We're told the new mother has moved on from PMK*BNC's Jill Fritzo, who has tirelessly represented the entire Kardashian clan for years, to Sarah Jessica Parker's publicist, Slate PR co-founder Ina Treciokas. She also represents Woody Harrelson, Owen Wilson, Liev Schreiber and Justin Theroux. Treciokas' firm also reps Jennifer Aniston.

A source tells us, "Kim wants to set herself apart from the Kardashian p.r. machine, and Kanye West advised her to build her own team."
