My daughter had a paci until she was 2 and a half. About 2 months ago, my boyfriend opened the window and told her how fun it would be to throw it out the window. I couldn't believe it, but she did it. That night she didn't ask for it and went straight to bed. The next night, she cried a little for it but eventually went to bed and hasn't had a problem since. Sometimes she asks about it and she'll tell me she wants to go get it, but I just tell her that there's bugs all over it and it's all dirty and she doesn't need it anyway and then she just says ok and goes on with whatever she's doing. I was impressed because I had tried telling her the paci fairy was coming to take her pacis and give her a present and i gave her a barbie camera to replace them but that didn't last long and i tried throwing them away. I think the act of throwing it out and her actually doing it, she knew it was gone forever. I don't know. Try it. See what happens. It worked for me.
Another idea I had after she was already off of it was to take her to build a bear and let her pick out her bear and get it stuffed and instead of putting a heart inside, put her paci in it so she can still go to bed with it, it's just inside the bear. When I thought of this, I was kinda upset that I didn't think of that sooner, but oh well. I'll prob try it on my next kid. Good luck!
