"I actually felt quite attached to the idea of having a girl, so when I found out it was a girl, I was ecstatic," Monet added. "It [also] made me feel some sense of, 'Okay, if this is it and we have two healthy, beautiful babies, I'll never wonder what it would be like to have a girl if I happened to have two boys.' So I feel very settled right now."

The Victorious alum also shared how she thinks Gio will be as a big brother: "amazing," of course!

"He's really loving, he's really affectionate," said the mom. "I think it'll be some adjustment — I already feel nervous about that, just because it happened all very quickly and I love my time with Gio and we're very much full-time parents. So I struggle when I think too much about it 'cause I'm thinking, 'Oh my gosh, my time with just him and I is [ending] so quickly.' So I'm just doing my best to be very present every day with him."

Hinting at potential names for their new girl back in October, Monet said, "With Gio, we knew right away and we knew that it had some sentimental feelings and family history, but [with] this one ... I think we'll go a different route."

On Instagram Feb. 7, Monet posted smiley sunset images of herself and Gardner, showing off her baby bump on what she predicted as their "final weekend before we add a new player."

"just want to say i feel really lucky to have this guy by my side," she wrote at the time. "we've had to have a lot of conversations lately about how we want to handle this transition for Gio, myself and as a family. they haven't all been easy, and without feelings, but we've come together in big ways and i'm proud of us."
