Kathryn C. Dennis' Son Has Mastered the Art of Crawling

Kathryn C. Dennis and Thomas Ravenel's baby boy is on the move! St. Julien Rembert Ravenel, who will celebrate his first birthday in November, has started crawling, and if the below pic from his mom is any indication, he's already exceptional at it.

Yes, little St. Julien is certainly growing up, and he still looks absolutely precious in photos.

St. Julien's big sister Kensie, who turned 2 years old in March, also recently achieved a huge milestone in August: her first day of school, which Thomas documented on Instagram.

Prepare to say "awww" after taking a look at more cute pics of Kathryn and her kids, below.
