"Gwen cradled him in her arms and was there while Zuma sat still for the photographer," an eyewitness tells OK!. "He isn't a fussy baby."

Gwen, 39, and Gavin, 43, who are also parents to 2-year-old Kingston, requested an expedited passport so they can travel to London over the holidays to visit Gavin's family. A pal of the couple tells OK!, "They can't wait for Zuma to see his first snow!"

Meanwhile, while photogs captured little Zuma at the library, Gwen and Gavin released an official photo of the tiny tot on Gwen's Web Site, choosing not to sell his photo to the press. The shot shows a natural-looking Stefani holding Zuma over her shoulder with a caption reading "We wanted to share with you the first photo of Zuma Nesta Rock Rossdale. Gwen, Gavin, Kingston and Zuma are all doing well and enjoying being a party of four."
