The Chicago Bears officially have their cutest little fan – Camden Jack Cutler
has shared more adorable snapshots of her and Bears quarterback Jay Cutler's 7-week-old son
, who seems to be quickly picking up mom's sense of style.
In one photo, he's sacked out in a Bears jersey. In another, he's wide awake and peering out from under a white cap and sporting a matching long-sleeve white onesie.
"He's so excited about this win he can't contain himself," Cavallari wrote under the pic of Cam sleeping – referring to the Bears' victory over the Rams this past weekend.
"I like having this life that I'm responsible for," the reality star told PEOPLE earlier this month when she introduced Cam to the world.
