Meet Tennessee James Toth!

Reese Witherspoon gave us a peek at her 6-week-old son while out and about in California on Wednesday.

The actress’s third child — her first with husband Jim Toth — arrived Sept. 27 in Santa Monica, her rep told PEOPLE exclusively at the time.

Although Witherspoon, 36, has stepped out solo since the arrival of her baby boy, this is the first time she’s been spotted with her new son.

“Everyone is bonding with the baby,” a source tells PEOPLE of the relationship Witherspoon’s elder children — Deacon, 9, and Ava, 13 — have with their new little brother. “And Jim has had a lighter workload and has been spending a lot of time at home with the baby as well.”

Adds a Witherspoon pal: “She’s so content. Tennessee is a great little guy and he’s fitting right into their family. Jim’s been incredibly supportive, pitching in with Ava and Deacon and generally just being someone for Reese to lean on. They’re all very happy.”
