Should I try to toughen my nipples for breastfeeding?
Nope. Not only is it unnecessary, but, as mentioned above, doing so may trigger preterm labor. Plus, as Neifert notes: “Nipple tissue is not callus-forming tissue, so you can’t really toughen them; you might even damage the sensitive skin and make breastfeeding uncomfortable.” If you want to feel like you’re doing something to prepare, use ultra-pure medical grade lanolin on your nipples to keep the skin supple.
