Jennifer Garner had her son, Samuel Affleck, in tow as she ran errands in LA on Thursday. The actress had a smile on her face as she held on to her little one; is it us or is Samuel really rocking those choo-choo-train PJs? Jen is back to her usual routine on the West Coast after making a quick trip to Japan for a Max Mara event. As the face of the brand's accessories line, Jen hit the red carpet in a sexy white gown to help celebrate the Tokyo store's 25th anniversary.

While Jen was overseas, her husband, Ben Affleck, reported for daddy duty. Ben, who is currently filming Gone Girl in and around LA, broke from work responsibilities to take daughter Violet to her basketball practice over the weekend. Before Jennifer headed to Japan, she and Ben joined forces to take their kids trick-or-treating in their Brentwood neighborhood on Halloween.
