I went through the same thing with my son! It was so hard for me to see him with it that long because I always said I wouldn't be one of those mom's who's kid walked around with a binky after they were 1. About a month or 2 before his 2nd birthday, I finally just 'lost' it. I thought i'd left it at home when we went to grandma's to help pack up (she was moving) and when he asked for it, I had to tell him I didn't have one. Poor baby had a fit. We spent most of the day with me holding him for comfort. It was the hardest day of my life. Come to find out when I dug in my pocket for my keys, there was his binky :x I felt awful, but figured if we'd gotten through that one day, we could get through the next few until he forgot about it. He never looked back! Sooo, you could just lose it that way and see if he can forget it.
Another way I've heard of doing it, is pick a special day, and tell him that on this day, we have to say good bye to your binky. Then make a big deal out of him being a big boy, and that big boy's don't use binkys. have him put them in a ziplock baggie, and take them to the trash (just in case you cave later and he needs it, they will still be clean)
you could also try and see if he'd be willing to 'share' his binkies with another baby that dosen't have any. Let him put them in an envelope to mail to someone special, (just thought of this.. see if he'd send them to santa *if you do that*.. to show him how big of a boy he is...) That way he'd be able to say goodbye to the binkies and share them with someone else.. Not that I'm saying actually mail them, but you get my drift, right? Well, I guess I've rambeled on enough, I sure hope this will help you with a few ideas. Good luck! I pray he gives it up easily and never looks back!
