Kim Kardashian Breastfeeding in Public

Keeping up with the Kardashians," but reality star Kim Kardashian may not be keeping up with the latest trends in breast feeding.

Last week, the 29-year-old television and Twitter vixen blasted a woman who was nursing her baby in a public restaurant.

"EWW Im at lunch,the woman at the table next 2 me is breast feeding her baby with no coverup then puts baby on the table and changes her diaper [sic]," Kardashian tweeted.

Later that day, she pulled back a bit and seemed to support breast feeding, although not in public: "My sister breast feeds! Its a natural beautiful thing, there's nothing wrong w it, but she covers herself, not w her boobs exposed" [sic]

Just like that, with two strokes of her blackberry, Kardashian unwittingly threw herself into the raging American debate on the proper place for breast feeding.

And the lactavists are a force to be reckoned with.

Earlier this month, more than 150 women marched on a Maryland mall after a woman was asked to leave for breast feeding in public, according to local television station WJLA.

Two years ago, pro-breast feeding moms put Facebook under fire, when the social networking site removed pictures of breast feeding women.

Even feminist hero Barbara Walters could not escape scrutiny. In 2005, she mentioned on air that a woman breast feeding on an airplane made her "uncomfortable." To help her get used to it, 200 breast feeding moms waited outside her window at ABC's broadcast center in New York.

The law is on their side.

Forty-four states have made it explicitly legal for women to pump in public, according to Mothering.com. And another 12 states, including New York and California, make it clear women can pump in the workplace.
