Kristin Cavallari, former reality star and mother to Camden, her son with Bears Quarterback Jay Cutler, has stopped breastfeeding, telling "Hollywood Life" that Camden is now feeding on "a goat milk concoction that Jay found."

"It's hard," she told HollywoodLIfe.com while appearing at the Gillette "Kiss & Tell' event in Chicago on Jan. 29. "It was the hardest part of the whole thing and no one tells you that. I was a slave to pumping."

While Cavallari breastfed Camden for nearly six months -- that's longer than more than half of new American moms, according to the Center for Disease Control -- the lactivists are out in full-force online, deriding Cavallari for choosing her personal convenience over her child's well-being. One helpful mom, writing under the name "Elizabeth Aspen," points out that "Ted Bundy wasn't breastfed, either" at UsMagazine.com.

Let's give Cavallari some credit on this one. From the start, she was open about breastfeeding and the challenges. Despite the challenges, she stuck with it for six months -- again, longer than most American moms.
