Cavallari and her husband, Jay Cutler, are already parents to two boys: Camden, 3, and Jaxon, 1.

In an interview with American Baby, the former Hills star pointed out how it's important to talk to kids when they're upset rather than go straight for a punishment. One of her sons apparently threw a pretty big tantrum, which made Cavallari realize that he needed to talk instead of go in time-out.

"Just an hour ago, you would have thought I cut off one of Camden's legs," Cavallari said. "He threw the biggest fit because I gave him chicken instead of turkey. He started crying, which made Jaxon cry. It would be easy to get frustrated and start yelling, but I find that what a kid really needs is a hug. I'll say, 'Buddy, what's going on?' That's more effective than me scolding him or throwing him in a time-out."
