Jennifer Garner and Ben Affleck Family Pictures

Today is Jennifer Garner's 40th birthday! We've already started the celebrating with a look at 40 happy photos of the big-smiled star, and now we're checking some of her and husband Ben Affleck's sweetest family snaps. The Garner-Afflecks became a group of five in February with the addition of their first son, Samuel Affleck. We have yet to see the little one but have rounded up some of the best images of Jen and Ben with daughters Seraphina and Violet as they enjoy visits to their local farmers market, shopping trips around LA, and hangouts at the park.
