Well, I think the myth that this particular ad is trying to dispel is the objection to breastfeeding on the grounds that your husband won't find you sexy anymore. Once you've started, the reduced sex drive isn't usually a barrier to continued nursing. It's your body's natural way of making sure you don't get pregnant again... both pregnancy and nursing significantly depletes your body's resources. It's possible to overcome or outwait the libido drop... it DOES come back, and with a vengeance! ... but you only get one chance to nurse your kiddo.
