I weaned my daughter off her pacifier after her 2nd birthday. I started by only allowing her to use it when she took her nap and went to bed at night. No pacifier otherwise. Even when she cried I said no. If she wanted it, she had to lie down and sleep. When we go out I tried to distract her with anything else. Took awhile but after she got use to this, I took her pacifier away during her afternoon nap. I told her pacifier was only for night. She screamed and cried till she fell asleep. After the 4th day she just accepted it. A few weeks later I took away her pacifier completely. I told her it was dirty and I had to wash it. Again lots of screaming and crying but by than she kinda more accepting. She screamed more as a defiant thing but a few nights later she was sleeping without a pacifier. Some nights would be tougher than others but I stood my grounds.
