Kristin Cavallari and Jay Cutler recently welcomed their second son, Jaxon, into the world, and the former reality star revealed to Michigan Avenue they will probably have one more child -- perhaps a sister for her two little boys?

"Motherhood is a lot of work," she told the publication.

"Before we had children, Jay and I wanted four, and now we're thinking three."

The blonde beauty continued, "We love having kids, so I do think we'll end up having another one but then we're done."

Aside from three month old Jaxon, the couple has a two-year old son, Camden.

"Being pregnant for a full nine months isn't the best thing in the world," Cavallari added.

"The Fabulist" host explained how life at home is challenging, especially since her sons are on different schedules.

"He's a happy baby, except that he's not a great napper, so I'm working on trying to get him to take better naps right now which is all I can really ask for," the blonde beauty said of Jaxon.

"When Camden's going down, Jax is just waking up to eat and play, so there's literally no time. You have zero time to yourself."

However, Cavallari revealed she is more relaxed being a mother for the second time.

"Well, it's a lot easier in the sense that you know what to do and expect, so you have a lot more confidence," she explained. "Plus, you're definitely more relaxed with the second one because you're not stressed out by questioning everything that you're doing."

The couple welcomed Jaxon in May, and Cavallari shared an adorable snap with fans on her Instagram account. She recently spoke to E! News about getting her pre-baby body back.

"I started working out when Jax was three weeks old," the TV star revealed.

"I've been working out four to five times a week for 30 to 45 minutes at home, doing tons of leg work like squats, lunges and lifting weights."

She even plans on stepping up her already impressive regimen.

"I want to start Pilates again to focus on my core. I'll probablyget back into it in the next couple weeks," the reality star said.

She added, "I'm still a couple of pounds away from my pre-pregnancy weight, but it took a solid three months with Camden and I think it will be the same this time."
