With football season now in full swing, Kristin Cavallari is keeping a routine when it comes to raising her two children, sons Jaxon Wyatt, 16 months, and Camden Jack, 3, with husband Jay Cutler.

“We’re used to having Jay around a lot for the last few months,” the television personality turned designer, 28, told PEOPLE of the 32-year-old Chicago Bears quarterback while at the Kristin Cavallari for Chinese Laundry shoe preview in Los Angeles on Wednesday.

“In the mornings, now, I’m by myself with the boys. I like the mornings with the boys, so I don’t mind that.”

However when the sun sets, the current mommy of two — who’s expecting the couple’s third child, a daughter, in November — finds it slightly more challenging.

“Cooking dinner, for me, is a little bit harder because Wednesdays and Thursdays, Jay doesn’t get home until around 5:15 p.m., and we usually eat around 5:45 p.m.,” she explains.

“I’m usually having to make dinner and it can be tough those nights because Jaxon, especially, needs a lot of attention. I’m usually holding him on one hip while I’m trying to cook.”

But the couple’s older son is all about Daddy — especially when he’s out on the football field.

“It’s really cute,” Cavallari, whose book Balancing in Heels will be out in March, says. “He’s really into [football] now and he tackles Jaxon — which is not good — but I’ve been taking him to the games and he’s been having a lot of fun.”

But Camden has picked up on one of Mommy’s quirks, as well.

“I swear a lot, so that’s been tough for me, but I’m trying really hard,” Cavallari admits.

“Camden said the F-word once. He said it like, ‘Mommy, why did you say f—?’ so he didn’t just say it for no reason. It really makes you catch yourself and make you be aware of what you’re saying all the time.”

In between playing referee to her boys, Cavallari has been busy prepping for the family’s new addition to arrive.

“I just discovered that Zara makes little girl clothes, and oh my God, their stuff is amazing. I just ordered a bunch and I’m hanging everything up in her closet now — of course, it’s all pinks and purples,” she shares. “I finally got her first little tutu, so we’re definitely having fun.”

Lucky for Cavallari, her pregnancy this time around has been “the exact same” as it was with the boys — aside from one notable difference.

“I feel like I’m carrying slightly higher, so there must be some truth to [what] they say, you lose your shape with girls because you carry them higher and have no waist anymore,” the mom-to-be explains.
