My younger daughter was obsessed with her binky from birth until 2.5, when the dentist told us we had to take it away (causing problems with her teeth). On the advice of some Mamapedia moms, I cut the tips off of all the binkies in the house. My daughter went to the binky drawer (yes, we had an entire drawer for them) and tried them one after the other. She got a puzzled look and told me, "They're all broken!" And that was the last of it. She never wanted them after that. Honestly I had been prepared for weeks of drama, tears, and everything else. But all it took was to "break" the binkies by cutting the tips off, and she didn't want them anymore! Easiest thing in the world. You could've knocked me over with a feather.
Maybe it will work for you, too. Good luck!
