The adorable trio first dropped by a local park to work up an appetite on the playground equipment before proceeding on to grab up brunch at Jack n' Jills restaurant.
The Alba/Warren family excursion comes shortly after Jess spoke with press about her desire to give Honor a sibling.
"Honor is so beautiful and I feel so enriched by being part of her life. She's my main priority now and I want to give her the best life possible. Before she was born I was totally focused on my career, but now with Cash and our daughter I feel that I'm building a wonderful family. I would like to have more children at some point," Alba revealed.
The 29-year-old actress added, "We didn't plan on starting a family so soon but when it happened we realized what a beautiful moment it was. We're a lot closer. The beauty of marriage and having a family is knowing you're sharing everything with someone else and are committed to being part of each other's lives. Cash and I understand that and together with our daughter, we want to have a wonderful life."
