Inverted or non-protractile nipples are common among women, causing psychological distress and making breastfeeding difficult for both mother and baby. Inverted nipples occur due to short lactiferous (milk-bearing) ducts that tether the nipple and prevent it from projecting.The Philips Avent Niplette is a simple, painless device that women of all ages can use to correct inverted or non-protactile nipples. Using suction to gently stretch the lactiferous ducts over time, it can be tucked discreetly within the bra and achieve a permanent correction after one to three months of continuous use at eight hours each day.
