Jennifer Garner & Ben Affleck Take Baby Samuel to the Beach

Baby Samuel is already making quite the splash this summer.

Nearly five months after Jennifer Garner and Ben Affleck welcomed their new addition, the whole family – including daughters Violet, 6, and Seraphina, 3 – hit the beach in Puerto Rico.

Photographs from earlier this week show Affleck, 39, on break from filming Runner, Runner with Justin Timberlake, cooling off in the waves as Garner, 40, hangs on tight to her baby boy.

Garner "is an incredible, spectacular, world-class mom," Affleck said last May.
