Pregnant Jennifer Garner and Ben Affleck Pictures in LA

Jennifer Garner and Ben Affleck went their separate ways in LA yesterday afternoon. He was out near their Brentwood home taking care of the family dog, while Jennifer covered her baby bump and headed off to grocery shop at a nearby store. The couple are gearing up for the arrival of their third child, but Jen's been getting active on behalf of one of her favorite organizations, Save the Children.

Jennifer Garner wrote about childhood poverty in a new blog post for the charity. Jen wrote, "Children in this country start kindergarten when they are five or six years old. My daughters donʼt really understand this yet, but they've already won. Here is why: kids growing up in poverty have heard, by the time they turn four, 30 million fewer words than my kids. They are developmentally 18 months behind their middle class counterparts." She and fellow Save the Children ambassador Julianne Moore are urging fans to buy Save the Children's Valentine's Day cards, and the proceeds of the sale will benefit their efforts to eradicate childhood poverty in the US.
