Nuk's are the best pacifiers on the market! I tried several with my daughter, and the Nuk was the only one she consistantly liked. She took to it instantly and it helps soothe her whenever she is trying to go to sleep or feeling grouchy, like after getting a shot. They are pretty inexpensive and easy to wash. The only downside is that sometimes when you wash them, water gets trapped inside. It's really annoying, because then it makes a noise every time she sucks on it - I'm always afraid it will keep her from falling asleep. You can get the water out, but you have to squeeze the water out manually - it takes a few minutes. This is the only downside though - it is the only pacifier that I would buy.
