While not as scientifically rigorous as, say, the Daddy Types baby formula taste test, Steve at The Sneeze conducted a Breast Milk Taste Test. Actually, he spends most of the time talking about the containers. His breakthrough discovery:
breast milk + Hershey's chocolate syrup = Yoo Hoo!
One thing he didn't seem to figure out: In the time it takes his wife to pump that shot glassful, he could've driven to Costco and back for a whole case of Yoo Hoo!.
