Kourtney: Why I Stopped Breast-Feeding

Kourtney Kardashian tells E! Online that she stopped breastfeeding 15-month old son Mason last week.

"It's traumatizing!" said the Kourtney and Kim Take New York star, 31.

Kardashian, who adds she gained five pounds since weaning her babe, said she put it off for as long as possible.

"Everyone would say it's time, it's time," she said. "So I started to stop a little, and then I was like if I'm happy and he's happy."

Finally she let Mason be the one to decide.

"He just stopped asking," said the reality star. "It's really sad, but it's natural."
