In March, the dance pro revealed that the couple, who are already parents to 3-year-old daughter Amalya, were expecting their second child together.

“We are very excited,” Trebunskaya, 36, told PEOPLE at the time. “We definitely wanted to have more children than just Amalya, and I think she’s ready to be a big sister, so the timing is just right.”

And according to the soon-to-be mom of two, Amalya seems ready to take on her new sibling role.

“She keeps talking about the real baby,” explained Trebunskaya. “Of course, she has baby dolls, but she’s like, ‘I want to hold a baby.’ And I said, ‘Well here’s your baby.’ She’s like, ‘No. I want a real baby.’ And I said, ‘Well, we have a long way, baby. We need to have it hatch. It’s not ready yet.’ ”
