Ben McKenzie and Morena Baccarin are “finally sleeping” six months after welcoming daughter Frances Laiz, and it’s thanks to one special person: their night nurse!

The star and Baccarin — whose romance was revealed in September of last year — welcomed Frances in March. Baccarin is already a mom to Julius, 2½, with ex-husband Austin Chick.

And Baccarin is totally proud of McKenzie’s daddy skills, telling PEOPLE earlier this year, “Ben’s the sweetest.”
