Witney Carson Documents 10-Month-Old Son's First Thanksgiving with Cute Photos: 'Pure Joy' Last month, the dancing pro had a very special visitor backstage at Dancing With The Stars when her toddler spent some time on set with her. Before hitting the dance floor with partner Wayne Brady, Carson spent some quality time with her family backstage. In posts shared on her Instagram Story, the dancing pro sat with McAllister and son Leo and read a book together. The toddler adorably leaned into the page and pretended to bite the apples on it with his dad, saying, "Watch." "His favorite thing to say is 'watch watch watch' over and over hahaha," Carson wrote.

I had stretch marks before pregnancy as well. Never was something I was embarrassed about," she said. "I guess when I found them the other day in a new spot I was emotional & in the process of accepting my new momma body." She continued, "Again, I'm super proud of them & think they are a beautiful symbol pregnant or not."
