Breast is best rhymes and is more or less true so we probably won't be able to do much about this one.
Nursing like a champ in reference to a latchy newborn. Are there nursing championships? How does one enter? What is the prize? Why does everyone say this?
Liquid gold designating colostrum. I think this might have originated in The Womanly Art, but I gave my copy away to a boob hell mom once my couch lost enough legs that I didn't need the book to prop it up any more. Incidentally, TWA is one of the books I see most often on the shelf at my nearest Goodwill. Haven't seen BH there yet.
I'm pretty concerned that breastfeeding lit won't become a serious subgenre until we get past these.
Oh, now I get it!
