Kris Jenner is not only an attention seeking mother, she's a great manager. She keeps all her children in check. Whether it be publicity wise, or weight wise. And if it is about weight, she starts them young. Like how she started Khloe on a gym routin when she was just 4 years old. From In Touch Weekly:
Kris Jenner's obsession with looks has reached a new high. The Kardashian matriarch not only wanted Khloe Kardashian to get a nose job at age 9 -- she had her working out at the young age of 4! In the new issue of In Touch, Kris' sister -- and Khloe's aunt -- Karen Houghton recalls how Kris would force Khloe, who's struggled with her weight her entire life, to exercise.

"Khloe might have been 4 or 5 years old when Kris would have me take her to classes to get exercise," Karen tells In Touch. "I would take her a couple of times a week."

Khloe has done all she can to build up her own self, but friends fear she'll never be able to tune Kris out completely. "Your parents are supposed to be there for you," says the insider. "You don't hurt your daughter like that."
See? Kris Jenner cares about her kids.
