When a mother’s nipples are flat, depressed (larvate depressed, true depressed) or oversized, the baby may not suck the breast easily. When the nipple is undersized, the baby may not be able to suck at all. If your nipples are undersized, oversized, flat or larvate depressed, we recommend the following:   Nipple massage…Hold your nipple, pull it out, and then massage it. Massage using a nipple puller…Aspirate the nipple a little at a time, by lightly compressing the ball attached to the puller. These massages are effective if practiced 2 or 3 times each morning, afternoon and evening. A nipple shield may also help baby to suck well. Warm the breast with a hot wet towel before using the nipple shield. The forms of abnormal nipples differ with mothers, but many can be corrected by making the baby suck as often as possible. An effective method can be to pull out a nipple with a nipple puller before nursing and make the baby suck it immediately.
