"Beautiful mama, beautiful boy," one of Katherine's 1.1 million Instagram followers commented on the pic with another adding, "He is so precious — beautiful photo!"

Katherine and her musician husband, Josh, welcomed Joshua Bishop Kelley, Jr. on Dec. 20, 2016. The couple — who tied the knot in December 2007 — previously announced they were expecting their first biological child together last June.

"It was totally unexpected but thrilling," she wrote on her blog, ThoseHeavenlyDays.com, after revealing her pregnancy news. "The whole pregnancy thing is new to me but the thrill of having a baby is not."

The star and Josh, 37, are also parents to two older daughters, Naleigh, 8, and Adalaide, 4. They adopted Naleigh from South Korea in September 2009 and Adalaide from the US in April 2012.

“[Naleigh] is my very, very smart, very compassionate, very big-hearted little gal. She’s totally Mommy’s little helper and loves being the big sister," Katherine told People of her eldest daughter after welcoming baby Joshua.

"Adalaide has so much just inherent self-esteem, which I am so proud of and so grateful for," the proud mom continued. "When you’re raising girls, you want them to be confident and you want them to love who they are. With Adalaide, I’m not gonna have any problems with that."

So, is Katherine eager to expand her brood even further in the future? "I still want more children,” she revealed. "I’d get pregnant again, and I still am very inspired by adoption. I also have been thinking a lot about fostering."
