The reality star, who has a 5-month-old nephew named Mason, revealed on Twitter that while having lunch at a restaurant, a woman exposed her breasts in public and changed a "dirty" diaper next to her.
The 29-year-old wrote: "EWW Im at lunch,the woman at the table next 2 me is breast feeding her baby w no coverup. Then she puts baby on the table and changes her diaper.
Hours later, Kardashian insisted that it is not "unsanitary" to breastfeed but that the woman should have covered up while dining out.
She added: "Misunderstood tweet - The woman had her boobs out at restraunt yest feeding then laid her on table and changed her with the food there. Unsanitary. My sister breast feeds! Its a natural beautiful thing, there's nothing wrong w it, but she covers herself, not w her boobs exposed.
"And you DON'T change a dirty at the dinner table... u use the restroom. Everyone was complaining! Just unsanitary.
