Nipple inversion in newborns may be a physiological cause and usually does not require special treatment. Newborn nipple inversion is related to the fact that all organs of the body are not yet developed during the neonatal period. Due to the low secretion of sex hormones, it may cause nipple inversion in newborns, which is a normal physiological phenomenon. As the baby grows older and the secretion of sex hormones increases, the baby’s body gradually develops and most of the inverted nipples can be protruded back to their normal shape. Therefore, it does not mean that inverted nipples in newborn babies mean inverted nipples when they grow up. So don’t squeeze your baby’s nipples, not only does it not work, but it can also cause serious infections. But it is important for parents to keep the baby’s breast area clean. Nipple inversion can be corrected at puberty if it persists. If the newborn has serious nipple inversion and other uncomfortable symptoms, it is recommended to go to the hospital in time, under the guidance of the doctor, improve the relevant examination, clarify the cause of the disease, and symptomatic treatment.
