Kim Kardashian has left the house with daughter North West right by her side. TMZ photographed the new mom with baby Nori, Kanye West and a nanny heading into a Los Angeles medical facility.

Kardashian kept the baby hidden under a blanket in her car seat and tried to cover up her post-pregnancy body under a heavy layer of clothing but she did look skinnier.  

According to the Daily Mail, a source recently told US Weekly that the "Keeping Up With the Kardashian" star had already lost 30 pounds but was still working hard to get rid of the last 30. The source claims she is "obsessed" with reaching her goal weight of 115 pounds.

"She's extremely self-conscious about her current body," the source told Us Weekly. "She said when she comes out and gets photographed for the first time she wants to look hot, hot, hot."

The source said that Kardashian is upset that the weight isn't dropping as quickly as she thought it would. To help her get her pre-pregnancy body back she enlisted the help of celebrity personal trainer Tracy Anderson.

"The weight is not coming off as quickly. She plateaued. This is the hard part now," a different source told the magazine. "She's always complaining about her size. She says she hates locking this way and won't go out again until she is skinnier."

Anderson has the 32-year-old on a strict exercise and diet regime and said her client will be back in bikini shape in no time. She told US that she was going to let Kardashian rest for six weeks and then begin training at least four times a week.

She said the fitness regime wouldn't include regular crunches or "anything like that" but her main focus would be getting her abdominal muscles back in shape.
