Mothers with various shaped/sized breasts/nipples can breastfeed. Babies breastfeed, they don’t nipple feed. Truly inverted nipples (ie where the nipples are completely stuck inwards) are very rare. Some mothers have nipples that don’t stand out or nipples that take more ‘coaxing’ to come out. With good help and persistence, most mothers find that breastfeeding becomes easier and that their nipples stay out more and more as their baby gets better at breastfeeding. Even if your baby has problems at the start, he will eventually get the hang of it, as long as you maintain a good milk supply.
