“We are feeling happy but a bit nervous as well. It’s a new member of the family,” says the couple. (They also share daughter Naiella, who celebrated her third birthday earlier this month.)

“While it will shift focus for us again, our daughter will probably be affected the most, so we are making sure she feels comfortable and excited with the change to our growing family,” they add.

In April, Colter opened up to PEOPLE’s Celeb Parents Get Real about his little girl, revealing that she’s quickly learning how to communicate with him to get what she wants.

“I thought I’d be more strict, but I think it’s a combination of strict and fun because if I tell her to do something, she takes her time. She looks at me and sizes it up, deciding whether she’s going to do it or not,” said the actor, 41.

“She says no, but I can tell she’s trying to calculate how much she can get away with,” he explained. “I’m pretty firm because if she doesn’t listen, I say, ‘You have to be a good listener,’ and if she doesn’t listen then I get pretty serious with her and give her a talking to. I let her understand that there are ramifications for not listening to Daddy.”

And the couple’s daughter is also speaking her mind — adorably, of course. “She doesn’t understand that some things are weird, like you don’t say certain things,” Colter recalled.
