Kate Chastain and her baby dressed as Captain Lee

The 5-month-old, whom theBelow Deckalum welcomed in May, is set to appear on Monday night’s finale episode of Bravo’sCouch Talk with Captain Lee and Kate.

As seen in a preview clip of the episode posted onBravo’s Instagram page, Sullivan is fittingly dressed for the occasion in a tiny white captain’s uniform, complete with a bow tie in a nod to his mom’s co-host,Captain Lee Rosbach.

“Our very exciting guest is ready. He dressed up just for you,” Chastain, 40, tells her formerBelow Deckboss.

“And quite smartly, I might say,” Rosbach, 73, replies, before cooing to Sullivan as he nestled in Chastain’s lap: “So nice of you to be awake while I’m here.”

Chastain then jokingly explained the reason for his usual sleepiness: “He’s always been on anchor watch.”

When Rosbach asks if he can hold Sullivan, Chastain hesitates for a moment before lifting Sullivan up to do the smell test on his diaper. “Actually, yeah, he’s ready! He’s ready!” she says, laughingly implying it’s Rosbach’s turn on diaper duty.

Chastain — a yacht stewardess who starred alongside Rosbach on six seasons ofBelow Deckbefore exiting the show in February 2020—firstannounced her pregnancyin December.

“I am absolutely thrilled to become a mother,” she told PEOPLE at the time. “It’s something I’ve always hoped for so this is truly a dream come true!”

Back in January, while appearing onWatch What Happens Live, Chastain got emotional when she revealed that she wasn’t sure she’d get to experience motherhood. When hostAndy Cohenasked her if she “always wanted a kid,” she told him, “I did but I wasn’t sure if it was going to happen for me, so I just feel so lucky.”

OnWWHL’s aftershow, Chastain — who has not publicly revealed the identity of her son’s father — said she wasplanning to raise Sullivan on her own. “I’m doing it solo and perhaps with some help, but I’m happy to do it alone,” she told Cohen, 55.

After Sullivan made his grand arrival, Chastain shared the first photo of her son on Instagram. “Hard launch: Sullivan Cay,” she wrote, alongside a snapshot from her hospital room capturing her holding the newborn, who was swaddled in a striped blanket.

About two months later, she posted a lightheartedvideopoking fun at the realities of parenting an infant. “10 weeks later I think I’ve figured out how to get him to sleep,” she wrote, alongside footage of her rocking Sullivan in her arms as she paced all around her home in changing outfits as the days passed.

“It dropped below 90 degrees today so obviously we’re out celebrating the start of fall 🍂🍁,” she wrote in her caption.
