This is a nipple shield for breastfeeding mothers to protect cracked nipples and for inverted nipples to help babies latch on. I purchased it online in a hurry when my baby was 10 months old and had teeth, and it hurt when they bit me. I used it once. My baby didn't get used to the nipple shield and wouldn't suck on it at all, so I didn't use it again. The box will be folded for shipping. It has been used once. Please understand this before purchasing. Target age: From 0 months As a bonus, I will include Milton sterilizing tablets for baby bottles. I am also selling other baby goods. Bundle sales are welcome!
