While we wait for pictures of Kim Kardashian's daughter North West to surface and for Kourtney Kardashian to confirm whether or not she is pregnant with baby number 3, it seems that the sister have been at each other's throats.

Reports are surfacing that the "Keeping Up with the Kardashians" stars have been at odds over how Kim Kardashian and Kanye West's daughter should be raised, with the two sisters clashing over child rearing styles, according to The Hollywood Gossip.

An insider told the celebrity gossip site, "No one expected how opposite their approaches would be."

"Kim's shocked at how little they have in common. It's created a barrier instead of a bond." Apparantly Kourtney Kardashian has a very "laid back" parenting style whereas younger sister Kim, prefers to take the hands on approach.

The source revealed, "Kourtney scolds Kim for being too over-protective and highly strung."

"She keeps telling Kim you don't have to jump every time the baby makes the slightest sound... Kourtney breastfed her kids in public, which Kim thought was inappropriate.

"Kourt insists it's natural and a great way to lose pregnancy weight, whereas Kim has been pumping milk because she finds breastfeeding uncomfortable."

Kourtney Kardashian is already mom to Mason, 3, and Penelope, 1, with boyfriend Scott Disick, a source revealed that the star knew she wanted another child after holding her sister's daughter North.

The insider also said that, "Kourtney has that kind of glow she had with Mason and Penelope... they wanted to have one right after Penelope.

"I know Kourtney and Scott have been trying. So a baby now makes sense - it's very easy to get pregnant after giving birth once, let alone twice."
