Mommy duty seems to really agree with Reese Witherspoon! The Devil's Knot actress looked radiant as she and husband Jim Toth juggled a few of her infant son Tennessee's necessities -- and Tennessee himself! -- during an outing in Santa Monica on Wednesday, Jan. 30.

Witherspoon, 36, kept things monochromatic in a black-and-grey outfit complete with grey knit cap, and Toth, 41, followed close behind in a sharp suit, carrying their happy bundle of joy, now four months, in a grey car seat. The new father looked protective as he gazed down at Tennessee, whose face was hidden by the car seat covering.

The Oscar winner gave birth to her third child (her first with Toth) on Sept. 27, and has been spotted doting on him in public a few times since. Witherspoon is also mother to daughter Ava, 13, and Deacon, 8, with ex-husband Ryan Phillippe.

In an interview with Chelsea Handler back in December, the proud mom called her newborn son "super cute" and raved about how daughter Ava was being such a great big sister: "She's so awesome!"

"The kids met the baby the first day at the hospital," a source told Us Weekly shortly after Tennessee's arrival. "Deacon is excited to have a brother. And Ava can't wait to babysit!"

Toth, meanwhile, has been a solid pillar of support for Witherspoon, and "has been there for Reese every step of the way," the source added.
