Another “Below Deck” baby has arrived.
Kate Chastain’s son made his adorable Instagram debut on Friday.
“Hard Launch: Sullivan Cay 💙,” the 40-year-old captioned a hospital selfie with the newborn.
The social media upload came five months after Chastain announced her pregnancy, keeping quiet about the little one’s paternity.
“I’m already planning so many birthday theme parties for you 💗💙💗💙,” she captioned her December 2022 baby bump debut in a cutout floral dress.
Fellow reality stars Dani Soares and Alli Dore, who have children of their own, celebrated in the comments section at the time.
“Aww congratulations 🎊 ❤️❤️,” Soares gushed, while Dore predicted Chastain would make an “amazing mum.”
The Bravo personality shared her May due date with People, saying she couldn’t hide her budding belly “any longer.”

She added, “I am absolutely thrilled to become a mother. It’s something I’ve always hoped for so this is truly a dream come true!”
While Chastain currently stars on “Below Deck Galley Talk” and “Bravo’s Chat Room,” she is best known for her role as chief stewardess on Seasons 2 through 7 of “Below Deck.”
The party planner’s relationships with chef Ben Robinson and former professional soccer player Ro Hernandez played out on the show.
It is unclear whether Chastain is currently dating anyone.
However, she did clarify on “Watch What Happens Live” in December 2022 that she plans to raise her child “solo and perhaps with some help.”
She noted, “I’m happy to do it alone. I think being a chief stew really trained me for it.”
Although her former co-star Lee Rosbach does not “do diapers,” the captain told People that he plans to “do a lot of [other] things” to support Chastain in her new role.
“Somebody on Twitter the other day [called me] Captain Grandpa,’ which I thought was a sweet thing,” he gushed.
