Yeh, 32, and Hagen are already parents to daughter Bernie, 2, who has been adorably preparing to be a big sister. “She’s sooo excited!” Yeh told PEOPLE earlier this year, before giving birth. “Every day she pats my belly to say good morning to the baby. She’s gotten great at changing diapers on her dolls, putting them down for naps, and reading books to them, so I’m pretty sure she’s going to want to raise this baby herself!”

“She’s also currently in a major Frozen phase so I think she’s going to lose her mind once she realizes that she has an Anna to her Elsa,” added Yeh.
