Given that Kourtney Kardashian is pregnant with her third child, we assume she knows a thing or two about parenting. But does that make her fit to criticize her her sister's mother skills? Probably.
Then again, anyone who's seen Kim Kardashian take North West to a Fashion Week runway show is qualified to assume that she's Kim's the most selfless mom.
"They have opposite parenting styles," says a source close to Kourtney and Kim. "Kourtney is very hand-on and all about doing kid things with her kids, not adult things."
"She thinks Kim parading North around is terrible. Kourtney would never bring her kid into a paparazzi storm like Paris Fashion Week or sit front row at a fashion show with her kids.
