A newborn’s inability to find the nipple may be caused by the newborn’s developing vision or the mother’s inverted nipple. After birth, the newborn’s vision may be developing gradually, and it may not always be clear that he or she can see the mother’s nipple clearly, which may cause the newborn to be unable to find the nipple when sucking after birth. As the vision matures, the nipple may be clearly visible. If the mother’s nipple is inverted due to congenital developmental abnormality, and the nipple is completely sunken into the areola, the newborn may not be able to find the correct position of the nipple. Frequent lifting and stimulation of the nipple by the mother is required and may result in effective improvement of the condition of nipple inversion. Newborns who are unable to find their nipples should seek the help of a physician specializing in obstetrics and gynecology as well as pediatrics.
