Rachel Zoe shared a few more pics of her 2-month-old son Kaius on Wednesday, and it looks like he went on quite the adventure!

"Kaius' first trip to the office...he loved meeting Team Zoe obvi #nofilterneeded #angel #kaiusjagger," the 42-year-old celeb stylist wrote on her Instagram account. "Look what happens on Kiaus Jagger's first day at the office with his @kendallelisec #instantlove #toocuteforwords #workingmom." So cute!

Zoe and hubby Rodger Berman welcomed their second child together in late December, and she stepped out just two weeks later with their 3-year-old son Skyler at Yogurt Stop in West Hollywood. Wonder when little K is going to join his big bro and mom for their almost daily stop for fro yo?
