T.H.
My son became attached to the paci when I weaned him at a year. When it came time to give it up, we took the gradual approach, finally limiting to bedtime only and made a special pillow with a pocket to keep on his bed. We had him put the paci in the pocket so he had some control of the situation. After a while, some days he would forget to get it out and eventually (about 3&a half) he no longer asked for it.
