Hi C.,
With my little girl I cut the tip off of all of her pacifiers. When she would go to get one and put it in her mouth she soon realized that is was "broke". After one day of her going back and forth with the pacifiers she wanted nothing to do with them anymore. In fact she took all three of them and threw them in the garbage. I then told her what a big girl she was and clapped for her. She thought it was the greatest thing! The key is to let them realize on their own that they cannot use it, and decide that they are not needed anymore.
Good Luck!!
