Kardashian tells ET that pregnancy is harder than she imagined and the changes to her body are difficult. She also tells McLarty that she is taking a lot of naps.
"I wouldn't say it's been easy," she said. "When people say that pregnancy is fun and they love it I would have to disagree. ... Even my sister has made it look easy, but it's not as easy as people think. ... I heard it's all worth it so I'm looking forward to that."
