It was only a week ago that former Dancing With the Stars pro Anna Trebunskaya admitted she was in full nesting mode waiting for the arrival of her second child. She didn’t have to wait long, though — she and her boyfriend, Nevin Millan, welcomed a son over Labor Day weekend.

“Nevin and I would like to announce the birth of our beautiful, healthy baby boy, Kaspyan Millan,” Trebunskaya told Us Weekly in a statement. “He was born Saturday, September 2, 2017, over the Labor Day weekend at our home via water birth. Mama, baby, and family are all doing great. We couldn’t have asked for a more perfect birth experience. We are all so excited to get to know the new addition to our family and so grateful and blessed for this lovely gift!”

Kaspyan is a little brother to Trebunskaya and Millan’s three-year-old daughter, Amalya, who was so excited for her new sibling that she was “practicing” for his arrival in the weeks leading up to his birth.

“She keeps playing the family game, where I’m mama, she’s sister, and one of her dolls is a baby. I think it’s her way of ‘practicing,'” Trebunskaya told ET just last week. “It’s so adorable. We pretend to change diapers, [feed] baby bottles, and [put] baby to sleep. She’s so nurturing, so we’re hoping that carries over to her real baby brother.”

In an Instagram post about her new little one, Trebunskaya promised “photos and the story behind [Kaspyan]’s name” soon, so you know we’ll be keeping our eyes peeled for more adorable details. Congrats to the growing family!
