The pregnant star, who is due next month, toted her baby bump and her son, Camden, to New York City for an event for her Chinese Laundry shoe line.
The former "Hills" star showed off her growing belly and some serious cleavage in a figure-hugging midi dress as she entertained her little one.
"How Cam survives mommy work boredom...spinning around and around," she captioned the sweet snapshot with her 3-year-old tyke.
The proud mama shared another picture of her son this week, where he was seen sitting against a brick wall in a camo hoodie, gray sweatpants and tan boots.
Can you believe how big he is now?!
Cavallari recently talked about her kids in a new blog post, admitting that she makes a "conscious decision to make them my top priority."
"I want to take them to school, to mommy-and-me music class – I want to be there," she wrote. "This means I can't take on as many business endeavors, which has actually helped my career. I have to love and wholeheartedly believe in anything I do, which is a really great feeling."
Not only does Kristin make time for her kiddos, she also makes an effort to spend quality time with her husband, Jay Cutler.
"It's so important to make time for each other, even if it's just waiting to eat dinner after the kids go to bed. And even if it's takeout, light candles and make an effort to connect," she explained. "Also, you gotta have sex – men need it, and it's important for the relationship. It doesn't have to be all the time, but you have to get it in there sometimes!"
