Carson recently opened up to PEOPLE about the "difficult" ordeal of contracting COVID-19 just before she welcomed her son in January.

"It's just crazy how it worked out," said Carson. "We were so worried for all those nine months of getting it, getting it, getting it. And then finally, when I actually really didn't need to get it, I got it. And we were so careful."

"It was really difficult, but I'm glad that we're past that," she added.

Since welcoming her son, Carson has also been candid about the changes her body has gone through. Last month, the professional dancer shared several photos of herself in a sports bra and leggings, writing that she was celebrating her body "the way it is."

"Progress not perfection ✨ being a dancer growing up & even throughout adulthood (especially throughout adulthood) I've always been self conscience [sic] about my weight and how I looked," the mom of one wrote.

"I've struggled with this & that's why I was hesitant to post these photos - I didn't feel I looked a certain way, 'good enough' & that was a sad thought to me," the Mirrorball Trophy-winner continued.

As Carson brought her post to a close, she noted that she's dedicated to learning "to celebrate my body the way it is now and celebrate the small successes to a HEALTHY body, spirit, and mind."
