Dr. Nicole Martin is introducing her baby girl to the world!

On Friday, the Real Housewives of Miami star, 39, posted a photo on her Instagram of her son Greyson, 4½, holding his newborn baby sister as the two snuggled up together. Greyson held out a thumbs up, placing one arm around his sister, who cuddled into his neck.

Martin also shared a sweet photo of her daughter resting in a car seat, sleeping under a pink blanket, and wearing a pink bow headband.

“Feeling all the feels 💕🙏🏻🥹 #Home #Friday,” Martin wrote in her caption.

Resharing the post on her Instagram Stories, Martin added, “All the Friday Feels 🥹 Thank you for all the warm wishes. The family is home.”

In March, Martin and her fiancé Anthony Lopez shared on her Instagram Stories that they’d welcomed their baby daughter a little earlier than previously expected.

“It has been hectic, to say the least, but Mommy and baby girl are recovering from a C-section that was earlier than expected but here we are,” Martin shared.

“We’re doing good. And thank you for all the warm wishes,” she continued. “But overall, we are doing well. I am feeling okay. A little nauseous but otherwise not too bad and baby girl is trying to figure things out.”

In November, the reality TV star exclusively revealed her pregnancy news to PEOPLE.

“Anthony and I wear many hats, but we always say that being parents is by far our favorite!” said Martin. “We have so much fun with Greyson and are over the moon about expanding our family.”

Martin also shared that her younger son was already looking forward to becoming an older sibling.

“Oh, he is very excited about the addition to our family,” the reality star raved. “He has been asking for a sibling for quite some time, and I know he’s going to be a wonderful big brother.”
