The Grey’s Anatomy alum is already contemplating the thought of getting pregnant again, despite only just giving birth a mere five weeks ago!
This is the 38-year-old’s first biological child, the actress clearly loved the experience.
“I still want more children,” Katherine confessed during her interview with People.
“I’d get pregnant again!”

But the starlet, who is mum, through adoption to daughters four-year-old Adalaide and eight-year-old Naleigh, says that she’d loved to expand her family in any way possible.
“I still am very inspired by adoption. I also have been thinking a lot about fostering.”
While the actress is clearly excited about the next step, she recently admitted giving birth is very different to becoming a parent through adoption.
“I actually prefer the adoption way because I wasn’t subject to hormones.”
She explained, “One minute you’re weirdly obsessed with this baby, like, ‘Don’t take him out of my sight,’ and the next you’re kind of blue, you’re a little sad and a little freaked out.”
One thing is certain, with their growing brood, the family has had lots to celebrate… but the party doesn’t seem to be slowing down any time soon.
Katherine’s husband, musician Josh Kelley, rung in his 37th birthday as a dad-to-three.
Katherine, who married her muso man back in 2007, marked the big day by sharing a darling Instagram post of her two boys.
“How @joshbkelley is finishing off his birthday, with sleepy snuggles from his namesake,” she gushed alongside a photo of Josh cradling their newborn.
“Could not be more grateful for this extraordinary man and for this extraordinary day that he was born!”
Adding, “Happy Birthday to the funniest, smartest, most talented, charming man I have ever met! Oh and he’s not too shabby in the Dad department either… is there ANYTHING the man cannot do??!!”
Earlier that day, the proud dad shared another adorable photo with his boy, joking, “Mom caught us nappin on the job!!!”
