Having three kids under the age of 7 is no small task!

But Ben Affleck and Jennifer Garner are doing a bang-up job and parenting their two girls and baby boy. The couple took all three for ice cream Saturday in Brentwood ... though it looks like Sam left with just a rattle rather than a double scoop.

Even though Ben's in the middle of filming Runner, Runner, most of which takes place in Puerto Rico, the actor is taking time off to be with his family ever chance he gets.

Affleck stars in two other films coming up -- Argo, which he also directed, due in theaters this October; and To The Wonder, which is set for release before the end of the year.
