Her first child's not even 1, but Kristin Cavallari is already dreaming of siblings for her son, Camden.

"I'm addicted to motherhood," Cavallari, 26, admitted at QVC's Red Carpet Style event in Los Angeles on Friday. "It's a lot of fun. We want a bunch of kids."

In the meantime, Camden, who arrived in Kristin and Jay Cutler's life last August, has already passed a few baby milestones.

"He's 6 months old now, which is crazy how fast everything just flies by," Cavallari told reporters. "He has his two bottom teeth. We think he's teething and getting another one. He's eating food and he's just laughing and smiling all of the time. It's so fun."

The "Hills" alum also noted that her little guy is putting his two teeth to work by chowing down on veggies like avocados and zucchini -- which means she has a little more time to devote to date nights with her NFL-star fiance.

"I think the most important thing is to just make time for the relationship," she said. "It's really easy to just stay in sweats all day and not wear any makeup. I think that's fine, but once or twice a week, I think you should just put a little effort into it and try to make dinner and have dinner not in front of a TV, just keep that connection."

Cavallari and Chicago Bears quarterback Jay Cutler announced they were engaged again in November 2011, a few months after briefly calling off their initial wedding plans.
