According to the Center for Young Women’s Health, roughly 10–20% of females have an inverted nipple on at least one breast. You probably know that breasts come in all different shapes and sizes, but did you know the same goes for nipples? Actually, there are eight different kinds of nipples, says Dr. Tsippora Shainhouse, a board-certified dermatologist and pediatrician. All nipples are normal, and in fact, it’s possible to have a combination of two or more types (like protruding and bumpy, or flat and hairy). It’s also possible that your nipples don’t exactly fit into any of these categories — and that’s totally normal, too. This mechanism is important for breastfeeding or expressing milk, but it can also happen at other times. For instance, it can happen when a female hears their baby crying or even thinks about their baby. It can also sometimes happen when another baby cries. 11. Bumps on the areolae are normal.

If you’re unsure what size you need, talk to your lactation consultant. They’ll guide you on selecting the correct size and even demonstrate how to put on a nipple shield. How does a nipple shield work?

The most widely accepted theory is that cancer cells from a tumor inside the breast travel through the milk ducts to the nipple and areola. This theory would explain why this cancer is so rare in males. 15. People can get nipple tattoos.

Although most people have just one extra nipple, there have been at least two cases of people with seven nipples. 5. Nipples can occur anywhere on the body.

The options include using a nipple prosthetic, a skin graft, or a tattoo. 16. Nipple stimulation can induce labor. Fast forward to today, when fashion icons are putting their nipples on display with intention. In fact, nipples are now considered one of the hottest red carpet accessories ( we're looking at you, Kendall Jenner). With hashtags like #freethenips and #freethenipple, a braless moment or a tasteful nude is now considered a body-positive statement. After all, there are so many different types of breasts ( 9 types of boob shapes, actually) and nipples. Each person might have a different size, shape, or areola color, which isn’t something to be embarrassed about. In fact, your nipples are something to be proud of, because they’re part of YOU! The shield is too small if mom’s nipple expands and fills the entire tip of the shield or if it pulls through the holes on the tip (ouch!),” Peterson explains. “The shield is too large if there is lots of space between mom’s nipple and the shield, or if baby is unable to latch onto the nipple and areola.” According to an older study, there is also evidence to suggest that this secretion may attract newborns to the nipples. Your baby has a tongue-tie, tongue thrust or retracted tongue. These can be fixed or may improve over time.

Silicone is a great material for a nipple shield as it’s water-resistant and flexible, allowing the shield to fit perfectly and comfortably. It’s also more durable, so the shield should last throughout your breastfeeding journey. And, when compared to a material like plastic, it’s more eco-friendly, too.Session 7: Management of breast conditions and other breastfeeding difficulties. (2009).
