"Happy Friday," Cobb, 35, simply wrote via Instagram on Friday, Nov. 1. Alongside the caption, the first-time mom shared a close-up picture of her little bundle of joy smiling big for the camera. Faison's look-alike son wore a blue and white striped pajama in the photo and showed off his brunette locks and baby brown eyes.
Earlier this month, Cobb also shared a sweet photo of her baby boy dressed in a white knit hat and a matching white shirt with a little cartoon hedgehog stitched on it. "And they say it gets even better," she gushed at the time. "I love my life."
Cobb and Faison, 38, tied the knot in December 2012 in Los Angeles and welcomed Rocco on Aug. 15. (Faison is also a dad to four kids from previous relationships.)
"Right when we decided we wanted to get married, we realized we wanted to have a baby," Faison told Us Weekly in May 2013 during Cobb's pregnancy. "We were very lucky, though -- we did it all in one weekend."
