visit the emergency room. There, she was shocked to learn that she was 33 weeks pregnant and already in labor.

The engaged couple had no idea that Siwinski was pregnant, as she had reportedly been on birth control and had no symptoms or signs of pregnancy.

“He comes back, and he goes, ‘You guys are pregnant.’ And I’m like, ‘Is she – what?’ You feel like you’re pinching yourself, and you’re like ‘What are you talking about? This isn’t real,’” Glenn said.

Swiniski explained, "I felt some flutters. But I didn't think anything of it. I thought it was just my stomach settling from something I ate. Didn't think it was a human."

The couple's son, Sebastian, was born at HCA Florida Brandon Hospital a mere 12 hours after his parents learned they were expecting.

Zoom In:

After canceling the trip and unexpectedly becoming a new mom overnight, Siwinski said she initially felt a little overwhelmed. However, the couple has received tremendous support, as Siwinski's coworkers have gifted them clothes, a crib, and baby supplies. It's the kind of support that can make all the difference to new parents.

“I was like, ‘I don’t know what I’m going to do, how I’m going to afford this,’” Siwinski said. “But the more support we get, the better and better I feel.”

The Bottom Line:

In a social media post announcing the surprise birth, the hospital noted the beauty of little Sebastian's birth.

“Sometimes life has a way of changing every plan in the most beautiful way,” the hospital said. “This little boy may not have made it onto the cruise, but he’ll forever be the best vacation souvenir his parents could have ever brought home.”
