Does Kourtney Kardashian Think Her Sister Kim Is 'Selfish' For Taking Newborn On Kanye West's Tour?

Rumors have circulated that mama-to-be Kim Kardashian will be taking her newborn baby with her while she joins boyfriend Kanye West on his world tour this fall, but a source tells RadarOnline.com that her sister Kourtney thinks the decision is selfish.

The source claims that Kourtney feels having a newborn on tour is "not in the best interest of the infant," and the idea of Kim bringing her baby along has angered her reality star sister. It was apparently Kim's decision to bring the baby along on the tour, which will follow the release of West's upcoming studio album set to drop in June, just one month before Kim is due to give birth to their baby.

Kim's decision to bring the baby along on tour The decision has "seriously irked Kourtney," the source told Radar. "She thinks it's very selfish of Kim to take the baby on tour with Kanye. Babies need stability, and a schedule, which will be very hard to do when changing time zones and hotel rooms.

"It's also potentially dangerous to the baby's health because of their developing immune systems," the source said. "The drama between the sisters is being filmed and documented for the upcoming season of 'Keeping Up With The Kardashians'. Kourtney just doesn't think Kim grasps the huge change that will happen once the baby is born."

However, the insider also said that the fighting between the Kardashian sisters is "nothing new," saying that "this is what they do."

"Kourtney loves Kim, and even though she disagrees with some of the decisions she is making, they will get through it," they said to Radar.

Kim and Kanye West's relationship has been the subject of much media scurnity, with West currently under fire for allegedly having cheated on his girlfriend with her fashion designer friend, Riccardo Tisci. The media has also criticized the couple for spending so much time apart in the wake of Kim about to give birth to their first child.
