Jennifer Garner and her middle child, Seraphina, hit the park together in Pacific Palisades, CA, on Saturday. It was a sweet mother-daughter outing for the duo, without Sera's older sister, Violet, younger brother, Samuel, or dad Ben Affleck. Jennifer secured solo time for Violet last weekend, though we've yet to see the Garner-Affleck's newest member, Samuel. Jennifer and Ben both have big projects coming up — she'll be promoting The Odd Life of Timothy Green, while he has Argo, the latest film he has directed and starred in, coming out this year. Ben also just joined Twitter to help spread the word about some of his charitable causes, as well as the Red Sox, of course.
