UPDATE: A representative from Kraft Foods reached out to HuffPost Food to clarify the origins of this ad. The ad was created by Kraft's ad agency, Cheil Worldwide, for a one-time use at an advertising forum and was not intended for public distribution or use with consumers.

Oreo as a brand is typically known as fun and kid-friendly. Those delightful birthday cake Oreos are a treat for the whole family to enjoy! But even Oreo can push boundaries sometimes. A recent ad in South Korea from Agency Cheil Worldwide features a baby breastfeeding, with the mother's nipple partially exposed. Alongside the ad is Oreo's slogan: "Milk's favorite cookie."

We'll give Oreo credit for using a different kind of milk than what comes in a carton, but the provocative ad might have a narrow reach. Perhaps the company has found reason to target breastfeeding women, or Mayim Bialik fans. (Or those that enjoy watching a woman breastfeed, we suppose).
