Do I need to toughen my nipples before I breastfeed?
No, there's no need to do anything, as hormonal changes that happen in your breasts during pregnancy are preparation enough. You don't need to use creams to soften your skin beforehand, or express colostrum, either. Don't rub or scrub your nipples, as this will only hurt and may make breastfeeding difficult.
Your natural body odour plays a part in your baby bonding with you, and will help to get breastfeeding started. The areolas of your nipples release oil that naturally lubricates your nipples. This oil also smells of amniotic fluid, which is a familiar and attractive smell for your baby, especially just after he's born.
Your baby will soon learn that your breasts smell of you, colostrum and milk. These act as a strong draw to cuddle up with you and feed. So avoid using scented soaps, perfumes and body lotions in the early days of breastfeeding, particularly on or around your breasts.
