Salma Hayek's "left breast has now done more for humanity in a few minutes than I've done in roughly my whole life," said Margaret Lyons in Entertainment Weekly. On a trip to fight tetanus in Sierra Leone, the actress and UNICEF ambassador breastfed a malnourished infant in a Nightline video, highlighting the importance of breastfeeding to reduce mortality.

That depends on whom you ask, said Julie Deardorff in the Chicago Tribune. Motherwear's breasteeding blog was "blown away" that this was shown on network TV, while suggests Hayek is just trying to one-up Angelina Jolie. Whatever her motives, Hayek should be commended for using her breasts "as nature intended: She fed a hungry baby."

Yes, but don't try this at home, said Angele Sionna in "Sharing breast milk is not a new concept"—wet nurses did it for centuries—but many advocates discourage sharing over safety concerns. Still, if Hayek has inspired you, there are safe ways to share breast milk, such as donating to milk banks that screen before distribution.
