The people of the Middle Ages didn't have the same shrinking from natural bodily functions that we have inherited from the Victorians. . . . and they also didn't have the strident insistence on them that the La Leche League/hippy types have . . . . a nice, happy medium.

I worked on a dairy farm one summer, and some time back I had showed my daughter how you milk a cow. She is doing a biology field studies program in Costa Rica, and they toured a dairy farm yesterday -- the farmer let the biology students try to milk a cow (mostly so they could laugh at the city slickers, I'm sure!) and daughter was the only one who was able to get milk out of said cow. She was SO proud that the farmer complimented her. No knowledge is ever wasted!
