To start with, I am very specific with the items I buy for my kids. The NUK brand is made in the Germany which is known to be one of the leaders in the baby products for years. The NUK orthodontic pacifiers are very common in Europe. The pacifiers are anatomically design the way they do not interfere with teeth development and tongue placement. In fact, this is was the only pacifiers my baby would take. We were given a bunch of other pacifiers on my baby shower and in the hospital, but all of them now collecting dust:) The pacifiers come in several designs (plain and print) for boys or girls, or unisex. The pacifiers are very easy to clean. I do wash them with dishwasher soap every day and boil them once a week. They are made of very sturdy silicone. My teething baby was chewing on them all the time. We have NUK bottle and they have exactly the same nipple design, which make baby less confused when switching between bottle and the pacifier. I do recommend NUK pacifiers for anyone. Great product!
