Monday was take your baby to work day for first-time mom Kristin Cavallari!

Filming a cameo appearance on FX's The League, Cavallari, 25, toted her 7-week-old newborn, Camden Jack Cutler, around the Encino, Calif. set in between scenes. Earlier in the day Monday, a slender Cavallari cuddled her sleeping son at LAX airport.

"Being a mom is the most incredible feeling," Cavallari tweeted on August 11, three days after she gave birth to her and fiance Jay Cutler's first child in Chicago. "I am so in love with this little boy!"

Tweeting about additional photo shoots and media appearances this week in addition to her November 1 gig on The League, Cavallari has been hard at work to lose the extra pounds she gained while pregnant. "Walking uphill on the treadmill to work out this booty," she tweeted September 13. "Bye bye baby weight."

As she works to get her pre-baby figure back, Cavallari and Chicago Bears' Cutler, 29, are already considering giving little Cam a sibling.

"We were talking about the possibility of having another kid right away and then getting married so we can have two kids close in age," Cavallari — who put her wedding to Cutler on hold until Camden's birth — told Glamoholic. "We want four kids, so we're thinking maybe have one more, then get married, then have two more. But we'll see — it all depends on how the first one goes."
