Jennifer Garner Samuel stripes park seraphina

On Monday afternoon Jennifer Garner took her three children to the park in Los Angeles, and she looked thrilled to be on mommy duty with Seraphina, Violet and Samuel. It's amazing how quickly little Sam has grown up -- he's definitely not a baby anymore!

Or is he just putting his game face on and getting ready to get back into work mode for Live By Night, which he wrote and is set to direct and star in?
