Gordon Ramsay and Tana Ramsay are settling in with baby No. 6.

The celebrity chef’s wife, who gave birth to their son Jesse James four weeks ago, posted a photo of the newborn to mark his first monthly milestone.

In the adorable shot, the baby boy looked cozy in a white onesie with little red, blue and gray stars sprinkled throughout, snuggled up in a blanket while looking straight into the camera.

“One month of this little one already, loving every minute,” Tana, 49, wrote on Instagram.

After the baby’s arrival, Gordon, 57, was the first to share the news, posting snaps of their newest Ramsay crew addition.

“What an amazing birthday present please welcome Jesse James Ramsay, 7lbs 10oz whopper,” the Kitchen Nightmares host captioned his Instagram gallery. “One more bundle of love to the Ramsay brigade!! 3 boys, 3 girls … Done 👊🏼❤️❤️.”

Gordon and Tana are also parents to daughter Megan, 25, twins Jack and Holly, 23, daughter Matilda “Tilly,” 22, and son Oscar James, 4½.

In September, Gordon spoke with PEOPLE about Tana wanting another child, saying they would have “another one” eventually. She had kept the pregnancy completely under wraps.

“I’m going to be at school celebrating sports day with a f—ing walker!” he joked. ” ‘Hey, who’s your granddad?’ ‘That’s my dad, actually.’ “

“So I’m not too sure how many knee hip replacements they’ll get by the time they get 21, but I’m going to try,” Gordon added.

“I’m one of four, Gordon’s one of four, so it’s sort of second nature to me,” Tana explained alongside her husband.

And while Gordon may be known for his bold on-camera personality, he said his wife is the stronger one out of the two.

“Tana’s super fierce, an ex-Montessori school teacher. So, I’m the softie,” he told people.

His wife added, “He is, believe it or not, incredibly sensitive — he’s a crier.”
