With two kids and a newborn, Jennifer Garner and Ben Affleck have learned to find a tender moment whenever they can -- even if it means just holding hands during an errand run, as the two did March 30 in Santa Monica.

"You steal time," Garner has said about maintaining her relationship with her husband of nearly seven years. "You steal a date, you steal a kiss, you steal a whisper."

And the arrival of son Samuel, 5 weeks old, "has brought them closer," says a source of the couple, both 39, also parents to Violet, 6, and Seraphina, 3. "Ben and Jen couldn't be happier."

Their joy was evident during a recent date night at Santa Monica's Giorgio Baldi restaurant. Says an onlooker, "They really enjoyed the one-on-one time."
