In the first photo of the 33-year-old Homeland star with her little one, Danes holds her one-month-old tyke close, palming his head as she makes her way through security.
The new mom, who took home a Golden Globe for Best Actress in a TV Drama Series, told E! News before the awards show that her son has a "very calming presence."
Danes went on to say motherhood is "great," adding, "I'm seriously happy—and also sort of startled to be in this scene suddenly, I've been so sequestered, I've been in baby world."
The actress and her husband, who tied the knot in September 2009, welcomed their son Dec. 17.
