Peta Murgatroyd and Maksim Chmerkovskiy already had an amazing home waiting for baby Shai upon his arrival!

The Dancing With the Stars couple welcomed their son, Shai, on Jan. 4, and on Friday, Murgatroyd gave us an update on their newborn. The 30-year-old dancer also shared pictures of Shai's nursery, which was created by celebrity nursery designer Vanessa Antonelli.

"Shai has been doing all of the things a newborn should do," Murgatroyd tells ET. "Napping in his crib, snuggling with us and eating."

The new mom says the room was definitely influenced by 36-year-old Chmerkovskiy.

"Our house has a lot of cream and gold, therefore we wanted Shai's room to be an extension of this and feel royal and plush," she says. "Over the years, Maks has collected a huge range of elephant ornaments. We loved the idea of incorporating them in Shai's nursery for good luck, but only if the trunk was up."

Antonelli tells ET the couple's love of elephants stood out to her.

"Peta worked on the design directly with me and then her and Maks would talk things over to make the final decision," Antonelli shares. "Since they have no children or nieces and nephews, everything in the world of baby products is so new to them. They really relied on me to fuse what they wanted in design to what they needed in functionality. The three things that really stood out to me during our first meeting was that their metallic of choice was gold, they wanted the nursery to be very neutral and they like elephants."

And Antonelli is confident Shai is fond of his very first room!

"The day I went to Peta and Maks' home to shoot the images of the nursery, Peta was nine months pregnant and her belly was actually moving, everyone could see it bounce around," Antonelli recalls. "It was so adorable that the little guy was dancing in there already! You may think he simply has his parents' incredible dancing genes, but I think he really liked the nursery."

Early Friday morning, Chmerkovskiy Instagrammed for the first time since becoming a new dad, and he's already a protective papa.

"It's been one week plus one day of my fatherhood and I'm the happiest person that's ever lived," he wrote. "I'm also feeling very protective and now understand what every parent in history have been going through for as long as humans have been giving birth. I don't let too many people come see my son and I don't want to put any of him on social media just yet. @petamurgatroyd and I just want to enjoy our little family, together with our loved ones, and take in all the precious moments which we'll never get back."
