The postpartum nurse should include which of the following instructions to breast-feeding mothers?

(A) Limiting initial feeding times will only delay nipple soreness as well as the establishment of the letdown reflex, thus encouraging engorgement from clogged ducts and ductules. (B) Soap should be avoided because it may be excessively drying, predisposing nipples to cracking. (C) For optimal milk production, an additional 500 kcal over maintenance levels are needed daily. (D) Lipase, not lactose, emulsifies the fat in breast milk, making it almost totally digestible by infants.
